| Title | Part 21 Report - Interim Report for Eaton TRM5 Timing Relays |
| Event Description | The following is a summary of information provided by the Curtiss-Wright Nuclear Division via email:
QualTech NP discovered the presence of a programmable logic device (a flash-based CMOS (complementary metal-oxide-semiconductor) microcontroller) in the timing relays that was not previously identified for this family of relays. The only affected facility is Perry Nuclear Plant. This could potentially lead to unevaluated electromagnetic interference or radiofrequency interference issues when installed in the plant. For questions concerning this potential 10 CFR 21 issue, please contact: Tim Franchuk Quality Assurance Director QualTech NP, Curtiss-Wright Nuclear Division (513) 528-7900, ext. 176
QualTech NP provided an update identifying other facilities that are affected by the Eaton TMR5 timing relays. The other affected facilities are Calvert Cliffs, Beaver Valley, Diablo Canyon, Arkansas Nuclear One, and Comanche Peak. Notified R1DO (Cahill), R4DO (Gaddy), R3DO (Szwarc) via phone and the Part 21 group via email. |
