The Sacramento Municipal Utility District has received your letter of May 5, 1982, requesting information on implementation dates for certain NUREG 0737 items.
The following table provides the District commitments for those items for which a reply was requested in your letter:
ITEM COMMITMENT I.A.I.3.1 The District has established administrative procedures Limit overtime to limit overtime which we feel are in agreement with NUREG 0737 and the NRC policy statement issued by Generic Letter No. 82-02.
You fous. Our overtime restrictions to be acceptable previously by letter dated December 10, 1981.
I.A.l.3.2 As discussed previously by letter dated November 3, Minimum Shift Crew 1980, the District will be unable to meet your recommended staffing levels until approximately 1985.
This prediction is subject to change since it is based on a specific attrition rate, as discussed in our November 3, 1980, letter.
We feel, that the total number of licensed operators at Rancho Seco is adequate in the interim and feel it is important to note that part of the problem in meeting your shift staffing levels is due to our switch to six rather than five operating crews.
