Unit No. 1) )

APPLICATION FOR AMENDMENT TO OPERATING LICENSE Pursuant to Section 50.90 of the regulations of the Nuclear Regulatory Commission, Niagara Mohawk Power Corporation, holder of Facility Operating License No. DPR-63, hereby requests that Section 3.2.3 of the Technical Specifications set forth in Appendix A to that License be amended. ,This proposed change has been approved by Site Operations Review Committee and Safety Review and Audit Board.

The proposed Technical Specification change is set forth in Attachment A to this application. A safety evaluation, which demon-strates that the proposed change does not involve a significant hazards consideration, is set forth in Attachment B. The proposed change would not authorize any change in the types or any increase in the amounts of effluents or any change in the authorized power level of the facility.

License No. DPR-63 Docket 50-220 Su ortin Information The proposed change included in Attachment A, represents a clarification of the reactor coolant chemistry specifications. Its

'urpose is to provide for shut-down conditions, in accordance with

, the intent of those specifications.

When reactor steaming rates are less than 100,000 pounds per hour, present Technical Specifications limit the chloride ion concen-tration to 0.1 ppm. This specification is intended to restrict chloride content during periods of operation such as reactor start-up and hot stand-by when reactor water dissolved oxygen levels may be high.

During normal operation, when steaming rates are greater than 100,000 pounds per hour, boiling occurs causing deaeration. This re-sults in much lower dissolved oxygen levels (0.2-0.3 ppm). At these low oxygen levels, chloride levels of up to 1 ppm can be tolerated without encountering any damage to the primary system materials.

In the process of shutting down, however, the reactor may be brought to a steaming rate of less than 100,000 pounds per hour while the chloride content is greater than 0.1 ppm and oxygen content is low.

The oxygen content remains low until the reactor temperature drops and the head vent is opened. Therefore, tho extension of normal operation chloride limits to shutdown conditions would not pose any problems to the primary system materials.
