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.

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