SDM B 3.1.1 B 3.1 REACTIVITY CONTROL SYSTEMS B 3.1.1 'SHUTDOWN MARGIN (SDM)

BASES BACKGROUND ' According to GDC 26 (Ref. 1), the reactivity control systems must be redundant and capable of holding the reactor core subcritical when shut down under cold conditions. Maintenance of the SDM ensures that

,.1. .-

postulated reactivity events will not damage the fuel.

'SDM requirements provide sufficient reactivity margin to ensure that acceptable fuel design limits will not be exceeded for normal shutdown and anticipated operational occurrences (AOOs). As such, the SDM

'defines the degree of subcriticality that would be obtained immediately following the insertion or trip of'all shutdown and control rods, assuming that the single rod cluster control assembly of highest reactivity worth is fully withdrawn.

The system design requires that two independent reactivity control systems be provided, and that one of these systems be capable of maintaining the core subcritical under cold conditions. These requirements are provided by the use of movable control assemblies and soluble boric acid in the Reactor Coolant'System (RCS). The Rod Control System can compensate for the reactivity effects of the fuel and water temperature changes accompanying power level changes over the range from full load to no-load. In addition, the Rod Control System, I together with the boration system, provides the SDM during power operation and is capable of making the core subcritical rapidly enough to prevent exceeding acceptable fuel damage limits, assuming that the rod of highest reactivity worth remains fully withdrawn. The soluble boron system can compensate for fuel depletion during operation and all xenon burnout reactivity changes and maintain the reactor subcritical under cold conditions. g al During power operation, SDM control is ensured by operating with the shutdown banks fully withdrawn and the control banks within the limits of LCO 3.1.6, "Control Bank Insertion Limits." When the unit is in the shutdown and refueling modes, the SDM requirements are met by means of adjustments to the RCS boron concentration.

SDM B 3.1.1 BASES APPLICABLE The minimum required SDM is assumed as an initial condition in safety SAFETY ANALYSES analyses. The safety analysis.(Ref. 2) establishes an SDM that ensures specified acceptable fuel design limits are not exceeded for normal operation and AOOs, with the assumption of the highest worth rod stuck out on a reactor trip.

The acceptance criteria for the SDM requirements are that specified acceptable fuel design limits are maintained.. This is done by ensuring that:

a. The reactor can eventually be made subcritical from all operating conditions, transients, and Design Basis Events;

b. The reactivity transients associated with postulated accident conditions are 'co'trollable within acceptable limits (departure from nucleate boiling ratio (DNBR), fuel denterline'temperature limits for A0Os, and 5 280 cal/gm eriergy deposition for the rod ejection accident); and '

c. The reactor will be maintained sufficiently subcritical to preclude inadvertent criticality in'the shutdown, condition.

One limiting accident for the SDM requirements is a main steam line break (MSLB) in Mode 2, as described in the accident analysis (Ref. 2). I The increased'steam flow resulting from a pipe break in the main steam system causes an increased energy removal from the affected steam generator (SG), and corisequently the RCS. This results in a reduction of the reactor' coolant temperature. The resultant coolant shrinkage causes a reduction in pressure.' In the presence of a negative moderator temperature coefficient, this 'cooldown'causes an increase in core reactivity. As RCS temperature decreases, the' severity of an MSLB decreases. The most limiting MSLB,'with respect to potential fuel damage before a reactor trip occurs,' is a break' of a main steam line upstream of the Main Steam Isolation Valve initiated'at the end of core life. The positive reactivity addition from the moderator temperature decrease will terminate when the affected SG boils,dry, thus terminating I. .

RCS'heat removal and cooldown., Following the MSLB, a post-trip return-to-power may occur; however, no fuel damage occurs as a result of the post-trip return-to-power, and THERMAL POWER does not violate the Safety Limit (SL) requirement of SL 2.1.1.'

A potentially more limiting MSLB accident could occur for a steam line break outside containment when in Mode 3 with the low pressurizer pressure signal for safety injection actuation blocked. In this scenario, feedwater would not automatically isolate and the, peak heat fluxes associated with the return-to-power may increase to values significantly greater than those in the accident analysis (Ref. 2). Therefore, when Catawba Units 1 and 2 B 3.1.1-2 Revision No. I

SDM B 3.1.1 BASES APPLICABLE SAFETY ANALYSES (continued) ,, -

safety injection is blocked, administrative controls on boron concentration are required to prevent a post-trip return-to-power.

Another limiting 'event for the SDM requirements is the inadvertent boron dilution event. The postulated reduction in the moderator boron concentration causes an insertion of positive reactivity. This positive reactivity insertion, if not terminated by operatorbor automatic action, would eventually cause a return to criticality and p6tentially to power operation. The 'expected method of stopping a dilution event initiated from a shutdown'condition is the Boron Dilution'Mitigation System (BDMS). However, in the event the BDMS is not OPERABLE, the safety analyses rely on operator action. MODE 5, because of its combination of a lower RCS liquid volume, which results in a faster dilution, and the lowver sbM limit, is the' limitin'g operational m ode foe this accident. The licensin'gbasis acceptance criterion is that the operator has at least fifteen minutes available,'from the time he is alerted to the occurrence of a dilution event (by the High' Flux at Shutdown alarm) to the time of criticality, to terminate the dilution. The most limiting boron dilution is one initiated at the beginning of core life since the high RCS boron concentrations at that burnup are more easily reduced, resulting in a larger concentration change per unit of time and therefore, a faster

'positive reactivity insertion. In order to meet the fixed operator action time criterion for delaying criticality, this faster dilution may be compensated for by a'larger SDM (Ref. 4).

'Inaddition tithe limiting MSLB transient, the SDM requirement must also protect against:' '" r '

a. An uncontrolled rod withdrawal from' subcritical or low power condition; and

b. Rod ejection.

Each of these events is discussed below.

Depending on the system initial coriditions 'and 'reactivity insertion rate, the uncontrolled rod withdrawal transient is terminated by either a high

' power level trip or a high pressurizer pressure trip. 'In all cases, power level, RCS pressure, linear heat rate,' and the DNBR do not exceed

-allowable limits.

The ejection of a control rod rapidly adds reactivity to the reactor core, causing both the core power level and heat flux to increase with corresponding increases in reactor coolant temperatures and pressure.

The ejection of a rod also produces a time dependent redistribution of core power. SDM satisfies Criterion 2 of 10 CFR 50.36 (Ref. 3). Even Catawba Units I and 2 B 3.1.1-3 Revision No. I

SDM B 3.1.1 BASES APPLICABLE SAFETY ANALYSES (continued) though it is not directly observed from the'control room, SDM is considered an initial condition' process variable because it is periodically monitored to ensure that the, unit is operating within the bounds of accident'analysis assumptions.

Transients which are made less severe by the rapid insertion of control rod negative reactivity are also affected by the magnitude of the SDM limit. This is because the safety analyses assume a change in the rate of insertion of this negative reactivity when the SDM limit is reached. While the SDM is less than the limit value, the negative reactivity from the control rods is assumed to be inserted'as.quickly as the rod worth vs.

time curves shown in Reference 5. When the SDM limit value is reached, the rate of negative reactivity insertion is decreased so that it is only fast enough' to compensate for any positive reactivity insertion, e.g., from the cooling of the fuel and 'moderator (which ndr'mally have negative temperature coefficients). This methodology is conservative in that it does not take credit in the safety analyses,' even temporarily, for a SDM greater than the' limit'value.

LCO. SDM is a core design condition that can be ensured during operation through control rod positioning (control and shutdown banks) and through the soluble boron concentration.

The MSLB (Ref. 2) and the boron dilution (Ref. 4) accidents are the most limiting analyses'that establish the SDM value 'of the LCO. For MSLB accidents, if the LCO is violated, there is a potential to exceed the DNBR limit and to exceed 10 CFR.100, "Reactor Site Criteria," limits (Ref. 5).

For the boron dilution accident, if the LCO is violated, the minimum

' -required time assumed for operator action to terminate dilution may no longer be applicable.

APPLICABILITY In MODE 2 with keff < 1.0 and in MODES 3, 4, and 5, the SDM requirements are applicable to provide sufficient negative reactivity to meet the assumptions of the safety analyses discussed above. In MODE 6, the shutdown reactivity requirements are given in LCO 3.9.1, "Boron Concentration." In MODES 1 and 2 with keff > 1.0, SDM is ensured by complying with LCO 3.1.5, "Shutdown Bank Insertion Limits,~'

and LCO 3.1.6.

SDM B 3.1.1 BASES K. ACTIONS A.1 - i, -

If the SDM requirements are not met, boration must be initiated promptly.

A Completion Time of 15 minutes is adequate for an operator to correctly align and start the required systems and c6mponents. It is assumed that boration will be continued until the SDM requirements are met.

In the determination of the'required combination of boration flow rate and boron concentration, there is no unique requirement that must be satisfied. Since it is impe'rative to raise the boron concentration of the RCS as soon as possible, the boron concentration should be a highly concentrated solution, sucha's that normally found in the boric acid storage tank, or the refueling water storage tank. The operator should borate with the best source available for thb'plant conditions.

In determining the boration flow rate, the time in core life must be considered. For instance,.the most difficult time in core life to increase the RCS boron concentration is at the beginning of cycle when the boron concentration may approach or'exceed 2000 ppm. Using its normal makeup path',"the Chemical and Volirme' Control System (CVCS) is capable of inserting negative reactivity at a rate of approximately 30 pcm/min when the RCS boron concentration is 1000 ppm and approximately 35 pcm/min when the RCS boron concentration is 100 ppm. If the emergency boration path is used,'the CVCS is capable of' inserting negative reactivity at the rate of 65 pcm/min when the RCS boron concentration is 10900pm and 75 pcm/min when the RCS boron concentration is 100 ppm. Therefore, if SDM had to be increased by 1%

Ak/k oro1000 pcm, normal makeup path'at 1000 pprmi could restore SDM in approximately 33 minutes.' A 100 ppm, SDM could be restored in approximately 29'rninutes. In the emergency boration mode at 1000 ppm, the 1% Ak/k could be restored in approximately 15 minutes. With--

RCS boron concentration at.100 ppm, SDM could be increased by.1000 pcm in approximately 13'minutes using emergency boration. These boration parameters represent typical values and are provided for the purpose of offering a specific example.'

REQUIREMENTS In MODES 1 and 2 with keff Ž 1.0, SDM is verified by observing that the requirements of LCO 3.1.5 and LCO 3.1.6 are met. In the event that a

'rod is known to be untrippable, however, SDM verification must account for the worth of the untrippable rod as well as another rod of maximum worth.

j' r SDM B 3.1.1 BASES SURVEILLANCE REQUIREMENTS (continued)

In MODE 2 with keff < 1.0 and MODES 3, 4, and 5, SDM is verified by performing a reactivity balance calculation, considering the listed reactivity effects:

a. RCS boron concentration;

b. Control bank position;

c. RCS average temperature;

d. Fuel burnup based on gross thermal energy generation;

e. Xenon concentration;

f. Samarium concentration; and

g. Isothermal temperature coefficient (ITC).

Using the ITC accounts for Doppler reactivity in this calculation because the reactor is subcritical, and the fuel temperature will be changing at the same rate as the RCS.

The Frequency of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is based on the generally slow change in required boron concentration and the low probability of an accident occurring without the required SDM. This allows time for the operator to collect the required data, which includes performing a boron concentration analysis, and complete the calculation.
