1.0 INTRODUCTION

The Salem No. 2 full power operating license contains Condition 2.c(5) which requires PSE&G to submit a response to a series of NRC questions on setpoint methodology. This document contains the Westinghouse and Public Service j

Electric and Gas response to those questions.

ll The infonnation desired pertains to the various instrument channel components' l

analysis assumptions i.e., a channel breakdown and values, for the Reactor Protection System (RPS) and the Engineered Safety Features Actuation System (ESFAS). Some of the infonnation requested is already available in public The rest of the documents, e.g., Chapter 14 of the Safety Analysis Report.

l infonnation has not been released and is drawn from equipment specifications or analysis assumptions. This infonnation is considered proprietary by West-inghouse and is noted as such.

The basic underlying assumption used is that several of the error components i

and their parameter assumptions act independently, e.g..

to be intsactive, the technique uses arithmetic strmnation, e.g.,

I 2.0 COM INATION OF ERROR COMPONENTS I

l 2.1 Methodolony The methodology used to combine the error components for a channel is bast-cally the appropriate statistical combination of those groups of connponents which are statistir. ally independent, i.e., not interactive. Those errors which tre not indept.n#ent are Sred arithn.etica11y into groups. The groups

'l themselves are independent effects which can then be systematically c.ombined.

l The methodology used for this combination is not new. Basically it is the ts.c.e

{

which hu been utilized in other Westinghouse reports. This technique, or other statistical approaches of a similar nature, have been used in WCAP-9180fI)andWCAP-8567(2)

It I

should be noted that WCAP-8567 has been approved by the NRC Staff thus noting the acceptability of statistical techniques for the application requested.

It should also be recognized that the approach used in this document was sub-mitted on the D. C. Cook Unit No. 2 Docket (50-316) and approved by the NRC Staff in a letter dated February 12, 1981. Thus it can be seen that the use I

of statistical approaches in analysis techniques is becoming more and more l

widespread.

l The relationship between the error components and the total statistical l

error allowance for a channel is,

3.0 RESPONSE TO NRC QUESTIONS E

s 3.1 Approach l

As"noted in Section Une, Westingho'use utilizes a statistical saunation of

.the various compoaants of the channel breakdown. This approach is valid

.where no dependencysis present. An arithmetic sumation is required where an'ir.teraction between two parameters exists. Section Two provides a more detailed explanation of this approach. The equation used to determine the h

margin, and 7thus the acdeptability of the parameter values used, is:

Rack Allowable Deviation The tolerances are as follows:

This accuracy may be ignored. All rack modules individually must

have a reference accuracy within percent.

b.

Rack Environmental Effects Includes effects of temperature, humidity, voltage, and frequency changes of which temperature is the most significant. An accuracy tabc of percent is used which considers a nominal ambient l

temperature of 70 F with extremes to 40'F and 120 F for short 0

Comparator Setting Accuracy Asstaning an exact electronic input. (Note that the channel accuracy takes care of deviations from this ideal), the tolerence on the pre-cision with which a comparator trip value can be set, within such practical constraints as time and effort expended in making the l

setting.

14 3.3 NRC Questions The inforination requested by the NRC for each channel is:

I What is the technical specification trip setpoint value?

l 1.

2.

What is the technical specification allowable value?

3.

What instrument drift is assumed to occur during the interval between l

technical specification surveillance tests?

4.

What are the components of the cumulative instraent bias (e.g., instra-ment calibration error, instrument drift, instrisnent error, etc.)?

5.

What is the margin between the sum of the channel instrumentation error allowances and the total instrumentation error allowance assumed in the accident analysis?

l The Westinghouse and PSE&G response to these questions is:

The response to Question I will be found as Column 14 of Table 3-4 in a.

this section.

Column 13 of Table 3-4 provides the information requested in Question 2.

b.

I The instrument drift assumed is the difference between the trip setpoint c.

and the allowable value in the technical specifications, this can be found as Column 11 of Table 3-4.

The bulk of Table 3-4 provides the breakdown values required by Question 4.

d.

The margin requested by Question 5 is noted in Column 17 of Table 3-4.

i e.

It should be remembered that responses are provided only for those channels for which credit is taken in the accident analysis. Again this is due to the fact that Question 5 cannot be answered if the channel is not a primary trip.
