1- - c.
Miel pools.
d.

Inspections should include but not be limited to checks for:
fire,: flooding, system or component rupture, leakage, or inoperability, collapse or fracture of structures, loss of containment integrity, abnormal conditions of new or spent fuel, and any other hasardous or potentially hazardous situ-ation.
6.
When conditions permit, make an entry into the drywell to perform a general visual inspection of the reactor pressure 1
vessel and primary system components and piping to identify l
any obvious leakage of water or steam or other damage.
7.
Recover and replace the magnetic tapes and the etched event l
history cards from the triaxial tias history accelerograph and the triaxial peak accelerographs. Before removing the tapes from the accolographs, record a test / calibrate sequence on each tape. Mark each tape with.the recorder number and the date when tapes are removed.

If the Control and Computer Rooms Humidification System (M29) was shutdown due to the inability to aska a system inspection j
within the 20 minute time requirement, inspect the system as

Docket No. 50-440 Docket No. 50-441 The Cleveland Electric Illuminating Company ATTN: Mr. Murray R. Edelman Vice President Nuclear Group Post Office Box 5000 Cleveland, OH 44101 Gentlemen:
This letter confirms the telephone conversation between Dr. C. J. Paperiello of this office and yourself on January 31, 1986, related to the seismic event that occurred on January 31, 1986, in the vicinity of the Perry Nuclear Plant.
It is our understanding, with regard to this matter, that you will:
1.
Conduct a thorough review to determine if the earthquake was within the Desige Basis of tte plant (FSAR).
2.
Identify any damage as a result of this seismic event; determine if that level of damage was as expected.
3.
Determine that all equipment, including snubbers, that actuated during this event returned to normal operating ccnditions/ positions; identify any anomalies.
4.
Identify any acticns required to complete licensing of the plant related to this event.
5.
Maintain all affected equipment in the "as found" ccndition. Therefore, take no action such as removing, repairing or replacing equipment which would destroy or cause to be lost, any evidence which would be needed to investigate this event. Routine maintenance r.ay be performed provided that no information related to the event is altered or destroyed.
6.
Submit a formal report of your findings and conclusions to the NRC Region III Office within 30 days.

20555 paar Mr. theirunn:
As te are sure you are suam, an earthquake struck this corning $n the heart of i
sur congressional districts in northeast Ohio. Of immediate contam to,us is.the effect cf this earthquake on the structural integrity and safety of the Perry j
nuclear power plant in Perry. Ohio.
Please inform os hyltk00 a.m. Monday. February 3 ediether this agrthquake sawsed f
seismic forces at the Perry site in excess of those specified in the seimnic i
design for the Perry m actors. Please indicate the source of data which was i
used in obtaining the seismic force estimates, as well as a description of the i
process which was used in converting seismographic data into seismic force estimates.
I In addition, please, answer the following. questions:
l What will be the effect of this event upon the Perry fuel load date?
What was the nature, scope and extant of damage to safety related and non-safety related structures, systems and cesponents? What. if any leaks, occurred in safety and non-safety related systems?
i Did the devices which record seismic data perform in accordance with i
their precurweent specifications? Was the seismic data analysis l
performed in a tiasly and accurate manner?
At what time was the NRC operations omnter notified of this event?
At what time was the Commission notified? At what time were the relevant government entities in the Perry emergency planning area notified? Were these communications conducted in the timely manner l
specified in the perry Emergency Plant i
Wh1 e w to tre that the taformation we are requesting will necessarily he f a prell inary nature it is japortant that such prellsinary inferination
. I be available in order that we may adequately assess the suitability of the cumuission's regulations concerning agrthquake design for the Perry plant.
