I Amendment 3 A15-1 l
Docket 50-312 Amendment Na, 2 April 15, 1968 s
QUESTION Identify those items that will eventually be classified as 15A.1 technical specifications that now affect plant design.
Examples (DRL 15.1) include the minimum conditions of operation on:
engineered safety features; emergency generators; and in-core flux monitors.
ANSWER The plant design is influenced mainly by the 70 General Criteria for Nuclear Power Plant Construction Permits, together with con-siderations of performance objectives. Generally, the technical specifications refer to the implementation of many or all of these criteria. However, it is possible to anticipate some spec-ifications which also dictate the design rather than result from limitations of the design.
The most significant of the former ca tagory are listed below.
