J 3.8 FUIL LOADING A D REFUELING Aeolica5111tv Applies to fuel loading and refueling opera:1ces.
Obiective To <squre that fuel leading and refueling operations are perfor=ed in a responsible manner.
Seecifica:icn 3.3.1 Radia:1cn levcis 1: the reactor building refueling area shall be
=eni:cred by RIA-2
- and RIA-3.
Radia:1cn levels 1: the spent fuel storage area shall be =cci:cred by RIA-6 If any of these instr.=:e :s becc=es inoperable, portable survey instru=es:atic=,
having the appropriate ranges and sensi:ivi:7 to fully pro:act individuals involved in refueling operatica, shall be used until the per=anent instrumen:ation is returned to service.
f 1
3.8.2 Core suberi:1 cal neutron flux shall be continuously =oni:ored by at leas: vo neutron fluz =cnitors, each with continucus indica:ica available, whenever core gec=e:ry is bel =g changed.
When core gecmetry is not being changed, a: least one neutron flux =cni:cr shall be in service.
3.3.3 A: least cue low pressure injec:1cn pu=p and cooler shall be operable.
3.8.4 During reac:0: vessel head ra:cval and while leading and unicading fuel-frem the reacter, the boren concentratica shall be =aintained a:
not less than tha: required :s shutdevn :he core :o a kaff g0.99 if all ccatrol rods were re=cved.
3.3.3 Direc
cc==unica:icas between :he ccatrol rces and the refueling personnel in :he reac:cr building shall exis: whe aver changes in ccre gec=e ry are taking place.
3.3.6 Ouri:g the handling of irradia:ed fuel in :he reactor building a:
leas: cae deer c
- he personnel and e=erge cy ha:ches shall be closed.
The equipnent ha:ch cover shall be in place vi:h a =1sd "' of four bol:s securing the cover :o the sealing surfaces.
3.3.7 Soth isola:icn valves in lines containing au:c=atic ec=:ai=se==
isola: ion valves shall be operable, or a: least cae shall be closed.
3.3.3 When evo irradia:ed fuel asse blies are being handled sinul:anecusly within the fuel transfer canal, a mini =um of 10 feet separa:icn shall be satstained be:veen :he asse=blies at all ti=es.
Irradiated fuel assemblies =ay be handled with :he Auxiliary Ecis:
provided no other irradia:ed fuel asse=bly is.being handled in the fuel transfer canal.

A 4.4.2 Structural Integrity Aeolicability Applies to the structural integri r of the Reactor Building.
Obiective To define the inservice surveillanc e progra= for the Reactor Building.
Soecification 4.4.2.1 Tendon Surveillance For the initial surveillance progra=, covering the first five years of operation, nine tendens shall be selec:ed for pe=kdie inspection for sympte=s of =aterial deterioration or force redue:1on.
The surveillance tendons shall censist of three horizontal tendens, one in each of three 120* sectors of the contain=ent; three vertical tendons located at approximately 120* apart; and three dc=e tendons located approxi=ately 120* apart.
The following nine tendons have been selec:ed as the surveillance tendons:
Dc=e 1D28 Z328 (Uni: 1 and 3 only) 3D28 Hori: ental 13E9 51H9 53H10 Vertical 23V14 4fV16 1
61V16 4.4.2.1.1 Lif:-Off Lif:-off readings shall be :aken for all nine surveillance tendens.
4.4.2.1.2
'41re Inspec:1ca and Tes5ing One surveillance tendon of each directional group shall be relaxed and cne wire f c= each relaxed tenden shall be re=oved as a sa=ple and visually in-spected for corresion or pit:ing.
Tensile :ests shall also be perf ormed en a
=ini=u= of three speci= ens taken frc= the ends and =iddle of each of the three wires.
The speci= ens shall be the =axi=u= length acceptable for :he test appara:us to be used and shall include areas representative of sig-nificant corresien or pitting.
Af:er the wire re=cval, the tendens shall be retensiened to the. stress level
=easured at the lift-off reading and then checked by,a final lift-off reading.
Should :he inspection of one of :he wires reveal any significant corresion (pi::ing or loss of area), further inspection of the other two sets in : hat
' directional L cap will be =ade to deter =ine the extent of the corrosien and i

4.6 EMERGENCY P0bc2 PERIODIC TESTING
~
1
'Acolicability Applies to the periodic testing and surveillance of the emergency power sources.
Obiective To verify tha: the emergency power sources and equipment will respond prc=pely and properly when required.
Soecification 4.6.1 Monthly, a tes: of the Keewee Hydro unies shall be perforced to verify proper operation of these e=ergency power sources and associated equipment.
This test shall assure that:
Each hydro unit can be auteca:ically started from the Uni: 1 a.
and 2 control roo=.
b.
Each hydro unit can be synchronized through the 230 kV over-head circui: to the startup transformers.
'Each hydro unit can energi e the 13.8 kV underground feeder.
c.
4.6.2 Annually, the Keevee Hydro units will be started using the c=ergency star: circuits in each centrol rec = to verify that each hydro unit and associated equip =ent is available :o carry load within 25 I
seconds of a simulated require =ent for engineered safety features.
4.6.3 During each refueling cu: age, for the affected unit, a si=ula:ed emergency transfer frc= the 4160 vol: =ain feeder. buses :: :he startup transformer (i.e., CT1, CT2 or CT3) and to the 4160 vel:
standby. buses shall be made to verify proper operation.
4.6.4 Cuarterly, the External Grid Trouble Protection Syste= logic shall be tested to demonstrate 1:s ability :o provide.an isolated pcwer path berween Kecuee and Ocenee.
i.6.5 Annua lly, it shall be de=enstra:ed : hat a Lee 5:stion ce= bus cien '
- urbine can be started and connec:ec to :he 100 kV line.
It shall be demons trated tha
- he 100 kV line can be separated frc= the
, rest of the syste= and supply power to the 4160 vol: main feeder buses.
4.6.6 Batteries in the 125 VDC syste=s shall be tested Jul follows:
The voltage and temperature of a pilot cell in each bank shall a.
be =easured and recorded five times per week for the Instrument and Control, Keewee Hydro, and Swi: chine Sta:ica batteries.
b.
The specific gravity and vol: age at eacn cell shall be =easured and recorded monthly for the. Ins trumen: and Control, Keowee Hydic, and Switching Station batteries.
