LICENSEE EVENT REPORT 80-014, UPDATE REPORT
- 1. Cause Description ~and Analysis:
On July 2,1980, as a res ult of taformation obtained by Carolina Power and Light Company from Crouse Hinds (manufacturer'of Robinson-2
, Containment Vessel (CV) electrica. penetrations) .it was determined l that no certification of qualification is available for the electric cable " pigtails" used in the manufacture of CV penetratio'ns (C.H.
Catalog No. 0100759). This type penetration contains two (2) and four (4) conductor AWG No.16 shielded cable and is used for instrumentation on saf ety related equipment. The instruments involved .
which would be required in. the event of a design basis accident and their required operating times following the accident are as follows:
Pressurizer Pressure 30 Minutes Pressurizer Level' (No ESF Function) 30 Minutes Steam Generator Level 24 Hours Steam Line Flow 24 Hours
- 2. Corrective Action:
A program was implemented to test and qualify samples of the
. penetration pigtails. These tests have certified that the cable pigtails are qualified to the accident conditions described in the H. B. Robinson FSAR.
In addition, information from Crouse Hinds revealed that material documentation could not be located uon one of two penetrations built '
for Robinson as Catalog No. 0100747. This type penetration has three conductor cables of AWG No. 9 and is used primarily to power small 480 volt motors. One of these penetrations is in train A and the other in train B. One penetration is fully documented and qualified and the other penetration _ has been inspected to verify that it is of the same composition and construction. There fore, the penetration is believed to be adequate and no further actions are required.
- 3. Corrective Action'To ' Prevent Purther' Occurrence:
Since it was a thorough review of the environmental qualifications of electrical equipment at Robinson Plant which resulted in this report, further additional corrective action is not considered necessary at this time.
