Unit One 47 Gentlemen:
The Sacramento Municipal Utility District received from you on December 28, 1977, a twenty-two page questionnaire concerning Diesel Generator Units. Plaase find attached our reply per your request and additional information including our inspection procedures.
We consider this reply closes out your request.
The data not included in the questionnaire is either not readily available or would require unorthodox testing of the units to obtain the information requested.
If you have any questions concerning information contained in this reply please contact Mr. R. Colombo at the Rancho Seco Nuclear Station.
Respectfully submitted, s
J. J. Mattimoe Assistant General Manag and Chief Engineer JJM:RWC: sal.
