Dear Mr. Stratman:

SUBJECT: REACTIVE EMERGENCY OPERATING PROCEDURES FOLLOWUP INSPECTION

(NRC INSPECTION REPORT NO. 50-440/93018(DRS))

This refers to the inspection conducted by Messrs. R. A. Langstaff and

G. M. Nejfelt of this office on August 22 - 27, 1993. The inspection included

a review of activities authorized for your Perry Nuclear Power Plant. At the

conclusion of the inspection, the findings were discussed with those members

of your staff identified in the enclosed report.

Areas examined during the inspection are identified in the report. This

inspection focused on the response to two issues which pertain to emergency

operating procedures (EOPs). The specific issues reviewed were the ability of

plant procedures to meet the intent of the Boiling Water Reactor Owner's Group

(BWROG) emergency procedure guidelines (EPG) for secondary containment control

and the effects of containment venting upon surrounding buildings.

Originally, weaknesses in meeting the intent of the secondary containment

control guidelines were identified in our 1991 E0P inspection. Subsequently,

additional reviews completed by you in 1991 were used as a basis for informing

the NRC that the intent of the secondary containment control guidelines had

been met. However, the 1991 reviews were not thorough, and a comprehensive

review, performed in August 1993 at our request, identified that existing

plant procedures did not meet the intent of the secondary containment control

guidelines. Based on this discovery, additional E0P reviews were conducted.

We have evaluated your recent E0P reviews and corrective actions taken and

have determined both were comprehensive and conservative. We request that

within 30 days of receipt of this letter, you submit a summary of the report

developed from your E0P reviews to determine how existing plant procedures

meet the intent of the secondary containment control guidelines.

Also reviewed during this inspection were the effects of containment venting

upon surrounding buildings and potential overpressure concerns in those

buildings. We recognize that this issue was an outfall of the reviews i

performed of secondary containment. Nonetheless, we are concerned that

previous reviews failed to identify overpressure concerns in buildings

utilized to vent containment. Our concern stems primarily from the fact that )

containment venting procedures were reviewed in response to an escalated

enforcement action issued in 1991. The failure to perform an adequate

technical verification of the E0P venting procedures is considered a violation

of NRC requirements. However, this violation is within the scope of a

recently issued corrective action violation for which licensee actions are

still in the process of being implemented. Consequently, no Notice of

Violation will be issued for this example. We are encouraged that the

immediate corrective actions for this issue were both comprehensive and

timely. Based on information provided during the inspection, we understand

that additional analyses are being performed to assess the effects of

containment venting upon the surrounding buildings. We request that a summary.

of the results of your engineering analyses and planned corrective actions be

provided as soon as possible after completion.

In accordance with 10 CFR 2.790 of the Commission's regulations, a copy of

this letter and the enclosed inspection report will be placed in the NRC

Public Document Room. i

We will gladly discuss any questions you have concerning this inspection.

Sincerely,
