NOTES 1.

Quality Assurance is in accordance with the BVPS-2 program defined in FSAR Chapter 17.

2.

EOF and TSC indications of the BVPS-2 Post Accident Monitoring Instrumentation will be addressed in the TSC and EOF submittais.

3.

The BVPS-2 Design Basis only identified the key variables that are used for monitoring the performance of safety systems and other systems 4

normally employed for attaining a safe shutdown condition.

Per the definitions in the Design Basis, these variables are designated Type D,

)

Category 2.

The preferred backup variables to the Type D variables are not specified in this document. Since these variables are designated Type D, Category 3, the instrumentation is only required to be high quality comercial grade without any post-accident environmental qualification. A decision was made not to specifically identify the potential long list of instrumentation available at BVPS-2 that meets tnis definition.

Indeed, if the list were generated, it would be much more inclusive than the variables identified in Reg. Guide 1.97, Revision 2.

4.

The installed equipment is a standard kfestinghouse Nuclear Instrumentation system, powered from a battery backed Class 1E Power Source. The equipment contains isolated monitoring channels which cover the range required to be monitored. The equipment is suitable for normal operation, and the qualified instr.ument rack portion is installed in the control room which is an accessible and controlled mild environment.

Currently, no sensors are commercially available with post-accident environmental qualification; therefore no implementation schedule can be provided at this time. Borating the primary system after an accident per the E0P's ensure that adequate shutdown margin is maintained.

6 l

5.

BVPS-2 is installing the Westinghouse differential pressure Reactor Vessel Level Instrumentation System (RVLIS).

This is an acceptable system for measuring coolant level in the reactor according to Generic Letter 82-28. BVPS-2 uses Core Exit Temperature and RCS Subcooling to support operation according to the Westinghouse Owners Group Emergency Response Guidelines. These guidelines require that the RVLIS meet Regulatory Guide 1.97 Category 2 criteria only. Operator verification of flows during safety injection operation and stringent termination criteria preclude the need for RVLIS under design basis accidents 6.

Pressurizer Heater Status - Regulatory Guide 1.97, Rev. 2 specified that heater current was the preferred parameter for determining heater status. For BVPS-2 heater breaker position, not current indication, was selected for determining pressurizer heater status due to hardware considerations. Breaker position provides adequate indication to the operator to ensure the pressurizer heaters are operable.

7.

The reconmended ranges for this instrumentation are: Wind speed 0 to 67 and -9 to 18'F for estimation of atmospheric stability. The instrumentation to be installed will cover the following ranges: Wind speed 0 to 50 mph and estimation of atmospheric stability T (150-35 ft)

-4.0 to +8.0*F; (500-35 ft) -6.0 to +12.0*F.

The instrumentation ior wind speed meets the guidance of Regulatory Guide 1.23. The vertical temperature ranges cover the range of lapse rates (change of temperature with height) guidance of Reg. Guide 1.23 required to estimate the atmospheric stability class.

8.

The licensing basis assumed in the BVPS-2 Regulatory Guide 1.97 Revision 2 Design Document was that a safe shutdown condition was a hot standby condition.

Parameters necessary to monitor the status of the plant while proceeding to a cold shutdown condition are not included in the Design Document. The accumulator pressure, accumulator isolation valvh status and accumulator nitrogen vent valve status were identified as Category 2 only if the plant has committed to safety grade cold shutdown.

9.

The Westinghouse Owner's Group Emergency Response Guidelines do not consider boric acid charging flow as a parameter to be used by operators I

during or following an accident.

Under these conditions borated water is pumped from the large volume RWST into the RCS.

BVPS-2 has designated RWST level, HHSI flow, LHSI flow, containment water level and emergency core cooling system (ECCS) valve status for monitoring the performance of the ECCS since the ECCS does not normally take suction from the boric ac. id tank.

If boration is used following an' accident, qualified charging flow indication and RCS sampling are used to demonstrate that the RCS is being adequately borated.

10.

The installed instrumentation is designed to Category 3 criteria and the measured temperature is from 0* to 200*F. The Westinghouse Owners Group Emergency Response Guidelines do not require operator action based on containment temperature indication, but rather use containment pressure indication, therefore containment temperature is considered a Category 3 parameter, and the existing range is adequate for normal operation.

11. The Westinghouse Owner's Group Emergency Response Guidelines do not require operator action based on containment sump water temperature indication. At saturated condition, sump water temperature can be inferred frca containment pressure.

Containment spray system valve status and containment spray flow indications are used to demonstrate that the Emergency Core Cooling System is operating properly when taking suction from the containment sump.
