GE Hitachi Nuclear Energy July 23, 2014 MFN 14-010 R1 U.S. Nuclear Regulatory Commission Attn: Document Control Desk Washington, DC 20555-0001
Subject:
Completed Evaluation of Part 21 Potentially Reportable Condition Notification:
Unseating of Valve Spring on SSPV This letter provides information concerning an evaluation now completed by GE Hitachi Nuclear Energy (GEH) regarding the malfunction of Scram Solenoid Pilot Valves (SSPVs), which have been observed to impair control rod scram performance. As stated herein, GEH has concluded this condition is Not Reportable for two of the affected plants (Enrico Fermi 2 and Columbia Generating Station plants), but GEH does not have sufficient information to fully evaluate the safety significance of the condition for the remainder of the potentially affected plants. Given that, GEH closes this 10 CFR Part 21 evaluation with a Transfer of Information to potentially affected licensees, in accordance with the requirements of 10 CFR 21.21(b) and will communicate the determination of Not Reportable to the identified plants where sufficient information was available to make that determination.
Although the Enrico Fermi 2 and Columbia Generating Station plants are included in the attached list of U.S. plants potentially affected, inspections of all suspect SSPVs remaining at those plants indicate that no other SSPVs at those plants exhibit the condition (as informally reported to GEH),
and therefore those plants were determined to not have a reportable condition.
This letter closes the supplemental 60-Day Interim Report Notification (MFN 14-010 R0), provided on March 13, 2014, per 10 CFR 21.21(a)(2).
If you have any questions, please call me at (910) 819-4491.
Sincerely, Dale E. Porter Safety Evaluation Program Manager GE-Hitachi Nuclear Energy Americas LLC Dale E. Porter GE-Hitachi Nuclear Energy Americas LLC Safety Evaluation Program Manager 3901 Castle Hayne Rd.,
