Introduction The purpose of this inspection was to compare the installed plant instrumentation with the commitments contained in correspondence related to Post-Accident Instrumentation and as described in the Safety Evaluation Report (SER).
This inspection also assessed if the instrumentation meets the criteria specified'n Regulatory Guide 1.97.
Some of the references used to assess the licensee conformance to Regulatory Guide 1.97 were:
Regulatory Guide 1.97, Revision 2, "Instrumentation for Light Water-Cooled Nuclear Power Plants to Assess Project and Environs Conditions During and Following an Accident" Safety Evaluation Report, in Memo Joyce to Knighton, 8/18/87, with Technical Evaluation Report prepared for the NRC by EGSG Idaho Inc.,

(WNP-2) Final Safety Analysis Report (FSAR), Chapter 7.
Generic Letter 82-33 issued supplement 1 to NUREG-0737, which specified those requirements regarding emergency response capability that had been approved by the NRC.
This supplement also discussed in part the application of Regulatory Guide (RG) 1.97 to the emergency response facilities, including the Control Room (CR), Technical Support Center (TSC) and Emergency Operations Facility (EOF) at power plants.
The licensee's response to RG 1.97 was provided in letters dated April 15, 1983, October 8, 1985, October 14', 1985, and January 23, 1986.
In general, the inspection verified that the licensee had documentation available onsite that showed the redundancy, physical and electrical separation, power sources and interfaces for the instrumentation.
The master equipment list (HEL) showed that for the instruments selected, they had been evaluated and tested to the appropriate environmental, quality assurance (gA) and seismic qualification requirements.
The environmental qualification (Eg) tests are tabulated below for the instruments by showing the Eg listing or the environment that the component is located in.
A mild environment would not need any special qualification.
The seismic listing shown below notes the class to which that equipment is qualified, Class I being the highest.
The gA procurement for several of these instruments was also reviewed and,no problems were identified with the procurement or the procurement gA program.
The inspectors noted that tracing of the power supply from the instrument to the instrument bus on the electrical drawings was cumbersome, but available.
The inspectors did not trace any wiring in the field.
The licensee has an ongoing effort to reduce the complexity of the drawings.
The inspectors also noted some discrepancies between the FSAR and the Regulatory Guide.
This was also identified by the licensee and will be changed in the next FSAR amendment (Number 39).
The inspector observed the accessible instrumentation transmitters for the class 1 variables selected.
The connections, piping, and general condition of the transmitters was assessed.
There were no problems identified.
Regulatory Guide 1.97 divides Post-Accident instrumentation into 3 categories and 5 types.
The three categories are I, 2 and 3.
Category
instruments have the most stringent requirements and category 3 the least stringent.
The five types of instrumentation identified in the Regulatory Guide are types A, B, C, D, and E.
Type A are plant specific and are identified by the licensee; type B variables provide information to indicate that plant safety functions are being accomplished; type C
'ariables provide information on the breach of barriers for fission product release; type D variables indicate the operation of individual safety systems; and type E variables are those that indicate and determine the magnitude of the release of radioactive materials.
Each variable type can have instrumentation variables in any category, except for type A, which can only be category The specific information on the instrumdntation inspected is shown in paragraph 3.
Except as noted in the inspection findings, the requirements for Class 1 and Class 2 instruments were met.

Ins ection Details The inspectors held discussions with various members of the licensee's staff, examined drawings and other documentation, and walked through the control room to assess the implementation of the requirements delineated in Regulatory Guide 1.97, Revision 2, at WNP-2.
Power is from the 120 VAC vital buses unless otherwise noted.
The following instrumentation was examined.
3.1 Neutron Flux The licensee determined that this is a Type A variable.'
Type A variable provides primary information required to permit the control room operator to take specific manual actions for which no automatic control is provided.
These actions are required for the safety systems to accomplish their safety functions for design basis events.
Neutron flux is also a
Type B variable.
Category 1 instrumentation is required for this variable as Type A and as Type B.
The neutron flux recorders indicate over the range of zero to 100 percent of full power, and the signal processor has a
log scale of 10E-8 percent to 200 percent of full power and a linear scale of 0 percent to 200 percent of full power.
The instrumentation automatically switches from the pulse mode to the cur rent mode for continuous indication.
Information on the neutron flux instrumentation was as follows:

Progress on the environmental qualification of this system is presently being reported to the NRC quarterly.
Ins ection Findin s The neutron flux level is available to the operator on continuous linear scale recorders and continuous log scale and linear scale indicators.
With the exception of environmental qualification,'he neutron flux instrumentation was found to meet the Category 1 recommendations specified in Regulatory Guide 1.97, Revision 2.
Environmental qualification of this
system is ongoing, with quarterly reports required to be provided to the NRC to detail progress in the qualification efforts.
Because of the lack of environmental qualification, this instrumentation is not yet a part of the ongoing surveillance program.
Power ascension testing has established preliminary calibration data for the chambers.
3.2 Coolant Level in Reactor The licensee has determined this variable to be Type A.
This Category
instrumentation is used to assure core cooling by monitoring the amount of core coolant and the trend (increase or decrease)
in the coolant level.
Instruments with overlapping ranges are used to cover the range recommended by the regulatory guide.
Also, as accepted by the WNP-2 SER, the instrumentation that measures above the wide range instruments is not Category l.
Information on the coolant level in the reactor instrumentation was as follows.

Meter was mislabeled for bus B.
2.
Meters were not labeled for charge/discharg Ins ection Findin s As footnoted in the above table, some meters were anomalistic.
These meters were mentioned to the licensee.
Also, most of the meters were labeled by bus only, and not with the instrument tag number.
These anomalities were brought to the attention of the licensee.
Verbal agreement was given that these anomalities should be corrected.
Other than this, the instrumentation was found to meet the Category
recommendations of Regulatory Guide 1.97, Revision 2.
All of the instrumentation that displays the status of standby power was found in calibration within normal time limits of the specified interval.
The inspectors found this instrumentation acceptable for meeting the Regulatory Guide 1.97 recommendations with the exception of labeling of the indicators.
The labeling is an item that will be followed up in a future inspection report (50-397/88-19-01).
4.
Surveillance Testin and Calibration For the instruments selected, the inspectors asked for the frequency of calibration, the date last calibrated, the next calibration due date, and the procedure which calibrated that instrument.
All of the RG-1.97 instrumentation inspected was found to be in calibration at the time of the inspection.

'n May 20, 1987, an exit meeting was held with the licensee representatives identified in paragraph 1.
The inspector summarized the inspection scope and findings as described in this report.
