Dear Sir:
Mr. A. Schwencer's letter dated April 23, 1980, requested that Duquesne Light Company furnish certain specified information from its files. On April 25, 1980, five NRC personnel visited the Beaver Valley site for the purpose of touring selected areas of the plant, to have discussions with licensee personnel and to review and receive data and documents which in-cluded the information requested by the aforementioned letter.
This letter identifies and documents the information and data given to the NRC personnel at that time as follows:
1.
Copies of preoperational test data related to pressures and flows in the safety injection system.
In addition, flow data resulting from a recent test of one Low Head Safety Injection pump was pro-vided.
2.
The peak centerline temperatures for each of the three high pressure safety injection flow cases evaluated in Westinghouse Owners Group Report OG-18 is not available from Duquense Light Company files.
3.
A copy of the Westinghouse recommendation letter to DLC to add a 3/4 inch relief valve to the CVCS was provided.
In addition, hanger drawings related to isometric pipe layout drawings 150-266, 267, 268, 271, 272, 274, 277 and 279 were provided.
If you have further questions, do not hesitate to contact us.
Very truly yours, l
C. N. Dunn Vice President, Operations l
