i (21) Spent Fuel Pool Ventilation System (Section 9.4.2, SER, $$ER #2) ,

If spent irradiated fuel is placed in the spent fuel pool prior to installation and operability of the safety related backup fuel pool cooling pump room coolers, the plant shall be placed in shutdown condition and remain shutdown with the RHR system dedicated to the fuel pool cooling mode.

(22) Remote Shutdown Panel (Section 9.5.4.1. SER, SSER #2)

Prior to startup following the first refueling outage, MP&L shall install electrical isolation switches between the control room and the Division 1 remote shutdown panel. l (23) Fire Protection Program (Section 9.5.9, SER)

MP&L shall maintain in effect and fully implement all provisions i' of the approved Fire Protection Plan. In addition, MP&L shall maintain the fire protection program to meet the intent of Appendix R to 10 CFR Part 50, except that an oil collection system for the reactor coolant pump is not required.

(24) Interplant Communication Systems (Section 9.6.1.2, SER, SSER #2, i 55ER #4, 55ER #5) l Tests of the communication systems used to mitigate the con-sequences of an event and attain a safe plant shutdown shall be I completed during preoperational and startup tests. An evaluation l of the test results shall be provided for NRC review within 90 l days after test completion. Any system modifications found l necessary as a result of NRC review shall be completed prior to startup following the first refueling autage.

- (25) Reliability of Diesel-Generators (Sections 8.3.1,9.6.3 through 9.6.7, SER, 55ER #2, 53ER #4, 55ER #6)

! (c) Incorporate a bypass or coincident logic in all Division 1 and 2 diesel generator protective trips, except for trips on diesel engine overspeed and generator differential cur-1 rent (Item No. 808, T.S. 4.8.1.1.2.d.16.d).

(38) Control Room Leak Rate (Section 6.2.6, SSER #6)

MP&L shall operate Grand Gulf Unit I with an allowable control l

i room leak rate not to exceed 590 cfm. Upon restart of construc-tion of Unit 2 control room, MP&L will be permitted to operate at a leak rate of 760 cfm as evaluated in SSER No. 6.

& zHscar The facility requires exemptions from certain requirements of Appendices l

D.

A and J to 10 CFR Part 50. These include: (a) exemption from General

Design Criterion 17 of Appendix A until startup following the first refueling outage, for (1) the emergency override of the test mode for the Division 3 diesel engine (2) the second level undervoltage protec-tion for the Division 3 diesel engine, and (3) the generator ground 4 i over current trip function for the Division 1 and 2 diesel generators (Section 8.3.1 of SSER #7) and (b) exemption from the requirements of Paragraph III.D.2(b)(ii) of Appendix J for the containment airlock testing following not required (Section normal 6.2.6 door of SSER opening #7 . These w) hen containment exemptions are integrity is authorized by law and will not endanger life or property or the connon l defense and security and are otherwise in dm ;:ublic interest. There-j fore, these exemptions are hereby granted pursuant to 10 CFR 50.12.
  • With the granting of these exemptions, the facility will operate, to l the extent authorized herein, in conformity with the application, as l

}

amended, the provisions of the Act and the rules and regulations of l the Commission. _,

E. MP&L shall maintain in effect and fully implament all the provisions l

of the Connission-approved physical security plan, guard training and qualification plan and safeguards contingency plan, including amend-

' ments made pursuant to the authority of 10 CFR Section 50.54(p). The l

approved plans, which are safeguards information protected under 10 CFR 73.21, are collectively entitled Grand Gulf Nuclear Station

" Physical Security Plan," Revision 1, 2 and 3; the Grand Gulf Nuclear Station " Security Training and Qualification Plan," and the Grand Gulf Nuclear Station " Safeguards Contingency Plan." The identification of vital areas and measures used to control access to these areas, as

' described in the physical security plan, may be subject to amendnents l

in the future based upon a confirmatory evaluation of the plant to determine those areas where acts'of sabotage might cause a release of radionuclides in sufficient quantities to result in dose rates equal l to or exceeding 10 CFR Part 100 guidelines.

a Insert to Facility Operating License NPF-29 Page 14 (40) With the plant in OPERATIONAL condition 4, SSW cooling tower basin A may be considered OPERABLE in accordance with Technical Specification 3.7.1.3 with less than a 30 day supply of water (without makeup) during the time that

' SSW basin B is drained to replace its associated service water pump provided:

a) SSW basin A water level is maintained greater than or equal to 87".

b) At least two sources of water (other than normal makeup with one source not dependent on offsite power) are available for makeup to SSW basin A.

This license condition may remain in effect until plant startup following the outage scheduled for fall 1985.
