Onorations Report for February 1969

1. GITRA L Tac scheduled plant outage which was begun on October 18, 1963, was continue.1 throughout this report period. The unjor effort vms devoted to conducting the containment vessel leak rate test. The on-site Westinghouse cceputer was programmed for the test and the entiro test was run using the co putcr for the data processing.

A continuity checkout of the electrical circuits of the recirculation systea and the safety injection system modifications vms completed on February 12.

Tno reactor vessel head cladding was inspected during the month and reinsulation of the primary systm components was started on Februat;/ 24.

Preparations were made for a junk shipment of previously irradiated outr o nbly cupport tubes. The undcruater shear was checked out and two cub:.L:. ably support tubes shearod. A rmote readout, high level 041 tube wat uccJ Lo ucasure the radiatien levels.

The number two rotary device for the flux mapping instrumentation vms installed and tested.

2. OPERATIO"AL Tr$1S An integral leak rate test was conducted from February 13 to February 19 at a test pressure of 10 poig. The leakage rate was determined to be 0.129% per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> when extrapolated to 30 poig. The Technical Specifications limit at 30 psig is 0.4% of the contained volume per 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. A controlled leak rate measurment was initiated on completion of the test to verify the sensitivity and accuracy of the test.

The S!!EC fire and evacuation alarms were tested on February 7, M, 21 and 28.

The monthly test of the radiation monitoring systcm was ccupleted on February 7.

l l 3. mar:TI:A CE The principal items of mechanical maintenance during the month included cleaning the reactor vessel conoscal gasket surfaces; painting the reactor vessel head with primer paint; reinstalling the steam generator primary systm manways; inspecting number two discharge tank internals; repairing pipe and gasket leads on the deacrator; lapping the seat and repacking the letdown flow control valvo, IRC-21V) installing a new bellows and lapping the seat on pressurizer safety valve, V-373; installing new gaskets on the reactor vessel head; rcplacing the fan belts on the control room air handler; fabricating seals for UIC.and CIC detector cans; and repairing the seal on a storage well pump; and oiling the pumps in the l

containment vessel.

4. CHD:ISTRY The main oolant system was in a cold shutdown condition throughout the entire month with the core transferred to _ the fuel starage rack. The main coolant was mixed with the storage well water. A summary of the analyses perfomed on the storage well during the month is giver in the table below.
