DEFINITIONS CHANNEL FUNCTIONALTEST A CHANNEL FUNCTIONALTEST shall be the injection of a simulated signal into the channel as close to the primary sensor as practicable to verify OPERABILITY including alarm and/or trip functions.

CONTAINMENTVESSEL INTEGRfTY 1.7 CONTAINMENTVESSEL INTEGRITYshall exist when:

a.

All containment vessel penetrations required to be closed during accident conditions are either:

Capable of being closed by an OPERABLE containment automatic isolation valve system, or 2.

Closed by manual valves, blind flanges, or deactivated automatic valves secured in their closed positions, except for valves that are open on an intermittent basis under administrative control.

b.

Alf containment vessel equipment hatches are closed and sealed, c.

Each containment vessel air lock is in compliance with the requirements of Specification 3.6.1.3, d.

The containment leakage rates are within the limits of Specification 3.6.1.2, and e.

The sealing mechanism associated with each penetration (e.g., welds, bellows or 0-'rings) is OPERABLE.

I CONTROLLED LEAKAGE 1.8 CONTROLLED LEAKAGEshall be the seal water flow supplied from the reactor coolant pump seals.

CORE Al TERATION 1.9 CORE ALTERATIONshall be the movem'ent or manipulation of any fuel, sources, reactivity control components, or other components affecting reactivity within the reactor vessel with the vessel head removed and fuel in the vessel.

Exceptions to the above include shared (4 fingered) control element assemblies (CEAs) withdrawn into the upper guide structure (UGS) or evolutions performed with the UGS in place such as CEA latching/unlatching or verification of latching/

unlatching which do not constitute a CORE ALTERATION. Suspension of CORE ALTERATIONSshall not preclude completion of movement of a component to a safe position.

REACTIVITY CONTROL SYSTEMS BASES MOVABLE CONTROL ASSEMBLIES Continued Overpower margin is provided to protect the core in the event of a large misalignment

(> 15 inches) of a CEA.

However, this misalignment would cause distortion of the core power distribution.

This distribution may, in turn, have a significant effect on (1) the available SHUTD01A MARGIN, (2) the time-dependent long-term power distributions relative to those used in generating LCOs and LSSS setpoints, and (3) the ejected CEA worth used in the safety analysis.

Therefore, the ACTION statement ass'ociated with the large misalignment of a CEA requires a prompt realignment of the misaligned CEA.

The margin calculations which support the Technical Specifications are based on a steady-state radial peak of Fr 2.

When the actual F<, significant additional margin exists.

This additional margin can be credited to offset the increase in F with time that can occur following a CEA misalignment.

~ca.fe The ACTION statements applicable to misaligned or inoperable CEAs include requirements to align the OPERABLE CEAs in a given group with the inoperable CEA.

Conformance with these alignment requirements bring the core, within a short period of time, to a configuration consistent with that assumed in generating LCO,and LSSS setpoints.

However, extended operation with CEAs significantly inserted in the core may lead to perturbations in (1) local burnup, (2) peaking factors, and (3) available shutdown margin which are more adverse than the conditions assumed to exist in the safety analyses and LCO and LSSS setpoints determination.

Therefore, time limits have been imposed on operation with inoperable CEAs to preclude such adverse conditions from developing.

The requirement to reduce power in certain time limits depending upon. the previous F is to eliminate a potential nonconservatism for situations when a

CEA has been declared inoperable.

A worst-case analysis has shown that a

DNBR SAFDL violation may occur during the second hour after the CEA misalignment if this requirement is not met.

This potential DNBR SAFDL violation is eliminated by limiting the time operation is permitted at full power before power reductions are required.

These reductions will be necessary once the deviated CEA has been declared inoperable.

This time allowed for continued operation at a reduced power level can be permitted for the following reasons:

The limitation on linear heat rate ensures that in the event of a LOCA, the peak temperature of the fuel cladding willnot exceed 2200'F.

Either of the two core power distribution monitoring systems, the Excore Detector Monitoring System and the Incore Detector Monitoring System, provides adequate monitoring of the core power distribution and are capable of verifying that the linear heat rate does not exceed its limits.

The Excore Detector Monitoring System performs this function by continuously monitoring the AXIALSHAPE INDEXwith the'OPERABLE quadrant symmetric excore neutron fluxdetectors~i~L"

+Lg and verifying that. the AXIALSHAPE INDEXis maintained within the allowable limits of Figure 3.2-2.

In conjunction with the use of the excore monitoring system and in establishing the AXIALSHAPE INDEXlimits, the following assumptions are made:

(1) the CEA insertion limits of Specifications 3.1.3.5 and 3.1.3.6 are satisfied, (2) the AZIMUTHALPOWER TILTrestrictions of Specification 3.2.4 are satisfied, and (3) the TOTALPLANAR RADIALPEAKING FACTOR does not exceed the limits of Specification 3.2.2.

The Incore Detector Monitoring System continuously provides a direct measure of the peaking factors and the alarms which have been established for the individual incore detector segments

~

ensure that the peak linear heat rates willbe maintained within the allowable limits of

'igure 3.2-1. The setpoints for these alarms include allowances, set in the conservative directions, for (1) a measurement~lculational uncertainty factor, (2) an engineering uncertainty factor, (3) an allowance for axial fuel densification and thermal expansion, and (4):a THERMAL POWER measurement uncertainty factor.

kaattlLtwd8 The limitations on FT and T, are provided to ensure that the assumptions used in the analysis for establishing the Linear Heat Rate and Local Power Density - High LCOs and LSSS setpoints remain valid during operation at the various allowable CEA group insertion limits. The limitations on F~ and T, are provided to ensure that the assumptions used in the analysis establishing the DNB Margin LCO, the Thermal Margin/Low Pressure LSSS setpoints remain valid during operation at the various allowable CEA group insertion limits. If F~~, F~ or T, exceed their basic limitations, operation may continue under the additional restrictions imposed by the ACTION statements since these additional restrictions provide adequate provisions to assure that the ST.

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 uniform boron concentration is maintained for reactivity control in the water volume having direct access to the reactor vessel.

These limitations are consistent with the initial conditions assumed for the boron dilution incident in the safety analyses.

The value for K ff includes a

eff 2X delta k/k conservative allowance for uncerta nties.

Similarly, the bo~on concentration value ncludes a conservative uncertainty allowance of 50 ppm boron.

~pg~jfjgJ lA AIR COLA 3/4.9.2 INSTRUMENTATION The OPERABILITY of the startup neutron flux monitors ensures that redundant monitoring capability is available to detect changes in the

~

reactivity condition of the core.

3/4.9.3 DECAY TINE The minimum requirement for reactor subcriticality prior to movement of irradiated fuel assemblies in the reactor pressure vessel ensures that sufficient time has elapsed to allow the radioactive decay of the short lived fission products.

This decay time is consistent with the assumptions used in the safety analyses.

3/4.9. 4 CONTAINMENT BUILDING 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.

3/4. 9. 5 COMMUNICATIONS The requirement for communications capability ensures that refueling station personnel can be promptly informed of significant changes in the facility status or core reactivity condition during CORE ALTERATIONS.
