Nuclear power stations represent the pinnacle of engineering consequence. Every subsystem \u2014 from the primary coolant loop down to the smallest pneumatic actuator on a safety-related valve \u2014 must perform precisely, consistently, and without exception, across operational lifetimes measured in decades rather than years. Hidden within the vast web of utilities that keep a nuclear facility safe is one that receives little public attention but carries enormous technical weight: instrument air. This is the compressed gas backbone that drives pneumatic positioners, actuates containment isolation valves, powers the logic circuits of safety instrumentation systems (SIS), and enables the emergency reactor trip mechanisms to respond within milliseconds when demanded. In the language of nuclear engineering, reliable, uncontaminated instrument air is not a convenience \u2014 it is a safety function.<\/p>\n

The stakes are captured succinctly in a single scenario: if instrument air contains even trace quantities of lubricating oil \u2014 measured in parts per million \u2014 that contamination can form deposits on valve diaphragms, block instrument tubing orifices, and cause spring-opposed safety valves to fail-in-place rather than fail-safe. In a conventional industrial plant, such a failure might trigger a process shutdown. In a nuclear environment, the consequences can escalate rapidly through multiple defence-in-depth barriers. This is precisely why nuclear safety standards worldwide, including those referenced by the International Atomic Energy Agency (IAEA), the UK’s Office for Nuclear Regulation (ONR), and equivalent bodies across Europe and Asia, mandate that instrument air serving nuclear safety-class systems must be produced by oil-free compressor technology \u2014 with zero tolerance for hydrocarbon contamination.<\/p>\n

Ever Power has spent more than 18 years engineering oil-free screw air compressors specifically for applications where performance is measured against regulatory standards rather than catalogues. Our nuclear-grade instrument air compressors are deployed in safety-critical environments across the UK, mainland Europe, and major nuclear programmes in Asia, including installations supporting the third-generation Hualong One (HPR1000) and AP1000 reactor builds. Whether you are specifying equipment for a new nuclear build, a plant life extension programme, or a decommissioning support facility, this article sets out exactly what the technology demands \u2014 and how we deliver it.<\/p>\n<\/div>\n<\/div>\n

Technical Background<\/p>\n

Why Nuclear Safety Systems Cannot Tolerate Oil in Instrument Air<\/h2>\n

To understand why an oil-free screw air compressor is the only viable solution for nuclear instrument air, you need to understand how pneumatic safety systems behave when contaminated. Nuclear safety-related instrumentation and control (I&C) systems typically use instrument air at supply pressures between 5.5 bar(g) and 8.5 bar(g) to maintain valve positions, operate dampers, and bias spring-loaded trip mechanisms. These systems are designed on the fail-safe principle: if air supply is lost, valves revert to their safe position (typically closed for containment isolation, open for reactor trip). This is well-understood and managed. What is far more dangerous is a condition in which air supply is present but degraded \u2014 where oil aerosols or vapours have begun to coat sealing surfaces, create stiction in positioner slides, or polymerise on diaphragm faces, causing valves to stick in the wrong position under partial pressure conditions.<\/p>\n

ISO 8573-1 Class 0 \u2014 the governing standard for oil-free compressed air \u2014 specifies total oil concentration (aerosol, liquid, and vapour combined) of less than 0.01 mg\/m\u00b3, a level that cannot be reliably achieved by oil-lubricated compressors with downstream filtration alone. Nuclear regulators, including the UK’s ONR (which references IEC 61513 and IEEE 603 for nuclear I&C), require documented proof of air quality at the point of use, not merely at the compressor outlet. Oil-free screw technology eliminates the contamination risk at source. There is no lubricant in the compression chamber, no oil carry-over to filter, and no risk of filter failure causing a downstream contamination event. The oil-free screw air compressor is therefore the only technology class that satisfies both the letter and the intent of nuclear safety standards for instrument air quality.<\/p>\n

Beyond contamination control, nuclear applications impose a second layer of requirements around reliability and availability. Unlike commercial industrial compressors that may be taken offline for routine maintenance during a planned shutdown, nuclear safety-related instrument air systems must remain in service continuously during plant operation, including during refuelling outages when certain safety systems remain active. This drives the requirement for redundant configurations \u2014 typically N+1 for non-safety-critical instruments, and 2N or 2-out-of-3 redundancy for safety-class applications. Every Ever Power nuclear instrument air compressor package is designed around these redundancy philosophies, with automatic standby switching, continuous condition monitoring, and maintenance access features that allow servicing of individual compressor trains without interrupting supply to the safety systems they serve.<\/p>\n<\/div>\n<\/div>\n

<\/p>\n

\n
\n

How It Works<\/p>\n

Operating Principle, Materials, and Construction<\/h2>\n

The oil-free screw air compressor operates on the twin-rotor positive displacement principle. Two precision-machined helical rotors \u2014 a male rotor with typically four lobes and a female rotor with six flutes \u2014 rotate in mesh within a thermally managed stator housing. As the rotors turn, air is drawn in at the inlet and trapped in the decreasing volume between rotor profiles and the stator bore wall. This trapped air is compressed along the rotor length until it reaches the discharge port, where it is released at the required working pressure. Because there is no lubricant in the compression space, the male and female rotors must maintain a precise running clearance \u2014 typically measured in microns \u2014 without contact. This is achieved through external timing gears that synchronise rotor rotation without load transfer, and through special rotor profile geometries that keep inter-rotor leakage within acceptable efficiency limits without requiring any sealing medium.<\/p>\n

The materials chosen for nuclear instrument air service go significantly beyond commercial grade. Rotor bodies are typically manufactured from high-alloy steel (such as 17-4PH or EN 1.4418 duplex stainless grades) to resist corrosion from humid intake air and provide dimensional stability across the full temperature envelope. Stator bores are coated with PTFE-composite or thermally sprayed ceramic coatings that eliminate metallic particle generation in the compression space \u2014 a critical concern in nuclear environments where downstream air quality is sampled and documented as part of the facility’s safety case. Intercoolers and aftercoolers are constructed from 316L stainless steel or duplex alloys to prevent oxide particle shedding into the air stream. All elastomeric seals in contact with instrument air are specified in FKM (Viton) or FFKM grades to resist chemical degradation and outgassing at elevated temperatures. The complete air path \u2014 from intake filter to discharge outlet \u2014 is designed to be free of any hydrocarbon-based material that could contribute to contamination under normal or fault conditions.<\/p>\n

For multi-stage configurations used at higher delivery pressures (above 10 bar, sometimes required for high-integrity isolation valve actuators), the same oil-free principle is applied in series stages with intermediate cooling. Water injection two-stage designs \u2014 where demineralised water replaces oil as the sealing and cooling medium \u2014 are available for applications requiring maximum reliability with simplified sealing technology, though at the cost of added water treatment infrastructure. Ever Power offers both dry oil-free and water-injected configurations, matched to plant layout, utility availability, and the specific demands of each nuclear instrument air application.\"hava<\/p>\n<\/div>\n<\/div>\n

Six Core Advantages of Our Nuclear-Grade Oil-Free Screw Compressors<\/h2>\n
\n
\n
\ud83d\udccc<\/div>\n

ISO 8573-1 Class 0 Guaranteed<\/h3>\n

Zero oil content in the compression path means zero risk of hydrocarbon contamination downstream. No filtration dependency, no upstream failure modes, and full compliance with nuclear instrument air quality requirements without compromise.<\/p>\n<\/div>\n

\n
\u26a1<\/div>\n

Proven Redundancy Architecture<\/h3>\n

Standard N+1 and 2N configurations are engineered from the outset, not retrofitted. Independent control circuits for each compressor train, automatic switchover without operator intervention, and real-time condition monitoring ensure continuous availability through any single-equipment failure.<\/p>\n<\/div>\n

\n
\ud83c\udf20<\/div>\n

Seismic and Environmental Qualification<\/h3>\n

Nuclear instrument air compressors are qualified to IEEE 344 and IEC 60980 for seismic performance, with shake-table test data available as part of the equipment qualification dossier. HEMP, temperature cycling, and humidity exposure qualification also available on request to meet site-specific design basis requirements.<\/p>\n<\/div>\n

\n
\ud83d\udcca<\/div>\n

Full Document Package for Nuclear QA<\/h3>\n

Every compressor package is supplied with a comprehensive nuclear quality assurance documentation set: material traceability records, weld inspection reports (RT\/UT\/PT to AWS D1.1 and ASME IX), hydrostatic test certificates, factory acceptance test (FAT) records, IQ\/OQ\/PQ validation protocols, and a complete equipment qualification report (EQR) formatted to IAEA NS-G-1.4 guidance.<\/p>\n<\/div>\n

\n
\ud83d\udd27<\/div>\n

Long-Life, Low-Maintenance Design<\/h3>\n

The absence of oil in the compression cycle eliminates the most common maintenance consumable in conventional compressors. Our nuclear designs target 40-year design lifetimes with planned major overhaul intervals aligned to refuelling outage schedules, typically every 8 to 10 years. Spare rotor cartridges are maintained by the plant for rapid on-site exchange.<\/p>\n<\/div>\n

\n
\ud83d\udcf1<\/div>\n

Integrated Condition Monitoring<\/h3>\n

Our nuclear instrument air compressors ship with vibration sensors on rotor bearings, inter-stage and discharge temperature transmitters, differential pressure monitoring across intake filters and aftercoolers, and discharge air quality analysers (online oil and moisture detection). All signals are hardwired to the plant DCS or standalone safety PLC via galvanically isolated 4\u201320 mA or Modbus RTU interfaces.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

<\/p>\n

\n

Where Our Compressors Are Used<\/p>\n

Application Scenarios Within Nuclear Power Facilities<\/h2>\n

The oil-free screw air compressor package does not serve a single instrument air header in a nuclear plant \u2014 it typically supplies air to multiple distinct safety systems, each with its own pressure, flow, and quality requirements. Understanding the specific applications helps clarify why nuclear-grade equipment, rather than general industrial kit, is the only appropriate choice. The following scenarios are drawn from actual project experience across pressurised water reactor (PWR), boiling water reactor (BWR), and advanced gas-cooled reactor (AGR) platforms, as well as next-generation designs currently under construction or regulatory review in the UK and Europe.<\/p>\n

\n
\n

\u25cf Safety Instrumentation Systems (SIS)<\/h3>\n

Pneumatic logic solvers, partial stroke test (PST) actuators, and position transmitters across the safety-related I&C architecture require clean, steady instrument air at 5.5\u20137.5 bar g. Any contamination at this level propagates directly to reactor protection system reliability.<\/p>\n<\/div>\n

\n

\u25cf Containment Isolation Valves (CIV)<\/h3>\n

CIVs are the primary mechanical barrier between the inside of the containment building and the external environment. Pneumatically operated CIVs must respond within seconds of a containment isolation signal. Instrument air quality failures that cause a CIV to hang open represent a direct breach of the containment barrier function.<\/p>\n<\/div>\n

\n

\u25cf Emergency Core Cooling System (ECCS) Valves<\/h3>\n

High-pressure injection and accumulator isolation valves in ECCS trains are among the highest-consequence pneumatic applications in a nuclear plant. Actuator reliability directly influences the plant’s emergency cooling capability and its ability to prevent core damage during a loss-of-coolant accident (LOCA).<\/p>\n<\/div>\n

\n

\u25cf Main Steam Isolation Valves (MSIV)<\/h3>\n

MSIVs must be capable of closing within seconds of a main steam line break signal, terminating steam flow from the reactor steam generators. High-force pneumatic actuators on MSIVs draw significant air volume at closure; the instrument air compressor package must be sized to support rapid transient demand without pressure droop below actuator minimum requirements.<\/p>\n<\/div>\n

\n

\u25cf Decommissioning Support Facilities<\/h3>\n

UK decommissioning sites including Sellafield and Magnox stations require clean instrument air for remote handling equipment, glove box ventilation control, waste treatment plant valves, and safety-related isolation systems. These applications share the same zero-contamination requirements as operational reactor instrument air, often in physically challenging legacy environments.<\/p>\n<\/div>\n

\n

\u25cf Small Modular Reactors (SMR)<\/h3>\n

The UK SMR programme \u2014 with designs including Rolls-Royce SMR under Generic Design Assessment \u2014 places a premium on compact, pre-qualified utility packages. Our modular oil-free screw compressor skids are specifically configured for space-constrained SMR plant rooms, with dual-train designs fitting within standard ISO container envelopes to support modular factory build and rapid site deployment.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n

Meydan Okuma<\/h3>\n

The Hinkley Point C (HPC) project \u2014 the UK’s first new nuclear power station in a generation \u2014 demanded instrument air compressor packages that met EDF’s stringent nuclear quality assurance requirements under French RCC-E standards, UK ONR regulatory expectations, and the specific seismic profile of the Somerset coastline site. The supply contractor, working through a Tier 1 mechanical and electrical systems integrator, required fully pre-qualified, dual-train oil-free screw compressor packages with a complete equipment qualification dossier traceable to IEEE 344 seismic testing and ISO 8573-1 Class 0 air quality verification. Lead time constraints linked to the civil construction programme meant that early ordering and phased factory inspection were non-negotiable.<\/p>\n

Ever Power’s Solution<\/h3>\n

Ever Power supplied twelve oil-free screw air compressor units in six dual-train packages, each rated at 110 kW with dual 1,600-litre receiver vessels and integrated refrigeration drying systems with -40\u00b0C pressure dew point capability. All twelve machines were subjected to a four-stage inspection programme covering in-process material verification, sub-assembly inspection, complete factory acceptance testing (FAT) witnessed by the client’s nuclear quality inspector, and final documentation review against the project’s Approved Vendor List (AVL) requirements. Seismic qualification was demonstrated via tri-axial shake table testing at an accredited laboratory, with test reports incorporated into each unit’s equipment qualification record (EQR). The complete documentation package \u2014 including 47 separate quality records per unit \u2014 was delivered to the client’s document management system in both PDF and structured XML format to integrate with the project’s Primavera-based commissioning programme.<\/p>\n

Outcome<\/h3>\n

All twelve units passed first-time acceptance inspections with zero non-conformance reports (NCRs) issued against the oil-free compression equipment. The project team recognised this as one of the few major mechanical packages on the HPC programme to achieve zero NCR status through factory inspection, and has engaged Ever Power for discussions on Sizewell C instrument air equipment qualification, currently in pre-FEED development. The delivery model \u2014 including witnessed FAT, phased inspection, and structured QA documentation \u2014 is now cited within the client organisation’s specification template for instrument air equipment on future UK nuclear new build projects.<\/p>\n<\/div>\n<\/div>\n

The quality of the documentation package from Ever Power was exceptional \u2014 and in nuclear procurement, documentation quality is often the limiting factor on schedule. Having zero NCRs through FAT on a safety-class mechanical package is genuinely rare. We have recommended them to other contractors on this programme.<\/p>\n

We specified Ever Power oil-free screw compressors for our Sellafield legacy pond drainage project instrument air system. The units had to fit into a constrained existing plant room with very limited crane access, and the Ever Power team redesigned the skid layout three times to accommodate our civil constraints without impacting the qualification basis. That kind of flexibility is not something you find from every supplier in this sector.<\/p>\n

Built to Your Nuclear Specification \u2014 Not Adapted from a Catalogue<\/h2>\n

Every nuclear instrument air compressor package we deliver begins with a blank sheet and your technical specification. Nuclear procurement is not a commodity purchasing exercise \u2014 it is a qualification activity, and our factory is structured accordingly. We operate a nuclear-dedicated quality management system aligned to ISO 9001:2015 and IAEA QA requirements, with documented design control procedures, change control, and concession management processes that satisfy both regulatory expectations and client procurement hold-point requirements.<\/p>\n

Our custom engineering capabilities span the full scope of nuclear instrument air system requirements. Skid dimensions can be tailored to existing plant room layouts, including non-standard footprints dictated by legacy buildings or modular SMR plant rooms. Inlet and outlet connection positions are freely specifiable \u2014 a detail that appears minor but is consistently one of the most time-consuming installation interface issues on nuclear projects when compressors are procured from standard ranges. Material upgrades are available at component level, including full stainless-steel air paths, titanium heat exchanger plates, and ceramic-coated rotor housings for high-humidity tropical deployment. Electrical supply configurations span 380 V to 690 V, 50 Hz or 60 Hz, with motor insulation class H as standard and Class F\/B available where thermal headroom is limited. Control philosophy \u2014 from local standalone PLC to fully integrated plant DCS I\/O \u2014 is adapted to client specification rather than treated as a supplier decision. Our engineering team has produced custom designs for Class 1E and non-Class 1E boundary separation, ATEX Zone 2 environments in legacy plants, and outdoor weather-protected enclosures with heating and trace elements for exposed northern UK locations.<\/p>\n

Supporting Britain’s Nuclear Energy Ambitions<\/h2>\n

The United Kingdom is in the midst of a generational re-commitment to nuclear energy. The British Energy Security Strategy published in April 2022 set a target of up to 24 GW of nuclear capacity by 2050, representing a near-quadrupling of the current installed base. That ambition is being pursued on multiple fronts simultaneously: the construction of Hinkley Point C in Somerset, the development of Sizewell C on the Suffolk coast, the UK SMR programme led by Rolls-Royce and others through the government’s \u00a3210 million investment, and the ongoing nuclear decommissioning programme managed by the Nuclear Decommissioning Authority (NDA) at sites including Sellafield, Bradwell, Dungeness, Oldbury, Wylfa, and Hunterston. Every one of these programmes requires nuclear-grade instrument air infrastructure at some point in its lifecycle \u2014 whether during commissioning, operation, or decommissioning.<\/p>\n

Ever Power’s UK nuclear supply chain experience spans all of these project categories. We are familiar with the procurement practices of EDF Energy’s NNB Generation Company, the supply chain strategies of the major Tier 1 contractors on HPC (including Jacobs, Cavendish Nuclear, and Altrad), and the document management and supplier surveillance requirements of the Nuclear Decommissioning Authority and its Site Licence Companies. Our documentation packages are formatted to UK nuclear industry good practice guidance, including the expectations set out in ONR’s nuclear safety technical assessment guides (TAGs) and the relevant parts of IAEA safety standards series NS-G-1.4 on instrumentation and control systems. We understand that in the UK nuclear sector, supplying equipment is only part of the task \u2014 the ability to support the client’s regulatory submissions with traceable, defensible technical documentation is what separates a capable supplier from a preferred one.<\/p>\n

For companies engaged in UK nuclear supply chain development \u2014 particularly those working on advanced technology reactors (ATR) or future Gen IV designs \u2014 we are available for pre-FEED consultations on instrument air system architecture, compressor technology selection, and qualification strategy. Engaging with equipment suppliers at the pre-FEED stage is consistently one of the most cost-effective risk reduction activities available to UK nuclear project teams, and our applications engineers are experienced in working within the structured review processes of the Generic Design Assessment (GDA) programme.<\/p>\n<\/div>\n<\/div>\n

For UK nuclear new build projects such as Hinkley Point C in Somerset or Sizewell C in Suffolk, suppliers must demonstrate compliance with the project’s Approved Vendor List (AVL) requirements, which typically include ISO 9001:2015 quality management system certification, nuclear-specific QA capability (aligned to IAEA QA requirements and RCC-E or IEEE 603 as applicable), and the ability to produce a complete Equipment Qualification Record (EQR) to IEEE 344 \/ IEC 60980 for seismic qualification. Ever Power has completed nuclear supply chain qualification for EPR-type projects and can provide pre-qualification documentation packages for AVL application. Please send your project specification to our team via the contact link on this page.<\/p>\n<\/div>\n<\/div>\n
