Attachment 1-ST IIL AE 3861 Page 1 of 4 SIGNIFICANT llAZARDS EVALUATION FOR A PROPOSED CllAN9E TO TiiE AUXILIARY TEEDWATER STORAGE TANK (AFST) MINIMUM VOLUMb REQUIREMENT Hackground The Auxiliary Feedwater (APW) system provides an independent means to supply feedwater to the steam generstors whenever the main feedwater system is not available. The AFW System also functions as an Engineered Safety Features Actuation-System component and is designed to function during a main feedwater line break (HFLB), main steam line break (MSLS), loss of offsite power (LOOP),
and loss of coolane accident (LDCA).
Under the above accident conditions, the APW system is designed to permit operation at hot standby for at least four hours, followed by a cooldown to RilR cut-in conditions. The RilR system continues the cooldown to cold shutdown conditions.
During the development of Draft Technical Specifications for STPEGS, a calculation.was performed assuming 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> at hot standby with a 10 hour1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> natural circulation cooldown. This was followed by an 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> soak period which prevented the formation of a steam bubble in the reactor vessel head. The calculation required 360,000 gallons for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> at hot standby and 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> of cooldown. The 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> soak time required 85,000 gallons and the volume of water spilled from a postulated faulted steam generator was 20,250 gallons Volumes were also derived to prevent vortex formation (13,100 gallons), the volume required for seal Icakage (16,800 gallons) and to account for an instrument.
-error of 24 (12,500 gallons). The unusable volume (10,400 gallons) of the AFST along with the above requirements resulted in-a total calculated Technical Specification volume of 518,050 gallons. This calculated volume for the AFST was used in Draft Technical Specification 3.7.1.3 and is the basis for the current Technical Specification 3.7.1.3 minimum required volume for the AFST, This calculation was overly conservative. The 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> soak period is not required to prevent a steam bubble in the reactor vessel head, In NUREG 0781 Supplement No. 3, Section 5.4,7 the NRC staff accepted the position that a 8 hour9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> soak time is not required. The reactor vessel head vent can be operated during the cooldown to' promote upper head cooling which in conjunction with a
- 25"F/hr cooldown will eliminate the need for upper head soak. Qualified
-instrumentation (upper head thermocouples) is used to determins when the head vent should be operated.

1 Attachment 1 ST HL AE 3861 Page 2 of 4 froblem Description The Auxiliary Feedwater Storage Tank (AFST) has a high alarm level of 516 inches of water. The current low alarm is set just above the Technical )
Specification limit of 518,000 gallons t.t 504 inches of water. This provides 12 '
inches of water for an operating range which requiros' manual level control instead of automatic level control. Manual filling of the tank has caused the AFST to overflow. This overflow violates water quality discharge Ilmits and requires an Exceedence Notification to be filed with the State of Texas and the Envirotunental Protection Agency.
This narrow operating range does not provide advance warning to thi '
operator that a Technical Specification limit is being approached. When the AFST in at a low level (518,000 gallons) the plant is placed in the Action Statement for Technical Specification 3.7.1.3. This results in entry into a Limiting Condition for Operation Action Statement. As a result of this problem, HL&P re evaluat1d the AFST minimum volume requirement.
AFST Minimum Vplume Reouirement Safety Evaluation A series of calculations vere performed to evaluate the possibility of a-reduction f.n~the required minimum level in the AFST. These calculations would ;
determinu the maximum amount of AFW required to cool the RCS to RHP. cut in conditions. The calculations determined that the AFST Technical Specification can he reduced to 485,000 gallons and permit operation at hot shutdown for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> followed by cooldown to the RHR cut in temperat .a. This can be performed from the control room using only safety grade equipment and assuming the worst case single active failure. The calculations evaluated four cases which are summarized in Attachment 2.
EKpoosed Shgggg e
HL&P proposes to change the minimum AFST water volume, as specified in Technical Specification 3.7.1.3 from $18,000 gallons to 485,000 gallcns. A mark up of Technical Specification 3.7.1.3 is in Attachment 4.

established in 10CFR50.92. This analysis has determined that: f f
- 1. The proposed change does not involve a significant increase in the j probability or consequences of an accident previously evaluated. The t
proposed change cannot increase the probability of a previously j evaluated accident because the AFST has no accident initiation l potential. The proposed change has been evaluated by analysis and the I bounding events have been chosen to assure that the AFST has an !
adequate volume of water prior to RilR cut in. No AFW performance !
parameters are affected; therefore, the consequences of a previously i evaluated accident do not increase. ;
i
- 2. The proposed change does not create the possibility of a new or ;
different kind of accident from any previously evaluated. The purpose i of the AFST is to mitigate an accident and the proposed level change j can not create the possibility of a new or different accident. The [
limiting reenaries were analyzed and the proposed Technical ;
Specification value was chosen to ensure that adequate AFST volume is i available for previously evaluated accidents. [
- 3. The proposed change does not involve a significant reduction in the l margin of safety. The originel analysis utilized overly conservative l assumptions in the calculation of the AFST required volume which [
resulted in a Technical Specification minimum required AFST volume of ;
518,000 gallons. l i
The current analysis determines the water requirements for various [
accident scenarios which are combined with water losses for the range ;
of aingle failures postulated. This results in a litriting case of l 471,000 gallons. The current analysis is more accurate while [
remaining conservative and conforms with the regulatory requirements. ,
i Margin of safety can be defined as the difference between the ultimate -
failure and the NRC acceptance criteria. Since the currenc analysis !
stays within the NRC acceptance criteria (SRP 10.4.9) the proposed !
change does not involve a significant reduction in the margin of ,
safety. [

Attactument 1 ST ilL AE 3861 Page 4 of 4 Irwiementation This proposed Technical Specification change can be iteptemented when the change is approved by the NRC.
Conclusion lil4P has performed an analysis to determine the ininimwn required volume
~for the ATST. IllAP proposes that the proposed change be approved.
