Docket Nos. 50-280 and 50-281 Mr. D. s. Cruden Vice President - Nuclear Virginia Electric and Power Company Post Office Box 26666 Richmond, Virginia 23261
Dear Mr. Cruden:
June 2, 1988 *
SUBJECT:
ENVIRONMENTAL QUALIFICATION OF CONTAINMENT PENETRATIONS AT SURRY UNITS 1 AND 2 During a Region III Environmental Qualification (EQ) Inspection at the Braidwood Station conducted during February and March 1988, it was determined that the environmental qualification of four Bunker Ramo containment pene-tration assemblies had not been adequately demonstrated.
In response to a recent request, you provided information regarding the verification of qualification for Amphenol penetration assemblies installed at Surry which may be identical to the Bunker Ramo penetrations. After reviewing this information we conclude that environmental qualification has still not been demonstrated for these assemblies.
The documentation (test reports) used to support your position that these penetration assemblies are qualified is similar to that used for Braidwood 2. That documentation did not provide sufficient information (for example, insulation resistance test data) to conclude that operability under design basis events has been fully demon-strated.

\\
,- 'Since EQ has not yet been established for the subject penetrations installed at Surry, \\you should follow the guidance identified in Generic Letter 88-07, 11 Environme'ntal Qualification of Electrical Equipment Important to Safety for Nuclear Power Plants, 11 dated April 7, 1988, regarding written Justification for Continued Operation.
This letter does not require any response. However, your evaluation in support of making a finding of operability should be made available for NRC review regarding the demonstration of equipment operability.
Sincerely, Ortg tna l S i'gned by Bruce A. Boger for~
