1 By letter dated March 19, 1993, the Northeast Nuclear Energy Company proposed changes to the Millstone 3 technical specifications in response to Generic letter 90-06. The licensee did not adopt the staff position for GI 70.
Rather, they proposed an alternative to the staff suggested technical l
specifications.
The staff has not yet reached a conclusion as to the acceptability of the licensee's position on GI 70.
The proposed technical specifications addressing GI 70 will be dealt with at a later time. The licensee also proposed changes describing the reactor coolant system vent paths, which the staff has not yet reviewed. This evaluation will address only the changes related to GI 94.
The actions proposed by the NRC staff to improve the availability of the low-
[
temperature overpressure protection (LTOP) system represents a substantial increase in the overall protection of the public health and safety and a determination has been made that the attendant costs are justified in view of this increased protection.
The technical findings and the regulatory analysis related to Generic Issue 94 are discussed in NUREG-1326, " Regulatory Analysis for the Resolution of Generic Issue 94, Additional Low-Temperature Overpressure Protection for Light-Water Reactors."
The proposed changes to the Millstone 3 technical specifications in the licensee's letter of March 19, 1993, are consistent with that proposed in the staff's generic letter. The proposed modifications to the technical specifications involves plant operation in Modes 5 or 6 with an inoperable LTOP channel.
The licensee has adopted the staff position in that operations under such conditions be limited to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> before restoring the LTOP channel to operable status.

The staff has reviewed the licensee's proposed modifications to the Millstone 3 technical specifications. Since the proposed modifications are consistent with the staff's position previously stated in the generic letter and justified in the above mentioned regulatory analysis, the staff finds the proposed modifications to be acceptable.
3.0 STATE CONSULTATION
l In accordance with the Commission's regulations, the Connecticut State official was notified of the proposed issuance of the amendment. The State i
official had no comments.

4.0 ENVIRONMENTAL CONSIDERATION
The amendment changes a requirement with respect to installation or use of a facility component located within the restricted area as defined in 10 CFR Part 20 and changes surveillance requirements. The NRC staff has determined l
that the amendment involves no significant increase in the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in individual or cumulative occupational radiation exposure. The Commission has previously issued a proposed finding that the amendment involves no significant hazards l
