A 2,3 2-85-017 NA NA With reactor at 0.5 per cent power and turbine latched with air / oil relay cut out, the air / oil relay was cut in which caused a momentary steam flow / feed flow bistable to pick up. This coincident with low level bistable already in caused a reactor trip. The duration of the initiating signal was so short that reactor trip breaker B did not open.

Subsequent testing and discussion witis the vendor, Westinghouse, have confirmed that the reactor protection system and the trip breakers functioned properly and no anomalies exist.

r MONTHLY NARRATIVE REPORT 0F OPERATION AND MAJOR MAINTENANCE EXPERIENCE This report describes the operating and major maintenance experience for the month of November, 1985. This narrative report was prepared by the plant staff and is submitted in accordance with Section 6.9.1.7 of the Units 1 and 2 Technical Specifications.

On November 1, 1985 Unit 2 was paralleled to the grid On November 6, 1985 Unit 2 experienced a reactor trip On November 9, 1985 Unit 2 was paralleled to the grid On November 9, 1985 Unit 2 experienced a reactor trip On November 9, 1985 Unit 2 was paralleled to the grid On November 11, 1985 Unit I was paralleled to the grid after a 12 day outage On November 13,1985 Unit 2 was separated from the grid for generator testing On November 13, 1985 Unit 2 was paralleled to the grid On November 13,1985 Unit 2 experienced a reactor trip On November 15, 1985 Unit 2 was paralleled to the grid On November 18,1985 Uriit 2 reduced power to 30% to replace condensate polisher resins On November 26, 1985 Unit 2 experienced a reactor trip On November 28,1985 Unit 2 experienced a reactor trip On November 30, 1985 Unit 2 was paralleled to the grid Unit 1 operated this month with a unit availability factor of 66.6% and a unit capacity factor of 61.6%. At the start of the month, Unit I was shutdown for 10 days to clean up secondary water chemistry.

There were no major safety related maintenance activities performed for Unit 1 or Unit 2 in the month of November,1985.

No challenges to the PORVs or Steam Generator Safety Valves have been made.
