As discussed in Section 8, AOP-43 uses the Engineer on Shift to monito'r RPV water-level. Personnel in the Engineer on Shift position are undergoing training to become Shift -
Technical Advisors (STAS) to fulfill the Authority commitment to have the STA position be separate from the Shift Supervisor (SS) and the Assistant Shift Supervisor (ASS). As each Engineer on Shift becomes a qualified STA, the Engineer on Shift duties outlined in AOP-43 will be carried out by this STA.
If you have any questions, please contact Mr. J. A. Gray, Jr.

: a.      SAFE SHUTT,oWN SCENARIO AND TIMETABLE 0.1     Introduct19D The saf e shutdown scenario and timetable -information provided in this section is based on a worst-case fire af fecting the Control                    ,
Room      (Fire     Area VII/ Fire      Zone CR-1),        the   Relay   Room   (Fire Area VII/ Fire         Zone RR-1),        the    Cable      Spreading-   Room   (Fire Area VII/ Fire        Zone CS-1),        the    Battery      Room    Corridor   (Fire   ,
1 Area XVI/ Fire        Zone BR-5),       or- the      North     Cable   Tunnel   (Fire i
l Area ID/ Fire Zone CT-4 ) .          This worse-case fire scenario requires the use of an alternative shutdown method independent of th0 Control Room (CR) and as a result imposes the-most significant.
impact on manpower availability for achieving safe shutdown.                      The equipment and personnel used in this scenario are necessary to achieve hot shutdown in the initial stages of the event.                         This scenario assumes maximum fire damage and: relies on systems and equipment analyzed to be free from tire damage.                           Additional personnel will be recalled and will be used for operating safe shutdown equipment and assist in achieving cold shutdown conditions within       the'    72    hours     required       by-    10 CFR SG,    Appendix  _R, Sections III.G.1.b and III.L.S.                  The scenario presented in this section'is -integrated into James A. FitzF : trick-Nuclear Power Flant safe shutdown procedures.
0.2     Assumotiong The following assumptions have been made in performing this evaluation:
Page 8-1 i

(1)'  The plant is operating-at-100% power upon the occurrence of a fire.
(2)   The-reactor trips - either ' automatically or is -- manually tripped frcm the Control Room.
(3)   As a limiting condition, loss - of off-site power is assumed with respect to the availability of' components which could be relied on to achieve safe shutdown.
(4)   Single failures are not considered.
(5)   Spurious operations, with and without of f-site power, directly attributable to the fire are considered.
(6)   All equipment required for safe shutdown is assumed to be operational and in service prior to the fire.
(7)   All required mechanical components (valves , . etc . ) will remain mechanically operable.
(8)   Electrical. power is available to operate safe shutdown components      (pumps, MCCs,     etc.),   except   forL those components for which the electrical power supply _ has failed as a result of the fire.
O.3     Activities to be Accomolished Specific operator (s) activities must be performed to' achieve l
stable hot shutdown conditions.            Performance of these identified activities prior to exceeding           acceptable time limits will ensure' that the plant can be safely shutdown.
After    completion      of   the   required   initial    activities (approximately 30 minutes),          additional   personnel   will  become-i         available      to assist      in bringing the plant       to cold shutdown-l i
conditions within the 72 hours required by 10 CFR 50, Appendix R, Sections III.G.l.b and III.L.S.

Communications required to coordinate the activities necessary to achieve saf e shutdown outside of the Control Room are available.
In addition, 8-hour Appendix R lighting has been--provided to' allow operators to perform their activities.

8.4.11       Em2I.gancy Licht.ing As part of the Appendix R reanalysis effort, illumination level and duration testing was perf ormed on areas requiring access and egress to safe shutdown control panels and specific safe shutdown components where operation of the components is necessary.
As a result of this testing, modifications have been performed to achieve compliance with 10 CFR 50, Appendix                                                                              R,  Section III.J as described in Section 7 of this report.

8.5  Actions Reauired to Achieve shutdown for Fires Recuirina Control Room Evacuatio.n The actions required to achieve stable hot shutdown conditions will-be accomplished with five-operators and an Engineer on Shift.                                   ,
These actions will be accomplished within the first half-hour af ter evacuation of the Control Room.                         Safe Shutdown activities are identified and described in James                      A. FitzPatrick ileclear Power Plant Abnormal Operating Procedure AOP-43.

training to become Shift Technical Advisors (STAS) to fulfill the Authority commitment to have the STA position be separate from the Shift Supervisor (SS) and the Assistant Shif t Supervisor ( ASS) . -As each Engineer on Shif t becomes a qualified STA, the Engineer on Shift duties outlined in AOP-43 will be carried out by this STA.
Hot shutdown operator actions will proceed with the primary

I-          Appendix R event, required safe shutdown systems and components will be available such that reactor vessel depressurization;and RHR-LPCI injection can be performed (see Section 9.1.10 regarding.
NRC exemption).          The rnactor vessel will then be depressurized to Page 8-8 l

allow RHR-LPCI         injection.      Suppression    Pool              Cooling will   be established by filling the RCS and establishing alternate shutdown cooling.        Process mon'toring components have been ensured to be available such that operators can monitor reactor level, reactor pressure,        torus   level,    torus   temperature                and   other  cystem variables.

address safe shutdown for fire areas not requiring Contrcl Room evacuation.        This procedure, in conjunction with plant emergency operating       procedures will ensure safe shutdown during a fire in any plant fire area.        The detailed procedure is documented in plant Isbnormal Operating Procedure 28 (AOP-28).
