O HAZARDS ANALYSIS BY THE RESEARCH & PGiER REACTOR SAFETY BRA:{CH DIVISION OF LICE'iSING AND REULATION IU THE MATTER OF YANKEE ATOMIC ELECTRIC COMPANY FROPCSED CHANGE NO. 20 DOCKET NO. 50-29 Introduction P
Pursuant to the provisiens of paragraph 3.A of License No. DPR-3, as amended, Yankee Atomic Electric Connany in Proposed Change No. 20 dated March 12, 1962, recaested authorization to install two valved and blanked-off connections in the safety Injecticn System piping. It is Yankee's opinion that there is a possibility that a higher maximum reactor operating power level may be regaested and authorized at some future time. Based on their preliminary analysis of reactor accidents at this higher power level, Yankee believes that provisions should be made for future installation of an additional safety injection pump. If Proposed Change No. 20 is authorized, two valved and blanked-off connections, which would facilitate future installation of the additional safety injection pug, would be added to the Safety Injection a
System piping during the next shutdown for refueling.
Discussion R
Yankee has indicated that the valves and piping to be used in making the proposed connections will be designed, fabricated and tested in accordance with the American Standards Association Code for pressure piping. Both the piping and valves will be of stainless steel construction and should be sufficiently corrosion-resistant to withstand the conditions of service use.
Since the connections are to be blanked-off, there will be no possibility that an inadvertent operation of the valves would result in the opening of the Safety Injection Systen to the atmosphere. Accordingly, it is our i
opinion that addition of 'the connections to the Safety Injection Systen will I
have no effect on the safety of operation.
Conclusion We believe that Proposed Change No. 20 does not present significant hazards considerations not described or inplicit in the license application, as amended to June 23, 1961. We have further concluded that there is reason-able assurance that the health and safety of the public will not be endangered by operation of the facility as proposed.
