Supporting Information for Correction of Accumulator Borated Water Volume (SR 3.5.1.2)

Rochester Gas & Electric Corporation R.E. Ginna Nuclear Power Plant Docket No. 50-244

Reference:

Letter from R.C. Mecredy, RG&E, to G.S. Vissing, NRC,

Subject:

Application for Amendment to Facility Operating License, Correction ofAccumulator Borated 8'ater Volume (SR 3.5.1.2), dated August 19, 1997.

Dear Mr. Vissing,

Per your request, enclosed are four documents related to the accumulator water volume. A brief description of each document is provided below:

1. Gilbert Associates Inc., Drawing B-308-633, - This drawing shows the physical layout of Accumulator A and its two level transmitters (LT-938 and LT-939).

2. Gilbert Associates Inc., Drawing B-308-634, - This drawing shows the physical layout of Accumulator A and its two level transmitters (LT-934 and LT-935).

Ginna Station Procedure CPI-LVL-934, Calibration of SI Accumulator B Level Loop 934, Revision 4, pages 1, 28, and 29 only - This procedure shows: (1) how accumulator LT-934 transmits to the main control board, and (2) a detailed drawing of the vertical piping from the accumulator which the level transmitter is connected to.

The level transmitter is actually only measuring the level over a 14n span in this vertical pipe which corresponds to a 0 - 100% level span (e.g., 7" equals 50% level as required by technical specifications). This procedure is typical for all four level transmitters.
