In Duke Power Company document, "Regulatory Guide 1.97, Revision 2 - Review for Oconee Nuclear Station," transmitted September 28, 1984, they committed to comply with Regulatory Guide 1.97, "Instrumentation for Light-Water-Cooled Nuclear Power Plants to Assess Plant Environs Conditions during and following an accident", unless specific exceptions were described.
Page 5-7 of the Oconee review document states, "dedicated control board displays for the instruments designated as Types A, B and C, Category 1 or 2 and qualified for use throughout all phases of an accident will be specifically identified on the control panels so that the operator can discern that they are available for use under accident conditions."
Page 5-6 of the Oconee review document states, "recording of instrumentation readout information is provided for at least one of the redundant channels."
It also states, "the trend or transient information will be available on dedicated recorders or stored in computer memory for display on demand."
Page 5-8 of. the Oconee review document states, "servicing, testing, and calibration programs are specified to maintain the capability of the monitoring instrumentation."
These statements and commitments are consistent with the requirements of Regulatory Guide 1.97.
Contrary to the above:
(a) Dedicated control board displays for the instruments designated as Types A, B, and C, Category 1 or 2 were not specifically identified:

- 1.
RCS hot leg water temperature
- 2. Auxiliary feedwater flow
- 3. Steam generator level
- 4. Degrees of subcooling (c) The inverter output voltmeters [defined as Type D, Category 2 in the RG] were not included in the-calibration program, and had not been calibrated since the original construction of the units according to records.
The Deviation applies to Units 1, 2 and 3.
Please provide to the U.S. Nuclear Regulatory Commission, ATTN:
