2625NS for Nuclear

Service Applications

The 2625NS volume booster uses EPDM

(ethylene‐propylene) elastomeric parts. These parts

have superior resistance to degradation at elevated

temperature and radiation levels. This version is

designed for nuclear service applications where oil‐free

supply air is available.

Both the 2625 and 2625NS are available as

safety‐related items when processed using the

commercial grade dedication section of the 10CFR50,

Appendix B, quality assurance program. 10CFR21

reporting is also part of the safety related processing

program. Seismic operability testing has been done to

qualify both versions as rigid items at levels up to 9g's

uniaxial (in each axis). Further nuclear service

qualification data is available on request.
