Dear Mr. Reid:
( w' i N'
In your letter of February 18, 1976, you requested that SMUD g
provide the NRC with information on how the District intended to mee% e j#
requirements of Paragraph 50.34a. The purpose of this letter is to..
N falls into the category of plants for which application was filed p[ffbr@go#
comply with the request for a 30-day response. Rancho Seco Unit No.L.
-p adopting a design which encompassed the basic "as low as prac to January 2,1971.
In 1968, the District took an industry lead ro ;
M concept.
Rancho Seco's liquid radwaste system was designed for " rec with no liquid discharge from the plant during normal operation. The
,('.
inherent operating characteristics of PWR's along with a designed waste 3/
gas hold-up capability of a 45-day minimum was another example of the adoption of the basic ALAP concept.
It should also be noted that the operating limits in the Rancho Seco Unit No.1 Technical Specifications have as their basis numbers comparable to those found in Appendix I to 10 CFR, Part 50.
So as to provide the NRC with the information it needs to determine whether Rancho Seco Unit No.1 should be treated in a manner similar to later plants, the District is presently engaged in a detailed study which will give all that information outlined in Enclosures 1 and 2 to the NRC's letter of February 18, 1976. The District will make every reasonable attempt to comply with the NRC's present schedule.
- However, i
it should be recognized that meeting the June 4,1976 deadline will be difficult due to the delay in the arrival of the specific guidelines necessary to define the scope of the study.
Sincerely yours, e, M ~ff O A e
