3/4.9 REFUELING OPERATIONS BASES 3/4.9.1 BORON CONCENTRATION The limitations on reactivity conditions during REFUELING ensure that:

1) the reactor will. remain subcritical during CORE ALTERATIONS, and 2).a uni--

)

form boron concentration is maintained for reactivity control in the. water-volume having direct access to the reactor vessel. These limitations are con-sistent with the initial conditions assumed for the boron dilution incident in the accident analyses. The value of 0.95 or less for Km includes a 1% delta 3

e K/K conservative allowance for uncertainties. Similarly, the boron concentra-J tion value of 2350 ppe or. greater also includes a conservative uncertainty

- 1 allowance of 50 ppm boron.

3/4.9.2 INSTRUMENTATION 2

redundant monitoring capability is available to detect changes in the The OPERABILITY of the source range neutron flux monitors ensures that reactivity condition of the core.

3/4.9.3 DECAY TIME i

The minimum requirement for reactor subcriticality prior to movement of-irradiated fuel assemblies in the reactor pressure vessel ensures that suffi-cient time has elapsed to allow the radioactive decay of the short lived fis-i sion products. This decay time is consistent with the assumptions used in the accident analyses.

3/4.9.4 CONTAINMENT PENETRATIONS The requirements on containment penetration closure and OPERABILITY ensure that a release of radioactive material within containment will be restricted from leakage to the environment. The OPERABILITY and closure restrictions are sufficient to restrict radioactive material release from a fuel element rupture based upon the lack of containment pressurization potential while in the REFUELING MODE.

Operability r,f the containment airlock door requires that the door is capable of being closed; that the door is unblocked and no cables or hoses are being run through the airlock; and that a designated individual is continuously available to close the airlock door. This individual must be stationed at the outer airlock doc.r.

BASES 3/4.9.5 COMUNICATIONS r

The requirement for communications capability ensures that refueling i

station personnel.can be'promptly informed of significant changes in the-facility status or core reactivity condition during CORF ALTERATIONS.

3/4.9.6 REFUELING MACHig the The OPERABILITY requirements for the refueling machine ensure that:- (1) ding refueling machine will be used for movement of all fuel assemblies inclu those with a CEA inserted, (2) each machine has sufficient load capacity to lift a fuel assembly including those with a CEA, and.(3) the core internals and i

pressure vessel are protected from excessive lifting force in the event-they are inadvertently engaged during lifting operations.

Five finger CEAs are removed from the reactor vessel either along with the associated fuel bundle utilizing the refueling machine or can be removed without the associated fuel bundle utilizing the refueling machine auxiliary hoist. The four finger CEAs are inserted through the upper guide structure with two fingers in each of the two adjacent fuel bundles in the periphery of

-i the core. The four finger CEAs are either removed with the upper guide struc-ture and lift rig or can be removed with separate tooling prior to upper guide structure removal utilizing the auxiliary hoist of the polar crane or the refueling machine auxiliary hoist.

Coupling and uncoupling of the CEAs and the CEDM drive shaft extensions is I

accomplished using one of the gripper operating tools. The coupling and uncoupling is verified by weighing the drive shaft extensions.

.l 3 /4.9. 7 FUEL HANDLING MACHINE - SPENT FUEL STORAGE BUILDING A.

Refueling Operations The restriction on movement of loads in excess of the nominal weight cf a l

fuel assembly, CEA and associated handling tool over other fuel assemblies in the storage pool ensures that in the event this load is dropped (1) the activity release will be limited to that contained in six fuel assemblies, and (2) any possible distortion of fuel in the storage racks will not result in a critical array. This assumption-is based on the calculated results which demonstrate that, with credit taken for the fuel handling building filters, the offsite doses would be well within (less than 25%)

i the 10 CFR 100 limits.
