Enclosure SUPPLEMENT NO.
3 TO THE FEBRUARY 14 1979 FIRE PROTECTION SAFETY EVALUATION REPORT BY THE OFFICE OF NUCLEAR REACTOR REGULATION U. S.
NUCLEAR REGULATORY COMMISSION PROVISIONAL OPERATING LICENSE NO.
DPR-18 ROCHESTER GAS AND ELECTRI,C CORPORATION R.
E.
GINNA NUCLEAR POWER PLANT DOCKET NO. 50-244 DATE.
June 22, 1981 Si07i50433 Si0622 PDR ADOCK 05000244 F
INTRODUCTION On February 14, 1979, the Commission issued Amendment No.
24 to Provisional Operating License No.
DPR-18 for the R.
E.
Ginna Nuclear Power Plant.
This
~ - amendment added a license condition regarding completion of facility modifi-cations to improve the fire protection program.
These modifications were identified in Paragraphs 3.1.1 through 3.1.49 of the NRC's Fire Protection Safety Evaluation (FPSE) for the Ginna Plant, also dated February 14, 1979.
By letter dated June 3, 1981, Rochester Gas and Electric Corporation (RGSE)
(the licensee) requested a revision to the requirements of Item 3;1.30, Fire Door Supervision, as stated in the FPSE of February 14, 1979.
DISCUSSION, EYALUATION AND CONCLUSION The FPSE requirement for Item 3.1.30 stated that all fire doors would be
"...electrically supervised with time-delayed alarm and annunciation in a constantly occupied area, or they will be locked closed."
RGLE has requested a revision to this requirement in the case of five out of the twenty-two fire doors to be installed at Ginna.
These five doors are located in the fire barriers between the turbine building and the:
A and B battery rooms; air handling room; and A and B diesel rooms.
These doors are collocated with security/pressure doors and none of the doors is installed in an area protected by an automatic total flooding gas suppression.
system.
The security force at Ginna is responsible for checking vital areas and
'ital doors every eight hours.
During these tours they would also be-respons'ible for checking the position of the above-listed fire doors that are collocated with security/pressure doors.
On february 17, 1981, 10 CFR 50.48 and Appendix R to 10 CFR 50 became effective. 'hese contain the requirements for fire protection features of nuclear power plants and wer e originally published on November 19, 1980 (45 FR 76602).
Section III.N of Appendix"R deals specifically with fire doors and provides alternative measures for protecting the opening in case of a fire.
One of the alternatives, III.N.4, states:
"Fire doors shall be kept closed and inspected daily to verify that they are in the closed position."
The proposed revision of Item 3.1.30 for Ginna is therefore acceptable because it meets present requirements.
RGSE has also requested that Item 3.1.30 be further changed to specifically addr ess the supervision requirements for the relay'oom, which's the only space protected by an automatic total flooding gas suppression system.
Because identical requirements are specified in Section III.N of 10 CFR 50 Appendix R, we conclude the revision is acceptable.
0 C /
-Accordingly, Item 3.1.30 of the FPSE is revised as follows:
3.1.30 Fire Door Su ervision All fire doors will be electrically supervised with time delayed alarm and annunciation in a constantly occupied area, or kept closed and inspected daily to, verify that they are in the closed position.
Because the relay room is protected by an automatic total flooding gas suppression system, relay room fire doors shall be electrically supervised with time del.ayed alarm and annunciation in a constantly occupied area.
