Subject:
Significant Deficiency Report No. 33 MDA Scientific, Inc. - Defective Pressure Switches in Chlorine Monitors Limerick Generating Station - Units 1 and 2 NRC Construction Permit Nos. CPPR-106, 107 Attachments:
a) Letter, MDA Scientific, Inc. to Bechtel Power Corp., July 23, 1980 b) Letter, MDA Scientific, Inc. to USNRC, July 20, 1980 c) Letter, Dwyer Instruments Inc. to MDA Scientific, Inc. July 22, 1980 File:
QUAL 2-10-2 (SDR #33)
Dear Mr. Grier:
The attachments have brought to our attention a deficiency in the subject pressure switches supplied by MDA Scientific, Inc.
as part of the Limerick Generating Station Chlorine Monitor System.
As indicated, this problem has been previously reported i
to the USNRC by the vendor under 10CFR21.
The deficiency consists of failure of the subject switches to perform in a consistent and repetitive manner, apparently due to diaphragm material problems.
We consider the deficiency described in the attachments to be a significant deficiency per 10CFR50.55(e) and are hereby notifying you as required.
