Dear Sir:
This letter is in respense to your report, Reference 2, concerning two infractions repor'ed by your inspecter.
c Infraction No. 1 Technical Specification D.1 states in part that:
"All plant operations which have a significant direct or potential effect on the reactor and its auxiliary systems shall be conducted in accordance with written procedures..."
Procedurc OP-4201, Rev. 5, " Power Range Channel Calibration," prescribes the specific method of calibrating the power range channels during periods of steady state power operation and states in part:
"The power range neutron flux level channel amplifiers will be adjusted on each shif t to agree with the primary plant thermal energy balance..."
Contrary to the above, the power range neutren flux level channel amplifiers were adjusted in a nonconservative direction with regard to the existing thermal energy balance, and without adherence to the requirements of OP-4201.
Response No. 1 As described on page 10 of the reference inspection report corrective action was performed prior to ccepletion of the inspection, and accordingly
