I, William R. Kanda, Jr., being duly sworn, stato as fol-lows:

1. I am currently employod by The Cleveland Electric Illuminating Company ("CEI") as a Gonoral Supervising Engincor of the Porry Nuclear Power Plant ("Porry") Technical Depart-mont. My responsibilition include the overall supervision of tho engincora providing technical support to Plant operations.

I am also responsibio for the direction of the Instrument and Control Group at Porry. I provido the overall coordination for 0507230420000$f) pDH ADOCK 000 40 PDH Q

i

the investigation and resolution of plant events, such as the fire which occurred at Reactor Building No. 1 on May 5, 1985.

I am a graduate of the University of Detroit, from which I obtained a B.S. degree in Electrical Engineering in 1972. I also hold a M.S. degree in Managerial' Economics from Case West-ern Reserve University. I have been employed by CEI since 1973 and have been assigned to Perry since 1976. I have personal knowledge of the matters set forth herein and believe them to be true and correct.

2. On the morning of May 5, 1985, fast-speed, preoperational testing of the Unit 1, D-33 recirculation pumps was being conducted. Two-by-fours and plywood had been laid down to protect the reactor vessel mirror insulation during testing. This testing had been proceeding for a number of l days, causing the reactor vessel wall to roach temperatures ap-proaching 500 F. As a result of exposure to the high tempera-tures over a prolonged period of time, the two-by-fours and plywood spontaneously ignited near the top of the reactor vos-sol.

t

3. The firo was reported to the Perry Control Alarm Sta-cion at 2:05 a.m. The fire brigade was notified immediately and Reactor Duilding No. I was evacuated by security personnel.

4. Initially, dry chemicals were applied in an attempt i to extinguish the fire. Itowever, because of the intenso heat, the two-by-fours and plywood continued to ro-innito. At 2:30 l

.- -. . _ . . . . . - ~ - . . . - . . - - - - -

i a.m., it became apparent that the Perry Township. Fire Depart-

$ ment should be called because of the re-ignition problem. The i

j Fire Department arrived at the site in five minutes. By 5:00 a.m. the fire was extinguished by using a combination of water l -

and dry chemicals. There were no injuries and damage to equip-ment was minor.

f 5. The NRC resident inspector was notified at 7:00 a.m.

l Within twenty-four hours of the fire, Perry inspection teams  !

l I

were assembled by Nuclear Construction to investigate the im-  :

[ pact of the fire on a) piping supports; b) electrical equip-t

! ment and cables; c) instrumentation, impulse lines and sup-i ports; d) mechanical components; and e) the area between the L

bioshield and reactor pressure vessel. Twenty-five  !

j Nonconformance Reports (covering safety-related items), and five Deficiency Peports (covering non-safety-related items), [

were generated as a result of this investigation. Reports were i i

written for any item that was charred or might have been ad-versely affected by the heat generated during the fire. Neces- .

4 l l

sary corrective action is being taken by Nuclear Construction  !

j Engineering for each of the items identified by the inspection.  !

Those' items not already closed out will be closed out prior to  !

l I fuel load. i

! 6. All piping supports within the fire area were in- ,

spected by the piping contracts administrator, reactor building f i  !

l manager, senior civil / structural engineer, and operations and t

constructi,on quality control personnel. As a result of this inspection, seventeen snubbers (which act as " shock absorbers" f for the piping) have been replaced as a precautionary measure, j although no significant damage was apparent, due to the possi-T i bility of corrosion from the dry chemicals h plied during the fire. All of the snubbers will be replaced prior to fuel load.

7. Each electrical device and cable within the fire zone was inspected by a team of senior electrical engineers and  :

l quality control personnel for possible fire and/or heat damage.

Three Deficiency Reports and one Nonconformance Report were

! developed, covering each piece of equipment potentially affect-ed by the fire. Corrective action, as necessary, is being i

i taken in every case. All Reports have been dispositioned by j t

Nuclear Construction Engineering and will be closed out by fuel  ;

i load.

8. Inspection of instrumentation, impulse lines and sup-l ports in the fire zone by a team of Instrument and Control per- }

sonnel indicated that damage was minimal. Temperature elements l

i in the fire zone are being removed and recalibrated, with re- f placements being made, as necessary. Seven snubbers were re- f i

placed, as a precaution against corrosion, although none of l j

them showed signs of damage. Damage to a radiation monitor in l l

the fire zgne was assessed by a Deviation Report. The monitor has been recalibrated and the Report closed out.

9. A construction inspection team consisting of mechani-cal and welding engineers, quality control inspectors, and a coatings engineer inspected mechanical items in the fire zone.

Eleven Nonconformance Reports were generated as a result of their investigation. Necessary repair work for piping has been completed. Mirror insulation panels affected by the fire are being replaced. Remaining items have been dispositioned by Nu- l clear Construction Engineering and will be closed out prior to fuel load, i f

10. The space between the bioshield and reactor pressure  ;

vessel was inspected by a construction inspection team of me-chanical and welding engineers and a quality control inspector.

Dry chemical residue, charcoal particles, and some water were evident. No problems were anticipated with the small quan-  ;

tities of water and chemical residue found. The area will be l wiped down with de-mineralized water to remove the chemical j residue. ,

11. An investigation was conducted by a fire protection i specialist, compliance engineer, and two system enginoces to analyze the cause of the fire and to evaluate actions taken to l

[

extinguish it. As a result of their investigation of the incl- <

dont, a series of recommendations were made to improve Perry's response in such a situation. Recommendations included

I suggested. areas of improvement in radio cormunications, the placement and maintenance of fire-fighting equipment, as well as suggestions th modifications in the administration and coordination of fire-fighting personnel. Some of the recommen-1 i dations generated as a result of this investigation have al-i ready been implemented at Ferry. Othere are still being evalu-ated. All of the recommendations will be dispositioned prior

! to fuel load.
