Request for Exemption
Subject:
Compliance with Revised Section 10CFR50.48 and new Appendix R to 10CFR50.
Dear Sir:
Maine Yankee Atomic Power Company has reviewed the extensive criteria contained in revised Section 10CFR50.48 and the new Appendix R to 10CFR50, dealing with fire protection.
The following information is submitted in accordance with the schecule promulgated in Section 50.48(c) (1) through (5).
Section III.G, Fire Protection of Safe Shutdown Capability As discussed in reference (d) above, Maine Yankee has previously submitted a description of its safe shutdown capability, which we feel meets the requirement for an alternate shutdown capability to satisfy this section with the exception of the requireme,ts discusseo in reference (e).
Since that submittal, Maine Yankee has not received any official letter documenting agreement or disagreement with that submittal. Reference (e) requests an exemption to certain requirements of Appendix R which reflect upon a response to the criteria of this section. Lhtil we receive a response to these two letters, we cannot go further on our development of an alternate shutoown capability to meet the requirements of this section.
Section III.H, Fire Brigade The tRC staff held, as an open SER item, that the Shift Sucervisor should not be a member O! the leader of the fire origade. Maine Yankee has removed the Shift Suoervisor from the fire brigade, thus complying with Appendix R on this point, and closing the open item.

United States traclear Regulatory Commission Page 2 Attention:
Mr. Harold R. Denton, Director March 12, 1981 Section III.I, Fire Brigace Training The PRC staff held, as an open SER item, that the fire brigade leader training was not acceptable. We have changed the fire brigade leader training, and have a t2aining program that meets this section requirements.
Section III.J, Emergency Lighting Maine Yankee's existing Fire Protection SER commitments include the requirement to install additional emergency lighting in certain areas neeced for operation of safe shutdown equipment.
This additional lighting has been installed.
However, this previous commitment did not address the access and egress routes associated with these areas.
Additional ew rgency lighting units, with at least 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> battery power supplies, have 'een ordered.
It is expected that thess emergancy lights will be received and Ostalled prior to Novemoer 19, 1981 as required by 10CFR50.48(c)(2).
Section III.M, Fire Barrier Cable Penetration Seal Qualification As discussed in reference c) above, there is one particular set of penetrations which have not been sealed to meet tne requirements of this section.
The referenced letter noted that the seal would be inrtalled during the 1981 refueling interval, and requested an extension of implementation date.
The seal assembly has been developed and will be installed during toe 1981 refueling interval.
Section III.0, Oil Collection System for Reactor Coolant Punp As part of Maine Yankee's previous Fire Protection SER submittals, the details of a Reactor Coolant PJmp 011 Collection System were submitted to the staff. We recognize that this previous design does not meet all of the requirements of Appendix R and therefore, we hereby withdraw our previous submittal on this subject.
Maine Yankee hereby commits to redesigning its Reactor Coolant Pump 011 Collection System to address the applicable requirements of Appendix R to 10CFR50.
It is expected that the redesigned system will be installed during the 1982 refueling outage, which meets the schedular requirements of 10CFR50.48(c)(3).
de trust that the above provides you with the information needed.
If you have any questions or comments, please contact us.
Very truly yours, MAINE YANKEE ATOMIC P0wER CCNPANY NN
