l. Objective:

To demonstrate by type tests that the subject cable is capable of performing its intended function as installed at BSEP under loss of coolant accident conditions specified to BSEP. Testing to be per.

formed in accordance with applicable parts of IEEE Std 323-1974, IEEE Std 383- 1974, and Regulatory Guide 1.131. Appendix A establishes CPAL's position as to the appItcability of IEEE 383-1974 to this demonstration. .

2. Scope This program addresses operation during a design basis event I as required in Section 2.4 of IEEE Std 383-1974 Other aspects of cable qualt fication for Class 1-E Service are not an issue.

3. _ Cable Description Raychem-Flamtrol 1M unshielded jacketed cables having combined conductor insulation and jacket wall thiekness greater than .120 inches. UEAC Spectftcation 9527-01-113-40.

4. Cable Sample:

Test specimens to be fabricated from 7-conductor,12 AWG, unused cable available at BSEP, telected per Appendix 0. Primary insulation l

thickness is .045 inches and the jacket thickness is nominally .09 inches.

l 5. IMEP Servien conditions:

1 a) Nomal service voltage: 480 volts, maximum 528 volts.

b) Maximum service currentt 12 amperes.

c) Service Ltfet 40 years at 660C, 6.0 x 107 rads.

6. Il5EP Conditions To Re Simulated ,

a) Nomal service aging:

1) 0 years at 6600, 1.2 x 107 rads.

II) 40 years at 660C, 6.0 x 107 rads.

b) LOCA Enytronment:

'c) Thermal Aging (See Appendix C)

1) Condition At One specimen of each configuration aged at 123cc for 100 hours0.00116 days 0.0278 hours 1.653439e-4 weeks 3.805e-5 months simulates 8 years of service at 660C based on Arrhenius analysts of long tem thermal l ,

life data. .

11) Condition B: One specimen of each configuration a at 140aC for 100 hours0.00116 days 0.0278 hours 1.653439e-4 weeks 3.805e-5 months simulates 40 years life at 68 based on Arrhenius analysis of long tem themal life data.

9. LOCA $1mulation Test: .

l l a) Physical arrangements i 1) Mandrels with pre aged specimens mounted in pressure l vessel. Orientation depends on vessel design.

l -

it) Jacket ends of one specimen on each mandrel stripped to expose the primary insulation to the environment l*

Inside pressure vessel. Individual c aponents spliced to todtvidual penetrations leads inside pressure vossal.

til) Cable ends of remaining specimen on each mandrel sealed. ,

Exit pressure vessel through suitable penetrations. e (2)
