Subject:
IE Bulletin No. 80-10, Contamination of Nonradioactive System and Resulting Potential for Unmonitored, Uncontrolled Release to Environment R. E. Ginna Nuclear Power Plant, Unit 41 Docket No. 50-244
Dear Mr. Grier:
In response to Inspection and Enforcement Bulletin 80-10 dated May 6, 1980, concerning nonradioactive systems becoming radioactive through interfaces with radioactive systems, a review of systems that are considered nonradioactive has been performed.
This has shown that these systems are designed to prevent contamination from leakage, valving errors or other operating conditions.
Steam from the Auxiliary Boiler (House Heating Boiler) is used for two functions in controlled areas; heating and process heat.
The heating system is maintained under pressure, both as steam and condensate, until it returns to a clean area.
Therefore, any leakage would be out-leakage.
Steam for process heating is also under pressure until returned to a clean area.
An intermediate hot water heat exchanger is used between the Waste Evaporator, and the process steam used for eductors is condensed and treated as waste water.
Process steam to heat the Boric Acid Batch Tank and Boric Acid Evaporator is maintained under pressure during and after use.
Therefore, all process steam is either buffered or under pressure which prevents contamination.
/'emineralized water, instrument air and service air systems are designed to discharge in controlled areas.
There is no return path avail-able.
There are no sanitary waste facilities in controlled areas.
Steam Generators are monitored via the Steam Generator Blowdown Monitor and SOOV180/ //-
ROCHESTER GAS AND ELECTRIC DATE June 24, 1980 Mr. Boyce H. Goer, Director SHEET NO.
2 the Air Ejector Monitor.
The Secondary Water Cleanup System Waste is monitored prior to release.
Based on this review, we believe no additional sampling or moni-toring program need be established.
Very truly yours, L. D. White, Jr.
