## Summary

Sellafield Limited, located in Warrington, UK, is undertaking a procurement process for "Radiation Tolerant Sensors" with an emphasis on the nuclear industry. The procurement, utilizing a direct award method, has reached the award stage as of 8th July 2026. Turck Banner Ltd has been appointed as the supplier for this contract, which involves the provision of sensors capable of operating in radiation-exposed environments essential to nuclear operations. The contract, valued at approximately £587,016 gross, encompasses the supply of 1,224 sensors meeting stringent performance standards. The contract period is set to commence on 20th July 2026 and conclude by 31st March 2027, with the delivery scheduled for the region of UKD11, United Kingdom.

This tender offers significant opportunities for businesses specializing in high-performance manufacturing, particularly those with expertise in sensor technology and semi-conductor components. The emphasis on procedural safety, asset reliability, and operational assurance within the nuclear sector underscores the demand for advanced, durable product solutions. SMEs with experience in producing reliable sensors with strict radiation tolerance specifications, particularly those with a capability to engage in technical assessments, are well placed to benefit from such procurement projects. Additionally, the procurement reinforces the need for suppliers who can innovate and create tailored outcomes to meet specific public sector needs, promoting prospective growth and development within the targeted industry.

## Notice

The Authority has a requirement for sensors that are capable of operating safely and reliably within defined radiation exposed environments associated with nuclear operations. The requirement is driven by: Nuclear safety and operational assurance Asset integrity and reliability The need for predictable performance under radiation exposure The Authority's need is outcome based and does not specify any particular manufacturer, brand, or proprietary solution. The Authority requires devices that have been independently tested to exceed a Dose of 1 x 106 Gray. The estimated requirement is for 1,224 Sensors with: 18mm diameter sensor - 18mm threaded barrel, to be supplied with 2 off M18 x 1mm locknuts Flush fitting NAMUR two wire Inductive Sensor - DC 2-wire, nom. 8.2 VDC, Output acc. to EN 60947-5-6 (NAMUR) Nominal Switching Distance 5mm - 10mm Sensor head length - Not to exceed 65mm Fitted electrical Lead (Not M12 connector) - Minimum lead length of 2 metres ATEX category II 1 G, Ex zone 0 ATEX category II 1 D, Ex zone 20 SIL2 (Low Demand Mode) acc. to IEC 61508, PL c acc. to ISO 13849-1 with HFT0 SIL3 (All Demand Mode) acc. to IEC 61508, PL e acc. to ISO 13849-1 with redundant configuration HFT1 Protection Class IP67 The Authority requires that supplied sensors are to contain Semi-Conductor (SMD/SMT) devices from the same Semi-Conductor Component Manufacture production batch. An Initial Sensor manufacturing batch of a minimum of 11 Sensors is required to allow for Sellafield Limited initiated Third Party Radiation Tolerance Testing. The remaining Semi-Conductor devices (the same Reel) are to be retained awaiting the conclusion of the Third Party Radiation Tolerance Testing. On conclusion of Radiation Tolerance Testing, if Sellafield Limited deem the sensors to be acceptable, the balance of stated Order Total are to be manufactured from the same SMD/SMT component Reel as those sensors manufactured for the purpose of the test (>=11 sensors). If, the first batch (11 off) sensors are not acceptable to Sellafield limited, a further 11 off sensors are to be produced to allow for repeat Radiation Tolerance Testing, the semi-conductor component requirements remain as above. The Sensor Manufacturer is to create a specific product Part Number for the Authority. Sellafield Ltd Quality Grade 04 for sensors produced for testing purposes, Quality Grade 03 for all other supplied sensors.
