All documents supplied to OCRE for inspection will be produced at Perry Nuclear Power Plant ("PNPP"). Arrangements to examine the documents can be made by contacting Mr. Allan Jones of The Cleveland Electric Illuminating Company at (216) 259-3737. Applicants will provide copies of any of the produced documents, or portions thereof, which OCRE requests, at Applicants' cost of duplication. Arrangements for obtaining copies can be made with Mr. Jones.

n-8-1. Exactly what type of polymer is Rockbestos Polymer LD? This substance is used as electrical insulation in cables manufactured by Rockbestos Co., which are used in PNPP (e.g.,

types EKC-81, 82, 83, 84, 85, 92, 93, 94, 95).

Response

Rockbestos Polymer LD is modified polyphenylene.

8-2. Section 2:07.10 of GAI Conformed Specification SP-567-4549-00 states that cable jackets shall be heavy duty chlorosulfonated polyethylene. Yet the cables (EFK-1 to EKF-35) which reference this specification have hypalon listed' as the cable jacket material. Is hypalon the same as chloro-sulfonated polyethylene? If not, explain. l

Response

Hypalon is Du Pont's registered trade name for chloro'sul-fonated polyethylene.

8-3. Some of the circuits listed in " Circuits by Equipment for PNPP, Unit 1" used cables identified as VEC-57, VFC-13, VFC-16, and VFC-17. These items appear not to have been referenced in the GAI Conformed Specifications provided.

Please produce specifications for these cables as well.

Response

VFC refers to vendor furnished cables which are supplied by equipment manufacturers in conjunction with their equipment.

VFC-16 and VEC-17 do not need to be qualified for radiation environments since they cre not used in safety-related cir-cuits. VFC-13 cable will not be used. Information on VFC-57 will be produced when it is available.

8-4. The GAI Confcrmed Specifications (e.g.,

SP-561-4549-00) state that the cables shall be suitable for operation with an integrated gamma radiation dose of 35 megarads in carbon, integrated over 40 years.

m. __ . ..

\

\

(a) What is meant by 35 megarads in' carbon?

(b) What dose rate, in rads / hour, is'used for the gamma radiation? For the neutron radiation?

(c) Is the maximum dose rate of "O.18 Megarads per hour, in carbon" listed for design basis event conditions the actual dose rate used to qualify the material? If not, explain.

Response

(a) One rad in carbon is equivalent to 100 ergs ,

absorbed per gram of carbon. Most radiation values given are -

in carbon. The term "in carbon" is usually omitted for convenience. .

(b) The dose rates for gamma radiation and neutron radiation are given in Amendment 10 to the FSAR, Tables 3.11-2 ,

through 3.11-8. These Tables will be made available for examination at PNPP.

j (c) No; several tests were used as the basis for i qualification of cable subject to GAI Conformed Specification i

SP-561-4549-000. The dose rates used in these tests varied between 0.32 and 0.63 megarads per hour. The testing was done in accordance with IEEE Standard 383-1974 which requires only that the dose rate shall not be greater than 1.0 megarad per hour. ,<

8.5. FSAR Section 3.11.2.1.3.5.(Amendment 9) states th't a a "well-supported maintenance /surveielance program in'conjunc- '

tion with a good preventive maintenanc'e program will assure that equipment that meets the specification is qualified for the designed life." Please describe,in, detail the maintenance /

l surveillance and preventive maintenanc) programs Applicants J

will use for electrical cable insulation. Specifically, how ,

will degradation be detected and corrected?.At what intervals will cables be inspected? Haw will ce61es in conduit or in other unaccessible locations be inspbeted?

8-6. FSAR Section 3.11 is unclear as to who is to perform the qualification of electrical equipment, vendor, Applicants, or some third party? Please clarify. '

s

Response

Applicants are responsible for ensuring that all safety-related equipment is qualified. The actual qualification may be done by equipment vendors, a third party or Applicants. To date, Applicants have not performed the qualification for 'ny a

electrical equipment.

8-7. Which of the four options listed in FSAR Section 3.11.2.2.1.7 is utilized for aging of electrical cable?

Response

An appropriate age conditioning process (Option Four) is used for electrical cable.

8-8. FSAR Section 3.11.2.2 states that safety-related electrical equipment in a harsh environment supplied by General Electric is qualified under NEDE-24326-P.

(a) Does GE supply any safety-related electrical cables used in a harsh environment? If so, list all such cables and provide their specifications.

(b) If so, please produce NEDE-24326-P, under an appropriate protective agreement.

Response

(a) No General Electric supplied safety-related cables will be used in a harsh environment.

t (b) Not applicable.
