GENERAL ELECTRIC CR-120B RELAYS SUPPLIED BY NATIONAL TECHNICAL SYSTEMS FAIL BENCH TEST
"On October 31, 2011, NextEra Energy Seabrook, LLC completed a 10 CFR 21 evaluation of a condition associated with General Electric (GE)-CR-120B relays supplied by National Technical Systems, Inc. and intended for use at Seabrook. Six (6) Quality Level 1 GE-CR-120B relays failed bench testing. During bench testing, the subject relays failed to reset when de-energized. An evaluation was performed to determine the applications where these relays could have been and were installed and to determine if the failure of the subject relays could result in a Substantial Safety Hazard as defined in 10 CFR 21.3. The evaluation concluded that there is one safety significant application relative to the failure of the GE-CR-120B relays to reset in the Seabrook Diesel Air Handling System (DAH).
"Each DAH system train (includes one supply fan and one exhaust fan per train) has one relay that provides a start permissive for the ventilation fans. An analysis of the failure of a GE-CR-120B relay in the DAH system determined that, if the relays were installed, the condition could create a substantial safety hazard due to a subsequent loss of the emergency power function. Therefore, this report is being submitted pursuant to the requirements of 10 CFR 21.21(d)(3)(i). A written notification will be made to the NRC within 30 days pursuant to 10 CFR 21.21(d)(3)(ii).
"No actual safety consequences resulted from this condition because the GE-CR-120B relays were not installed in the plant in this safety significant application."
The licensee notified the NRC Resident Inspector.

PACKAGE RECEIVED WITH SURFACE CONTAMINATION ABOVE LIMITS
"Package marked container 1 from Hot Shots Nuclear Medicine (license #21-26597-01md) had a wipe test of 4700 dpm. Background was re-measured and the second wipe was 5900 dpm. The package was thoroughly wiped with alcohol. The third wipe revealed a count of 510.0 dpm. The package was then opened. An inside wipe of the package was 678 dpm. The package was considered safe for use. The doses were used. Notifications were made to personnel from Medical Physics Consultants and Hot Shots Nuclear Medicine. The Ingham Regional Medical Center Radiation Safety Officer was also notified."
The package contained Technetium-99m, a gamma emitter. The licensee believes that the package was transported via a Hot Shots Nuclear Medicine courier.
