ACTION IT£115

TECHNICAL WORKING CROUP

1100 6/5/79

1. Prepare recommendation as to operation of door (Aux./P.H. Bldg.) in conjunction with supply fans and coordinate test requirements.

2. Investigate the causes of the increase in radiation levels ns water was transferred from the Aux. Bldg. Sump to the concentrate waste tank. Should this be expected in future waste management liquid movements?

3. Confirm discrepancies in containcent water level for action directive on use of coolers for negative reactor building pressure.

4. Leave RR coolers secured until containQent water level is confirmed.

5. Provide assessment of integrated reactor building equipment list as to priority and frequency of meggar readings.

6. Provide decision heights based on electrical equipment list and critical components and systems.

7. Verify chloride - readings in "A" Bleed Tank Sample of 6/7.

8. Recommendation and action as to increasing PH based on sample results and B&W recommendation.

9 . Conduct review of piping systems interfacing between the r~s and various support systems to identify positive methods of determining transfer of highly contaminated RCS to lesser contaminated or clean systems.

10. Redo Steam By-Pass Valve position curve over time to indicate "%Demand Signal vs . Time" . No further valve action is to be taken until new curve is published.

11. Proceed with transfer of approximately 300 gallon from lower to upper tanks in Tank Farm.
