within 14 days.
If the instrument s are not restored to operable status within 14 days, pre (pa)re and submit a report to the Nuclear Regulatory Commission, pursuant to Section 5.9.3 of the Technical Specifications, within an additional l
30 days, outlining the cause of the malfunction and the plans for returning the Instrument (s) to operable status.

All but one (1) fire detection zone must be operable, with 50% or I
more of the detectors in a zone operable, in the containment building, except as provided by Section 2.19(3) of the Technical Specifications. With more than one inoperable fire zone:
Within one hour, establish a fire watch patrol to inspect the a.
zone with more than 50% ino)erable instrument (s) at least once per 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> operating s1ift, and b.

(ii) notify the Nuclear Regulatory Commission, pursuant to Section 5.9.2 of the Technical Specifications, outlining the cause of the malfunction, the actions taken, and the plans and schedule for restoring the system to operable status.
(iii) If (1) above cannot be fulfilled place reactor in
[
Hot Standby within the next 6. hours and in Cold
't Shutdown within the following thirty (30) hours.
(5)
The sprinkler system in'the Diesel Generator Rooms, the sprinklers above the steam driven auxiliary feedwater pump, the sprinkler / spray nozzle system in the compressor room, and the l
deluge system in the personnel corridor between fire areas 6 and-20 shall be operable except during system testing.
If inoperable:
Within one hour astablish a continuous fire watch with backup a.
fire extinguishing equipment for those areas in which 3
redundant systems or components could be damaged; for other-r areas, establish an hourly fire watch patrol.
2-91 Amendment No. JS,JJ.JE.JJJ
w 2.0 LIMITING CONDITIONS FOR OPERATION 2.19 Fire Protection System (Continued) b.
Restore the system to operable status within 14 days or prepare and submit a report to the Nuclear Regulatory Commission, pursuant to Section 5.9.3 of the Technical l
Specifications, within an additional 30 days, outlining the cause of the inoperability and the plans for restoring the system to operable status.
(6)
The fire hose stations designated in Table 2 8 shall be operable.
With a hose station inoperable, provide a hose of equivalent capacity which can service the unprotected areas from an operable hose station within one hour from the time that a hose station is determined to be inoperable if the inoperable fire hose station is the primary means of fire suppression; otherwise, route the additional hose within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />, (7)
All penetration fire barriers protecting safety related areas shall be functional (intact).
With a penetration fire barrier nonfunctional, within one hour, either establish a continuous fire watch on at least one side of the affected penetration, or verify the operability of fire detectors on at least one side of the penetration and establish an hourly fire watch patrol.
Restore the nonfunctional senetration to functional status within 7 days, or prepare and su)mit a report to the' Nuclear Regulatory Commission.
pursuant to Section 5.9.3 of the Technical Specifications, within an additional 30 days outlining the action taken, the cause, and the plans and schedule for restoring the penetration to functional i
status.
(8)
The control room, switchgear room and cable spreading room halon systems shall be operable with the storage tanks having at least 90% of full charge pressure and 95% of full charge weight or level. With a halon. system inoperable, establish a continuous fire i
watch with backup fire suppression equipment.
Restore the system to o)erable status within 14 days, or prepare and submit a report to tie Nuclear Regulatory Commission, pursuant to Section 5.9.3 of the Technical Specifications, within 30 additional 30 days, outlining the cause of the inoperability and the plans for restoring the system to operable status, i
M i
The fire arotection system provides a means for detecting, alarming, and i
extinguisling plant fires.
The system is divided into the fire detection subsystem and fire extinguishing subsystem, t
The fire detection subsystem is an instrumentation system which alarms control room operators of a fire, indicating fire location on a panel in the control room and providing a local indication from the detector in the affected zone.

DISCUSSIDN AND JUSTIFICATION OF AMENDMENT REQUEST i
i The proposed Technical Specification change deletes the requirement to provide a fuel performance report after each cycle of operation.
The Technical Specification document change is defined on page 5 15 of Section 5.9, and pages 2 69, 2 91 and 2 92 to change the references to Section 5.9.3.
The sroposed change for deleting Technical Specification requirement 5.9.3.h has )een previously approved in the Safety Evaluation Report for Amendment No.
77 to the facility operating license.
Thus, this change is considered administrative and does not affect the safe operation of the plant.
The requirement to provide the fuel performance report is duplicate to the Licensee Event Report System Rule (10CFR50.73) to report unique, widespread or unexpected fuel cladding failures in the reactor or spent fuel pool.
Page 2-89, 2-91 and 2-92 have been revised to reflect the change in references due to the deletion of item 5.9.3.h and the subsequent renumbering of the pages.
These changes are administrative since they ensure consistency between the references in Section 2.19 and 5.9.3 and do not affect the safe operation of the plant.
BASIS FOR NO SIGNIFICANT HAZARDS DETERMINATION This proposed amendment to the Technical Specification does not involve a significant hazards consideration because the operation of Fort Calhoun Station 1
in accordance with this amendment would not:
P (1)
Involve an increase in the probability or consequence of an accident previously evaluated.
This change implements a previously a) proved revision to the Technical Specifications.
Therefore, this c1ange does not increase the probability or consequences of a previously evaluated l
accident.
This change is considered administrative.
(2)
Create the possibility of a new or different kind of accident from any accident previously evaluated.
It has been determined that a new or different kind of accident is not created because no new or different-modes of operation are proposed for the plant.
The continued use of the i
l current Technical Specification administrative controls prevents the possibility of a new or different kind of accident.
(3)
Involve a significant reduction in a margin of safety.
Administrative specifications involving the deletion of the fuel performance report will not reduce the margin of safety.
Based on the above considerations, OPPD does not believe that this amendment involves a significant hazards consideration as defined by 10CFR50.92.-
