1 ENCLOSURE SAFETY EVALUATION MILLSTONE NUCLEAR POWER STATION, UNIT 3 l
i INTRODUCTION i
By letter dated August 15, 1983, Northeast Nuclear Energy Company (NNECO),
i the lead applicant and operating agent of the Millstone Nuclear Power Station, i
Unit 3 (M111 stone-3), requested an amendment to its Construction Permit CPPR-113, to transfer ownership shares in M111 stone-3 as follows:
Ownership Interest From To to be Transferred The Connecticut Light Vermont Electric Generation 0.0375% (0.431 NW) and Power Company and Transmission Cooperative, Inc.
t Western Massachusetts Vermont Electric Generation 0.1125% (1.294 MW)
Electric Company and Transmission Cooperative, Inc.
The NRC staff has completed its review of all safety-significant matters related to the issuance of the construction permit amendment as requested in the August 15, 1983 application. This Safety Evaluation is issued in support of Amendment No.11 to Construction Permit CPPR-113, approving the transfer of ownership shares in M111 stone-3 as stated above. Table 1 delineates the owners and their corresponding shares, assuming that all transactions as approved in this amendment and any prior to this amendment, with the exception of Amendment No. 8, have taken place. Amendment No. 8 to CPPR-113 authorized purchase of 0.600% ownership shares by Vermont Electric l
Generation and Transmission Cooperative Inc. ("VEG&T") as well as purchase of c
i ownership shares by Massachusetts-Municipal Wholesale Electric Cooperative, ("NMWEC")
l Vermont Public Power Supply Authority, ("WPSA") and Washington Electric Cooperative Inc. ("WEC"). However in its letter of August 15, 1983 the applicant informed the NRC staff that HHWEC, VPPSA and WEC decided not to consummate their respective i
purchases authorized thereunder. Therefore Amendment No.11 reduces the ownership
~
i share in Millstone-3 to be transferred from CL&P and WMEC0 to VEG&T from 0.600%
l (6.90 MW) as authorized in Amendment No. 8 to CPPR-113 to 0.150% (1.725 MW).
It should be noted that on June 30, 1982, The Hartford Electric Light Company
("HELC0"), formerly a lead participant in M111 stone-3, merged with and into its affiliate, Connecticut Light & Power Company ("CL&P"). On that date CL&P succeeded to all of the rights and obligations with respect to HELCO's 18.2001 ownership interest in the Unit. Consequently, CL&P will own a 52.6125% interest in the Millstone Unit No. 3 upon completion of all transactions approved in this and prior amendments.

The purpose of the Safety Evaluation is to examine the impact of the proposed I
change in ownership shares as described above on the conclusions presented in Section 21.0 of the " Safety Evauation of the Millstone Point Nuclear Power Station, Unit No. 3." (Construction Permit Stage) issued March 13, 1974.
Specifically, the evaluation addresses the resultant changes or lack of changes in the following:
1.
The design of the facility or requirements for safety-related information, i
and 2.
The conclusions concerning the health and safety of the public.
EVALUATION We have reviewed NNECO's application for a construction permit amendment as identified above. Our review of safety-related matters and our conclusions concerning each item are described in the following subsections of the evaluation report.
Design of the Facility We have reviewed the application for amendment submitted by the letter of August 15, 1983, and find no information which leads us to conclude that the requested amendnent to the construction permit will result in design changes to the facility. We note that the letter states that the transfers proposed "will in no way affect the operation and control of the Hillstone Unit No.
l 3 project by the lead participants," "will not endanger the health or safety omer>

. of the public,"and "does not involve any significant increase in the probability of an accident, any significant increase in the consequences of an accident, or any significant decrease in the safety margin." On the basis of our review of the application for amendment and the above statements by flNECO, we conclude that the proposed transfer of ownership interests as stated will not result in safety-significant design changes to the facility.
Further, we find that our conclusions in Section 21.0 of the Safety Evaluation Report (Construction Permit Stage) for flillstone-3 will not be altered by the issuance of the requested amendment to the construction permit.
Health and Safety of the Public Uased on our conclusion that the proposed transfer of ownership interests will not result in safety-significant design changes to the f acility, we further conclude that there will be no impact on the health and safety of the public as the proposed transfer does not involve any significant increase in the probability of an accident, any significant increase in the consequences of an accident, does not create the possibility of an accident of a type different from any evaluated previously and does not involve any significant decrease in the safety margin. Our conclusions in Section 21.0 of the Millstone-3 Safety Evaluation Report (Construction Permit Stage) regarding the health and safety of the public will remain unaltered.
C0hCLUSI0llS We have examined the impact on safety considerations of amending Construction Permit CPPR-ll3 to permit the transfer of ownership interests in ll111 stone-3.
We have concluded that the re~ quested amendment will not result in safety-significant design changes to the facility.
On the basis of the above conclusion, we find that the issuance of the requested amendment approving the transfer of ownership interests to the electric utilities as previously stated will not be inimical to the health and safety of the public, and that our conclusions in Section 21.0 of the Millstone-3 Safety Evaluation Report (Construction Permit Stage) will remain unaltered. Further, we have concluded, based on the considerations discussed above, that:
(1) because the amendnent does not involve a significant increase in the probability or conseq-uences of accidents previously considered, does not create the possibility of an accident of a type different from any evaluated previously and does not involve a significant decrease in a safety margin, the amendment does not involve a significant hazards consideration, (2) there is reasonable assurance that the omce >
