BIG ROCK POINT PLANT - REQUEST FOR EXEMPTION FROM 10 CFR 50 APPENDIX J, SENSING LINES FOR CONTAINMENT PRESSURE Consumers Power Company letter dated February 13, 1976 reported the results of a review of all piping penetrations required under the Type C testing require-ments of 10 CFR 50 Appendix J and requested specific exemptions. The letter identified five sensing lines for containment pressure instrumentation and concluded Type C penetration testing was not necessary.
By telephone conver-sation of August 3, 1982, you informed us that our February 13, 1976 letter was not considered an exemption request for the five containment pressure sensing lines. Our letter of Acgust 19, 1982 therefore specifically requested relief from the 10 CFR 50, Appendix J Type C testing requirements for the containment pressure instrument lines.
On September 28, 1982, the concurrence that Type C testing is not arplicable for the five instrument lines was provided via telephone conversati >n.
How-ever, we were also informed that an exemption for Type B testing is required.
Therefore, it is the intent of this letter to specifically request relief from the 10 CFR 50, Appendix J Type B testing requirements for the containment pressure instrument lines at the following penetrations:
H-89, H-90, H-96, H-98, H-99 This relief request is supported by Franklin Research Center via their Technical Evaluation Report (TER) dated April 30, 1982 and titled Containment Leakage Rate Testing - (A-04).
The report recommcnds that exemptions for the instrument pressure lines be granted. It notes that the lines are tested as

In addition, it should be noted that no significant degradation of the penetration seals has been observed.
