SUMMARY

Inspection on February 20-23, 1979

Areas Inspected

This routine unannounced inspection involved 26 inspector-hours onsite in

the area of review of startup testing activities.

Results

Of the areas inspected one apparent item of noncompliance was found in one

involving failure to effect proper corrective action in disseminating

area

the corrected value for Core Maximum Peaking Factor (366/79-09-01).

Exit Interview

The inspection scope and findings were summarized on February 23, 1979

with those persons indicated in Paragraph 1 above.

The inspector

discussed the apparent item of noncompliance related to the use of the

incorrect Core Maximum Peaking Factor (CMPF) in ascertaining acceptance

of results of certain startup tests. The licensee did not take excep-

tion to the findings and committed to conduct a re-evaluation of the

potential adverse impact on the acceptability of all startup test

results to date due to the usage of an incorrect CMPF.

Startup Test Results Evaluation

Six completed startup test procedures were reviewed by the inspector

to ascertain whether uniform criteria are being applied for evaluating

completed startup tests to assure their technical and administrative

adequacy. Each procedure was reviewed to verify:

Each procedure change was approved in accordance with the pertinent

a.

administrative procedures.

b.

That the test change had been completed if it entailed specific

action.

That the procedure change did not change the basic objectives of

c.

the test.

d.

That all test exceptions had been resolved and that the resolution

had been accepted by appropriate management.

That outstanding exceptions have been identified and if completed,

e.

proper approval signature obtained.

f.

If required, the retest requirements have been completed.

Licensee review and evaluation of the test results and acknowledge-

g.

ment that testing demonstrated system design requirements.

h.

That the licensee specifically compared test results with esta-

blished acceptance criteria.

That data sheets had been completed and that all data recorded

i.

where required are within acceptable tolerance.

j.

That those personnel charged with responsibility for review and

acceptance of test results have documented their review and

acceptance of test package.

The following documents were reviewed:

HNP-2-10422, Pressure Regulator Startup Testing - T.C. 1

HNP-2-10522, Pressure Regulator Startup Testing - T.C. 2

HNP-2-10622, Pressure Regulator Startup Testing - T.C. 3

HNP-2-10722, Pressure Regulator Startup Testing - T.C. 4

HNP-2-10822, Pressure Regulator Startup Testing - T.C. 5

HNP-2-10625, Main Steam Isolation Valves - T.C. 3

Three examples of the use and subsequent supervisory approval of an

incorrect value of Core Maximum Peaking Factor (CMPF) were identified

by the inspector in three different startup test procedures (STP).

All three cases involve Data Sheet 68 (from HNP-2-10001) which is useo

to calculate the neutron flux scram setting for comparison to the

observed neutron flux peak during the particular startup test. Specific

acceptance criteria for these STP's delineates the minimum acceptable

margin to the scram setpoint trip. A value of 2.48 instead of the

required 2.38 for CMPF was utilized in the calculation yielding a

higher than prescribed scram setpoint. This in turn had the potential

of compromising the acceptability of the test results relating to the

" flux-peak-to-scram-setpoint" acceptance criteria.

Such use of the incorrect CMPF was identified in the following STP's:

HNP-2-10422, Pressure Regulator (Attachment E/11)

HNP-2-10522, Pressure Regulator (Attachment E/13)

HNP-2-10625, MSIV (Attachment D/33)

The licensee committed to conduct a re-evaluation of all startup test

results to date whose acceptability could be adversely affected by the

above described findings.

The particular Jeviation from the original 2.48 value of CMPF to the

currently applicable value of 2.38 came as a result of the process

computer's calculational method of handling 150 inch 8x8R fuel assemblies

and was identified by the licensee via their internal Deviation Report

No.78-444.

Paragraph 16.1 of Section 16, " Corrective Action", of the Plant Hatch

Quality Assurance Manual obligates the licensee to " establish measures

to assure that conditions adverse to quality such as failures, malfunc-

tions, deficiencies, deviations, defective material and equipment, and

nonconformances are promptly identified and corrected." In the case of

significant conditions adverse to quality paragraph 16.1 further

requires that "the measures shall assure that the cause of the condition

is determined and corrective action taken to preclude repetition".

Based on the findings discussed above, it appears that adequate correc-

tive action was not taken to disseminate the new value of CMPF for

use, as appropriate, in plant procedures. This is an item of noncom-

pliance (366/79-09-01).
