l 7590-01 UNITED STATES OF AMERICA' NUCLEAR REGULATORY COMMISSION In the Matter of Docket Nos. 50-237 and 50-249 j
COMMONWEALTH EDIS0N COMPANY
]
Dresden Nuclear Power Station j
l Unit Nos. 2 and 3 j
l EXEMPTION J
I.
The Commonwealth Edison Company (CECO, the licensee) is the holder of 1
J 1
Provisional Operating License No. DPR-19, which authorizes operation of Dresden Nuclear Power Station Unit No. 2, and Facility Operating License No. DPR-25, which authorizes operation of Unit No. 3.
These licenses provide, among other.
things, that Dresden Nuclear' Power Station Unit Nos. 2 and 3 are subject to all 1
rules, regulations, and Orders of the Commission now or hereafter in effect.
The station comprises two boiling water reactors at the licensee's site located in Grundy County, Illinois.
)
I II.
On November 19, 1980, the Cormission published a revised Section 10 CFR 50.48 and a new Appendix R to 10 CFR Part 50 regarding fire protection features of nuclear power plants (45 FR 76602). The revis.ed i
Section 50.48 and Appendix R became effective on February 17, 1981.
Section 50.48(c) established the schedules for satisfying the provisions of Appendix R.
By letters dated March 1, 1985 and December 4, 1985, the licensee requested schedular exemptions for the completion of the installation of the following
?
fire protection items in both DreMen Unit Nos. 2 and I:
7590 i Fire Detection and Suppression:
Installation complete.except for documentation (August 1987)
Fire Barrier. Pipe and Conduct Penetration:
Seals complete -
l verification (August -1987)
Emergency Lighting: Complete except for hand held fluorescent lightfixture(August 1987)
Fire Wrap: Turbine Building Center Corridor (August 1987)
By letters dated March 12, April 18, May 30, and August. 18, 1986 and January 30 and April 14, 1987, the licensee provided additional information.
III.
Reasonable interim compensatory measures for fire protection and' post-fire safe shutdown capability must be provided in order to grant schedular exemptions from the implementation schedules defined in_10 CFR 50.48.
The licensee has implemented compensatory measures as detailed in the May 30, 1986 letter, which include roving fire watches until completion of the fire protection work identified in the exemption. The roving watch enters each area where compensatory measures are required every 20 minutes.
All procedures and training required for the fire watches for each area identified in the exemption have been completed. The fire watches will identify any indication of fire, smoke or burning odor and will immediately notify-the control room; in addition, the watches have been trained in the use of portable fire extinguishers.
If a fire should occur within any fire area monitored by tne roving fire watch patrols, there is reasonable assurance that the fire will be detected in its incipient stage before significant flame propagation or temperature rise occurs. Upon discovery of a fire, the control room will i
s'
L,..
7590-01 be immediately notified and a fire brigade response initiated. The fire patrols and watches will be capable of controlling or suppressing the fire to minimize damage pending arrival of the fire brigade.
The status for completion of Appendix R fire protection work for Dresden Unit Nos. 2 and 3 is as follows:
Fire Detection and Suppression:
Installation complete-except for documentation (August 1987)
Fire Barrier Pipe and Conduct Penetration:
Seals complete -
verification (August 1987)
Emergency Lighting: Complete except for hand held fluorescent light fixture (August 1987)
Fire Wrap: TurbineBuildingCenterCorridor(August 1987)
All other Appendix R related items are complete.
The above schedule represents a best effort under the circumstances by the utility.
Since 1980, the utility has spent over 25 million dollars in Appendix R modifications and has proceeded expeditiously to resolve technical 4'
open items and in completing modifications. The licensee is currently over 95 percent complete with Appendix R modifications.
The licensee has been delayed in completing all modifications because of the industry-wide concerns regarding the proper interpretation of Appendix R requirements.
NRC issued Generic Letter 83-33 to provide clarification. The licensee participated in a number of meetings and,;orkshops in 1983 held by the NRC concerning i
Appendix R and as a result initiated a major re-verification effort to 6
7590-01 assure compliance with the clarified intent of Appendix R.
This effort resulted in additional modifications.
It is this situation which in spite of best efforts, prevented the licensee from achieving compliance with the schedular requirements of 10 CFR 50.48. These delays were beyond the control of the licensee.
IV.
I Based on the considerations and current status of the fire protection related work discussed above, the staff has concluded that the licensee has provided a sound rationale for the need of schedular relief; a best effort i
is being expended to complete the Appendix R related work; the utility has l
proceeded expeditiously to meet the Commission's requirements; delays were caused by circumstances beyond the utilities control; and reasonable and acceptable interim measures for fire protection and' alternate shutdown capability to support the requested schedular exemption have been provided.
Therefore, based on our evaluation, the staff has concluded that the requested l
l schedular exemption from the requirements of 10 CFR 50.48, Section (c)(4) i should be granted.
1 Accordingly, the Commission has determined that, pursuant to 10 CFR 50.12, i
the schedular exemption requested by the licensee's letter of March 1,1985 j
and December 4,1985 as supplemented is authorized by law, will not present an undue risk to the public health and safety, and is consistent with the common defense and security.

l The Commission further determines that special circumstances, as
)
i provided in 10 CFR 50.12(a)(2)(v), are present justifying the exemption, namely that the exemption provides only temporary relief from the schedular
'1 4
requirements of 10 CFR 50.48(c) and the licensee has made good faith efforts to comply with the schedules in 10 CFR 50.48(c).
1 1
The Commission hereby grants the licensee exemption from the schedular-requirements of 10 CFR 50.48 Section (c)(4) for the following items and duration:
Fire Detection and Suppression:
Installation complete except for documentation (August 1987)
Fire Barrier Pipe and Conduct Penetration:
Seals complete -
verification (August 1987)
]
Emergency Lighting: Complete except for hand held fluorescent lig:.t fixture (August 1987)
Fire Wrap: Turbine Building Center Corridor (August-1987)
Pursuant to 10 CFR 51.32, the Commission has determined that the issuance of the exemption will have no significant impact on the env'ironment (51 FR 10954 dated March 31, 1986, renoticed 52 FR 31100 dated August 19, 1987).
For further details with respect to this action, see the requests for exemption dated March 1, 1985 as supplemented December 4, 1085, March 12, April 18, May 30 and August 18, 1986, and January 30 and April 14, 1987,
