i WATERFORD - UNIT 3 3/4 1-20
REACTIVITY CONTROL SYSTEMS BASES BORATION SYSTEMS (Continued) i The contained water volume limits include allowance for water not available because of discharge line location, instrument tolerances, and other physical
}
characteristics.
The OPERABILITY of one boron injection system during REFUELING ensures that this system is available for reactivity control while in MODE 6.
l The lower limit on the contained water volume, the specified boron concen-tration, and the physical size (approximately 600,000 gallons) of the RWSP also ensure a pH value of between 7.0 and 11.0 for the solution recirculated within containment after a LOCA. This pH band minimizes the evolution of iodine and minimizes the effect of chloride and caustic stress corrosion on mechanical systems and components.
i The maximum limit on the RWSP temperature ensures that the assumptions used in the containment pressure analysis under design base accicent condi-tions remain valid and avoids the possibility of containment overpressure.
The minimum limit on the RWSP temperature is required to prevent freezing and/
or boron precipitation in the RWSP.
3/4.1.2.9 BORON DILUTION This specification is provided to prevent a boron dilution event, and to prevent a loss of SHUTDOWN MARGIN should an inadvertent boron dilution event occur.
Due to bcron concentration requirements for the RWSP and boric acid makeup tanks, the only possible boron dilution that would remain undetected by the operator occurs from the primary makeup water through the CVCS system.
Isolating this potential dilution path or the OPERABILITY of the startup channel high neutron flux alarms, which alert the operator with sufficient time available to take corrective action, ensures that no loss of SHUTDOWN MARGIN and unanticipated criticality occur.
g The ACTION requirements specified in the event startup channel high neutron flux alarms are inoperable provide an alternate means to detect boron dilution by monitoring the RCS boron concentration to detect any changes.
The frequen-cies specified in Tables 3.1-1 through 3.1-5 provide the operator sufficient j
time to recognize a decrease in boron concentration and take appropriate correc-tive action without loss of SHUTDOWN MARGIN. More frequent checks are required with more charging pumps in operation due to the higher potential boron dilution rate.
The surveillance requirements specified provide assurance that the startup channel high neutron flux alarms remain OPERABLE and that required valve and electrical lineups remain in effect.
3/4.1.3 MOVABLE CONTROL ASSEMBLIES The specifications of this section ensure that (1) acceptable power distribution limits are maintained, (2) the minimum SHUTDOWN KARGIN is WATERFORD - UNIT 3 B 3/4 1-3 AMENDMENT NO. 9 e
REACTIVITY CONTROL SYSTEMS 1
i BASES MOVABLE CONTROL ASSEMBLIES (Continued) maintained, and (3) the potential effects of CEA misalignments are limited to acceptable levels.
The ACTION statements which permit limited variations from the basic requirements are accompanied by additional restrictions which ensure that the original design criteria are met.
The ACTION statements applicable to a stuck or untrippable CEA, or to a l
large misalignment (greater than or equal to 19 inches) of two or more CEAs, require a prompt shutdown of the reactor since either of these conditions may be indicative of a possible loss of mechanical functional capability of the CEAs and in the event of a stuck or untrippable CEA, the loss of SHUTDOWN MARGIN.
CEAs that are confirmed to be inoperable due to problems other than addresed by ACTION a. of TS 3.1.3.1 and that are trippable, will not impact SHUTDOWN MARGIN as long as their relative positions satisfy the applicable alignment requirements.
For small misalignments (less than 19 inches) of the CEAs, there is (1) a small effect on the time dependent long-term power distributions relative to those used in generating LCOs and LSSS setpoints, (2) a small effect on the available SHUTDOWN MARGIN, and (3) a small effect on the ejected CEA worth used in the safety analysis.
Therefore, the ACTION statement associated with trippable but small misalignments of CEAs permits a 1-hour time interval during
[
which attempts may be made to restore the CEA to within its alignment requirements.
The 1-hour time limit is sufficient to (1) identify causes of a misaligned CEA, (2) take appropriate corrective action to realign the CEAs, and (3) minimize the effects of xenon redistribution.
Problems may also cause more than one control rod to be immovable where the control rods continue to be trippable.
With trippable but multiple inoperable rods:
the alignment limits and restriction on THERMAL POWER in accordance with the provisions of Specification 3.1.3.6 for insertion limits, assures fuel rod integrity during continued operation.
These provisions are sufficient to allow 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to restore the inoperable rods to operable status when it is confirmed that the cause of the immovable rods is an electrical problem in the rod control system or an electrical or mechanical problem with the rod stepping mechanism exclusive of the rod holding coil that must function for a reactor trip.
In such cases, the control rods will continue to be capable of fulfilling their primary safety function.
The CPCs provide protection to the core in the event of a large misalign-ment (greater than or equal to 19 inches) of a CEA by applying appropriate penalty factors to the calculation to account for the misa11gned 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 SHUT-DOWN 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 associated with the large misalignment of a CEA requires a prompt realignment of the misaligned CEA.
WATERFORD - UNIT 3 B 3/4 1-4 AMENDMENT NO. 81
REACTIVITY CONTROL SYSTEMS BASES MOVABLE CONTROL ASSEMBLIES (Continued)
The ACTION statements applicable to trippable but 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 LC0 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.
Operability of at least two CEA position indicator channels is required to determine CEA positions and thereby ensure compliance with the CEA alignment and insertion limits.
The CEA " Full In" and " Full Out" limits provide an addi-tional independent means for determining the CEA positions when the CEAs are at either their fully inserted or fully withdrawn positions.
Therefore, the ACTION statements applicable to inoperable CEA position indicators permit l
