| 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 |
