NRC INFORMATION NOTICE NO. 90-18: POTENTIAL PROBLEMS WITH CROSBY SAFETY

RELIEF VALVES USED ON DIESEL GENERATOR

AIR START RECEIVER TANKS

Addressees

All holders of operating licenses or construction permits for nuclear power

reactors.

Purpose

This information notice is intended to alert addressees to potential problems

with Crosby safety relief valves that could result in a loss of starting'alt

to the emergency diesel generators (EDGs). It is expected that'recipients

will review the information for applicability to their facilities and consider

actions, as appropriate, to avoid similar problems. However, suggestions

contained in this Information notice do not constitute NRC requirements'

therefore, no specific action or written response is required.

Description of Circumstances

On March 13, 1989, Cooper Industries was made aware of circumstances at Perry

Unit 1 that led to the Division I EDG being declared inoperable. A Crosby

safety relief valve on'one of the two EDG starting air receiving tanks was

inadvertently hit during maintenance activities. The force of the impact

caused the valve to open and blow down both air receiving tanks. The safety

relief valve did not reseat until approximately 30 psig below the EDG automatic

start lockout signal. On January 12, 1990, Cooper Industries learned that a

similar event had occurred at Comanche Peak. On January 17, 1990, Cooper

Industries'submitted a 10 CFR Part 21 report on the affected safety relief

valves (Crosby style JMBU and JRU safety relief valves).

Discussion of Safety Significance:

Although Crosby-style JMBU and JRU safety relief valves were designed to meet

the requirements of Section VIII of the ASME Boiler and Pressure Vessel Code, they were not seismically qualified. In addition, the blowdown characteristics

of the valves were not consistent with the functional requirements of the

system in which they were installed. Cooper Industries has recommended re- placing these valves with seismically-qualified valves that have the proper

blowdown reseat characteristics.

March 9, 1990 All licensees with Transamerica Delaval Inc. (TDI) diesel generators were

notified of this problem by Cooper Industries via the Part 21 notification.

However, Crosby safety relief valves (style JMBU, JRU, and possibly non-code

style JMB) may be installed on EDGs manufactured by other vendors. Licensees

may wish to verify that the relief valves installed in their EDG air start

systems have appropriate qualifications and characteristics.
