3/4.1 REACTIVITY CONTROL SYSTEMS BASES i

3/4.1.1 BORATION CONTROL 3/4.1.1.1 and 3/4.1.1.2 SHUTDOWN MARGIN A sufficient SHUTDOWN MARGIN ensures that (1) the reactor can be made subcritical from all operating conditions, (2) the reactivity transients associated with postulated accident conditions are controllable within acceptable limits, and (3) the reactor will be maintained sufficiently subcritical to preclude inadvertent criticality in-the shutdown condition.

SHUTDOWN MARGIN requirements vary throughout core life as a function of fuel depletion, RCS boron concentration, and RCS T,yg. The most restrictive condition occurs at E0L, with T,yg at no load operating temperature, and is i associated with a postulated steam line break accident and resulting uncon-trolled RCS cooldown. In the analysis of this accident, a minimum SHUTDOWN MARGIN of 5.15% delta k/k is required to control the reactivity transient.

Accordingly, the SHUTDOWN MARGIN requirement is based upon this limiting condition and is consistent with FSAR safety analysis assumptions. With T,yg

less than or equal to 200*F, the reactivity transients resulting from any postulated accident are minimal and a 2% delta k/k SHUTDOWN MARGIN provides adequate protection.
3/4.1.1.3 MODERATOR TEMPERATURE COEFFICIENT b

j The limitations on moderator temperature coefficient (MTC) are provided to ensure that the assumptions used in the accident and transient analysis remain valid through each fuel cycle. The Surveillance Requirements for measurement of the MTC during each fuel cycle are adequate to confirm the MTC i value since this coefficient changes slowly due principally to the reduction j in RCS boron concentration associated with fuel burnup. The confirmation that l

the measured MTC value is within its limit provides assurances that the coef-ficient will be maintained within acceptable values throughout each fuel cycle.

, subtritical immediately following a reactor trip, considering a single

. malfunction resulting in the highest worth CEA failing to insert.  ;

l The function of SHUT 00WN MARGIN is to ensure that the reactor remains j suberitical following a design basis accident or anticipated operational occurrence.

During operation in MODES 1 and 2, with k,ff greater than or equal to 1.0, the transient insertion limits of Specification 3.1.3.6 ensure that sufficient SHUTDOWN MARGIN is available.

SHUTDOWN MARGIN requirements vary throughout the core life as a function of fuel depletion and reactor coolant system (RCS) cold leg temperature (Teold)*

The most restrictive condition occurs at E0L, with T cold at no-load operating temperature, and is associated with a postulated steam line breek accident and the resulting uncontrolled RCS cocidown. In the analysis of this accident, the specified SHUTDOWN MARGIN is required to control the reactivity transient and ensure that the fuel performance and offsite dose criteria are satisfied.

As (initial) Tcold decreases, the potential RCS cocidown and the resulting reactivity transient are less severe and, therefore, the required SHUTDOWN MARGIN also decreases. Below T cold of about 200*F, the inadvertent deboration event becomes limiting with respect to the SHUTDOWN MARGIN requirements.

Below 200'F, the specified SHUTDOWN MARGIN ensures that sufficient time for operator actions exists between the initial indication of the deboration and the total loss of'3Htff00WN MARGIN. Accordingly, the SHUTDOWN MARGIN requirements are based upon these limiting conditions.

Additional events considered in establishing requirements on SHUTDOWN MARGIN

DESCRIPTION AND SAFETY ANALYSIS OF PROPOSED CHANGE NPF-38-41 This is a request to revise section 3/4.10.1, SPECIAL TEST EXCEPTIONS, SHUTDOWN MARGIN of the Technical Specifications for Waterford Steam Electric Station Unit 3.

Existing Specification See Attachment A.

Proposed Specification See Attachment B.

Description The proposed amendment would modify Technical Specification 3/4.10.1, SPECIAL TEST EXCEPTIONS, SHUTDOWN MARGIN.

Technical Specification 3.10.1 presently allows shutdown margin to be reduced to less than the normal operating shutdown margin requirements during low power physics testing provided that certain conditions are satisfied. One of these conditions (Surveillance Requirement 4.10.1.2) stipulates that all CEAs not fully inserted in the core be shown to be capable of full insertion when tripped from at least the 50% withdrawn position within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> prior to reducing the shutdown margin to less than normal operating requirements. The requested revision would allow this surveillance to be performed within 7 days of the

, shutdown margin reduction instead of within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> as presently required.

This modification is proposed to allow low power physics testing to be accom-plished without an additional reactor trip to verify CEA insertability. The startup test pro CEA drop timesreference (gram includes a CEA Technical trip test before Specification criticality 3.1.3.4). to measure Following these measurements, criticality is achieved and low power physics tests are performed, CEA integral reactivity worths are determined during this testing sequence and may require reduction of shutdown margin as permitted by Technical Specification 3.10.1. Since the worth measurements are typically performed several days after the CEA drop time measurements, the reactor must be tripped to verify CEA insert-ability and satisfy Surveillance Requirement 4.10.1.2. The requested revision would therefore eliminate the need for an additional reactor trip during low power physics testing by requiring verification of CEA insertability within 7 days of reducing the shutdown margin instead of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.

The primary consideration in extending the surveillance time period for verifying CEA insertability is whether there would be a significant increase in the prob-ability of a stuck CEA during the 7 day period of time as compared to the present 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> time period. Consideration of the configuration of the components that are used in CEA insertion indicate that there is nothing which could cause a significant increase in the probability of a CEA becoming stuck. This is due to the fixed geometry of these components over the 7 day period that could elapse I

NS41169

between rod drop time measurements and shutdown margin reduction. The components considered include the fuel assembly, the CEA, the CEA extension shaft, the control element drive mechanism and the upper guide structure. Also, since the CEAs will insert upon loss of power, the probability of a stuck CEA is not increased due to an electrical malfunction.

This change is similar to changes issued to other CE plants.

Safety Analysis The proposed change described above shall be deemed to involve a significant hazards consideration if there is a positive finding in any of the following areas:

1. Will operation of the facility in accordance with this proposed change involve a significant increase in the probability or consequences of any accident previously evaluated?

Response: No.

The proposed change does not remove the trip surveillance requirement.

It merely allows for a 7 day surveillance requirement rather than the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> surveillance requirement. During this interim, there would be no significant increase in the probability of a stuck CEA since there is nothing occurring during this period which would alter the fixed geometry of the components associated with the rod drop time measurements. There-fore, the proposed change will not involve a significant increase in the probability or consequences of any accident previously evaluated.

2. Will operation of the facility in accordance with this proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No.

This revision addresses a change in a surveillance requirement and as such, no new failure or accident path is created. Consequently, there will be no creation of a new or different kind of accident from any accident previously evaluated.

3. Will operation of this facility in accordance with this proposed change involve a significant reduction in margin of safety?

Response: No.

Although the trip surveillance requirement is relaxed from 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to seven days, there is no significant increase in the probability of a stuck CEA with the new surveillance requirement. As such, this change will not include a significant reduction in margin of safety.

l

Safety and Significant Hazards Determination Based on the above Safety Analysis, it is concluded that (1) the proposed change does not constitute a significant hazards consideration as defined by 10 CFR 50.92; (2) there is reasonable assurance that the health and safety of the public will not be endangered by the proposed change; and (3) this action will not result in a condition which significantly alters the impact of the station on the environment as described in the NRC Final Environmental Statement.

NPF-38-42 DESCRIPTION AND SAFETY ANALYSIS OF PROPOSED CHANGE NPF-38-42 This is a request to revise section 3/4.10.3, SPECIAL TEST EXCEPTIONS, REACTOR COOLANT LOOPS of the Technical Specifications for Waterford Steam Electric Station Unit 3.

Existing Specification See Attachment A.

Proposed Specification See Attachment B.

Description The proposed amendment would modify Technical Specification 3/4.10.3, SPECIAL TEST EXCEPTIONS, REACTOR COOLANT LOOPS.

In order to perform certain physics tests at low thermal power levels, it is necessary to bypass the core protecticn calculators. This is accomplished by manually bypassing the calcu}ators after increasing the CPC operating bypass permissive setpoint from 10 % power to a value that will allow physics testing to take place without incurring a DNBR - Low or LPD - High reactor trip. This adjustment is made to a bistable setpoint in the log power circuitry.

Concurrently, Technical Specification 3.10.3.b requires that the Linear Power Level - High trip setpoint be decreased to less than or equal to 20% RATED THERMAL POWER. This provides additional assurance that a reactor trip will occur in the event of an unplanned power excursion while the operating bypass permissive setpoint is set to a higher than normal value.

The addition of Technical Specification 3.10.3.c is being proposed to provide an alternate means of ensuring a reactor trip prior to exceeding the present limit for physics testing at low thermal power levels. The CPC operating bypass permissive bistable serves the dual function of permitting the Log Power Level -

High trip to be manually bypassed when the thermal power exceeds the operating bypass permissive setpoint. If the permissive setpoint is increased to a value greater than the Log Power Level - High trip setpoint specified in Table 2.2-1 of Technical Specification 2.2.1, then a Log Power Level - High reactor trip will occur if an unplanned power excursion takes place during physics testing.

Therefore, the Log Power Level trip function may be used in place of the Linear Power Level trip function to provide additional assurance that a reactor trip will occur in the event of an unplanned power excursion during physics testing.

Safety Analysis The proposed changes described above shall be deemed to involve a significant hazards consideration if there is a positive finding in any of the following areas:

NS41168

1. Will operation of the facility in accordance with this proposed change involve a significant increase in the probability or consequences of any accident previously evaluated?

Response: No.

This change increases the power level at which the CPC's enable the DNBR - Low and LPD - High reactor trips. Protection however is still provided through this increase by the Log Power Level - High reactor trip. Since ample protection is still supplied, there will not be any significant increase in the probability or consequences of an accident previously evaluated.

2. Will operation of the facility in accordance with this proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?

Response: No.

Although this change alters the range of application for certain trips, proper core protection is still supplied. No other functional changes are made to these trips; consequently, this change can not create nor involve a new path which may lead to a new or different kind of accident.

3. Will operation of the facility in accordance with this proposal involve a significant reduction in a margin of safety?

Response: No.

As stated above, a change has been made altering the range of applica-tion for certain trip functions. Protection, however is still provided for over this increase. Since there will be no reduction in trip cover-age, this proposed change can not involve a reduction in a margin of safety.

Safety and Significant Hazards Determination Based on the above Safety Analysis it is concluded that (1) the proposed change does not constitute a significant hazards consideration as defined by 10 CFR 50.92; (2) there is reasonable assurance that the health and safety of the public will not be endangered by the proposed change; and (3) this action will not result in a condition which significantly alters the impact of the station on the environment as described in the NRC Final Environmental Statement.
