SUBJECT: PERRY UNIT 1, DESIGN INSPECTION (NRC INSPECTION REPORT NO.

50-440/97-201)

.

Dear Mr. Myers:

From February 17 through March 27,1997, the staff of the U.S. Nudear Regulatory Commission '

(NRC), Office of Nuclear Reactor Regulation (NRR) Special Inspection Branch, performed a

design inspection of the Unit I high pressure core spray (HPCS) system, the Unit i emergency

closed cooling (ECC) system, and their support systems. The purpose of the inspection was to

evaluate the capability of the selected systems to perform the safety functions required by their

design bases, the adherence of the systems to their design and licensing bases, and the consistency

of the as-built configuration and system operations with the updated safety analysis report

(USAR).

The findings of the inspection w'ere discussed during a public exit on April 22,1997, and are

presented in the enclosed report. The team identified significant findings, as discussed below and

in the report, which challenged the capability of the systems to perform their complete scope of

design basis accident mitigation actions. Where appropriate, your staff took immediate corrective

or compensatory actions to ensure system operability.

The team identified three examples where the facility was being operated or maintained difTerent!y

than described in the USAR or in vendor's design input information. Two of these examples were

not supported by a written safety or engineering evaluation. The first example involved

continuous operation of the suppression pool cleanup system and the second example related to

the improper setting of the governor speed droop for the division III emergency diesel generator.

These examples have a direct impact on the HPCS system performance. The third example,

determined by the NRC to be a potential unreviewed safety question (USQ), resulted from an

inadequate 10 CFR 50.59 safety evaluation for a change involving early use of operator action to

fill the ECC system surge tank in a post LOCA environment.

Mr. Lew W. Myers -2-

The team identified concerns with tornado missile protection of the HPCS and RCIC suction

piping from the condensate storage tank (CST) and protection of the CST level instrumentation

tubing. The existing plant configuration for this equipment did not conform to the licensing basis

described in the USAR. The current plant design and initial evaluation of the team's findings used

a probability approach, which difTered from the licensing basis described in the USAR and the

NRC's SER (NUREG-0887). This is considered to constitute a potential unreviewed safety

question.

For the two issues identified as potential unreviewed safety questions, you can restore the j

nonconforming systems to meet their licensing basis through the corrective action process.

However, ifyou wish to revise the licensing basis to reflect the existing plant configuration, you

should request an amendment to your license pursuant to 10 CFR Part 50.90 requirements. We

understand that you have determined that the nonconforming systems involved are operable.

.

The team found deficiencies in testing and surveillance activities at the plant. For example, the

test pressure used to monitor ECC and the nuclear closed cooling system boundary valve leakage

did not represent values that would be experienced under accident conditions. Also the corrective

action for previously identified problems associated with the diesel generator testable rupture disk

has not been effective in improving reliability of that equipment. l

The team noted design program weaknesses, including updating and control of calculations, and

nonconservative assumptions and inputs to calculations. In addition, the team identified

discrepancies and inconsistencies in the USAR, procedures, system description manuals (SDMs),

calculations, drawings, and other documents.

Your engineering stafrexhibited adequate knowledge of the systems evaluated and provided

excellent support to the inspection team. Although we considered the HPCS safety system self-

assessments performed by your staffin 1992, to be a positive initiative, the team identified some

significant issues that were not found in the self-assessment.

Please provide a schedule, within 60 days, detailing your plans to complete the corrective actions

for the open items listed in Appendix A to the enclosed report. This schedule will enable the NRC

staff to plan for the reinspection and closeout of these items.

As with all NRC inspections, we expect that your stafTwill evaluate the applicability of the results

and specific findings of this inspection to other systems and components throughout the plant.
