1.0 Purposo The purpose of this calculation is to document the design bases for operation of motor operated vatves (MOVs) N6150/151, the Power Operated Rehet Valve (PORV) block valves. These MOVs are contained in the Reacto Coolant System (RCS) and are included in the Fort Calhoun Nuclear Station Genenc Letter No. 8910 MOV Progtam. The design basis review involves the compilation of the design bases for operation of each MOV including maximum expected differentiel pressure (MEDP), maomum kne pressure (P.J, maximum flow rate (O), and maximum fluid temperatur9 (T).

2.0 Proceduro The procedure for performing the design basis review consists of dehning the MOV functions from the appropriate elementaries/ schematics, operating procedures,the USAR and other design basis docurnents. Based on the function dehnitions, cperating scenarios are developed for which the maximum expected pressure ano differential pressure are calculated. Scenarios from each apDlicable mode of cperation including normal operations, abnormal operations, design basis accident conditions, surveillance / test, and Emergency Operating Frocedures will be developed and the corresponding design basis flowrate and temperature will be documented.

FCS Updated Safety Analysis Report 1991 Submittal, Section 4 4.0 Systern Desenption in addition to the pressurizer which maintains pressure at 2100 psia during normal operation, the components of interest to the design bcses for operation of the PORV Block Valves within the j

Reactor Coolant System are the Power Operated Relief Valves, the Primary Safety Valves, and the l

Quench Tank. The two lORVs relieve sufficient pressurizer steam during plant transients to prevent opening of the safety valves [17]. PCRVs PCV 1021 and 2 are opened by the high primary system pressure reactor trip signal at 2385 psig (2400 psla). The set pressure of pressurizer safetles RC.141 and 142 are 2530 psig and 2485 psig respectively with a 1% tolerance.

The quench tank prevents RCS discharges from being released to the containment atmosphere unless the rupture disk setpoint is exceeded [6.17).

The PORV Block Valves are normally open during normal power operations to allow the PORVs to provide for overpressure protection. The block valves must be capable of closing during any plant condttien rf required to isolate a leaking or stuck-open PORV and remain closed to maintain i

reactor coolant pressure boundary integrity [6]. AdditionallV when closed, these valves may be called upon to open to provide low temperature overpressuro protection, or as an alternate means of depressurization for the mitigation of steam generator tube rupture and other design basis events, or to establish once through cenling upon loss of all feedwater, b@CN

Valves HCV 150/151 are considered posrtion changeable [2].

Functions' The design basis function of the PORV Bleck Vatves is to close to isolate the PORVs from the hCS during any plant condition whenever there is an indication of a leaking or stuck-open PORV to ensure the integrity of the reactor coolant pressure boundary [1,5,0j. Additionally, when closed, these varves may be required to open to support depressurization of the RCS for some postulated events [1]. Their required actions are:

1.

Close to isolate a leaking or stuck-open PORV to maintain RCS pressure boundary integrity [7.9].

2.

Verify open prior to RCS startup & remain open during normal power operations to allow the PORVs to provide for overpressure protection l13].

S.1 Normal Operations The PORV Olock Valves are normally open during power operations unless they are closed due to excessive leakage of the PORV, the PORV is stuck cpen or the PORV is inoperable for some other reason. A closing function considered under normal operations is to close for PORV maintenance an operation which is not performed at power. Since the PORV block valves are normally open dunng normal power operations, the applicable open function involves recovery i

from inadvertent closure.

MEDP.,,,,

1 The block valves are verthed open pnor to RCS startup and remain open dunng normal operations unless a PORV becomes inoperable due to excessive leakage. Assuming an inadvertent closure at power would result in an upstream and downstream pressure of 2100 psia (normal pressurizer i

pressure) and a O pst differential pressure to re-open.

!LCDL.s Assuming the block valve (s) were closed during power operation due to a leaking PORV, the block valves would be required to open to enable low temperature overpressurtzation protection (LTOP) during cooldown. LTOP is initiated when RCS pressure is less than or equal to 1050 psia 171. To account for instrument inaccuracy, this pressure is conservatively assumed to be 1700 psta (1650 + 3%). While the normaloperating pressure in the quench tank is 3 psig with a normal maximum of 1C psig [14). for conservatism a downstream pressure of 0 psig (14.7 psia) is assumed.

MEDP_

The PORV block valves are required to close to isolate the PORVs when conditions indicate abnormal RCS leakage, if high quench tank temperature, pressure, and/or level conditions are indicated. RCS pressure is verrfied to be less than 2300 psia prior to closing the PORV block valves (7). -To accouilt for instrument inaccuracy, the pressure is conservatively assumed to be 2309 psia (2300 + 3%) Since this scenario applies to a leaking PORV and not a stuck-open PORV. It is assumed that the PORVs are still able to hold back pressure on the block valves during closure. Therefore, th6 Jpstream and downstream pressure are essentially equivalent and the MEDP is zero.

Marimum Presture The maximum pressure of 2309 psia is present upstream and downstream of the valvo during this closing scenario, flow Condigns The flowrato due to a leaking PORV (as opposed to a stuck open PORV) is assumed to be within the limiting condition for operation for RCS leakage of 10 gpm [Ref. 5, Section 2.1.4].

5.3 Cesign Basis Accident Conditions The block va;ves must be capable of closing in the event of a stuck open PORV to limit the loss of RCS inventory. While the block vakau are used for certain EOP actions, there are no dni23 basis open scenarios for the PORV block valves. The accident conditions for which the block valves may be required to open are beyond the design bases of the plant.

MEDP__.

The maximum differential pressure associated with valve closure would occur following the pressure tra.isient which resulted in tha stuck-open PORV. The PORV reseating (blowdown) pressure is 2376 psia (2400 1%) assuming the PORV had not stuck open. However, there is no proceduralized operator action requiring the block valves to close until pressure is less than 2300 psia (10]. Neither the PORVs or the PORV block valves are required to close with pressurizer pressure at or near the tafety valve setpoint, nor is it practical to assume that an operator would attempt to close the blN 'alvat until pressure is satisfactorily rmced per the EOPs.

)

To account for instrument inaccuracy, the upstream pressure is conservatively assumed to be at 4

2369 psia (2300 + 3%). While tr e quench tank can condense the steam discharged auring a loss of load incident without exceeding the rupture oisk y,etpoht [tp lownstream containment atmosphere conditions (14.7 psia) are assumed for cransarvatism.

Maximum Pressure The maximum pressure associated with valve closure due to a stuck open PORV is the upstream pressure of 2369 psia.

D2w Conditions The maximum flow through KCV 150/151 associated with valve closure assuming a stucx open PORV is 110.220 lbs/hr assumrq saturated steam, the flow capacity of a FORV [6].

Temoerature Conditions The temperature of saturated steam at 2069 psia is 660 F [151 Stroke Time No design basis stoke time relative to this scenario applies,

5.4 Surveillanc6; Test -

To satisfy the requiremerits of the Technical Spec;fications, the PORV block valves are cycled during quanerly surveillance with the PORVs closed (8],

MEDP_

During surveillance stroke testing of the PORV block valves, the PORVs are closed (15], trapping pressurizer downstream of the block valves. Since the block valves are normally open, then closed and re-opened for the rtroke test, upstream and downstream pressure are essentialty equivalent during vatve op2ning. Nermal pressurizer pressure of 2100 psia is assumed [6,16].

Maximum Pressure The maximum pressure of 2100 osia is present upstream and downstream of the valve f aring valve opening.

1 5.5 Emergency Operating Procedures A potential EOP response to a loss of all feedwater requires the block valves to open (if closed due to a stuck-open PORV) to inrtiate once-through-cooling [12).

NEDP,

Since the PORV block valves are otherwise normally open, the maximum upstream pressure at whk.a the PORV block valves would be required to open would occur with the PORVs inoperable (stuck open) and the block valves closed for RCS isolation per the Technical Specifications [Ref.

5, Section 2.1.6]. Automatic pressure relief capability is provided by the safety valves and any manual operator action in response to a pressure transient would likely precede reaching the safety valve setpoint of 2500 psia. However, assuming a loss of all feedwater and initiation of once-through-cooling operations, the block valves could be required to open wrth pressure near the safety valve setpoint of 2500 psia [6,12].

Maximum Pressure 1

The maximum pressure associated with tN scenario is the upstream pressure of 2500 psia.

Flow Conditions After once-through cooling has been established, the flow through HCV 150/151 will be the combined flow of all available HPSI and charging pumps [12]. However, there is still a bubble in the pressurizer during the initiation of once-through cooling; therefore, the initial flow conditions during unseating will be saturated steam at 110.220 lbs/hr, the flow capacity of a PORV [6],

Temoerature Conditions The temperature of saturated steam at 2500 psia is 668*F [15].

Stroke Time No design basis stoke time relative to this scenaric applies.

SUBJECT:

Degraded Voltage Operation of the PORV Block Valves HCV-150 and HCV-151 The purpose of this memorandum is to pro */ide the results of an investigation into the expected motor terminal voltage during 4. DBA with degraded voltage on the 161 KV grid. This information was requested by R. J. Mueller to insure adequate thrust was available to close the block valve (s) should a PORV(s) stick open causing a LOCA.

The criteria provided by Mr. Hueller was 396 volts l

(90% of the motor 440v rating) to assure rated MOV thrust.

l l

The attached ELMS degraded voltage analysis indicates a worst case voltage of 408V for HCV-if0 (condition 3) and 396.5 volts for HCV-151 (condition 5).

These voltage correspond to the expected worst case bus loadings with the condensate system at full load, buses 1Al and 1A2 on the 161 KV and all safety loads sequenced on. The bus voltage on buses IA3 and 1A4 are at the OPLS setting which corresponds to approximately 158900 volts on the 161 KV g' rid.

Under these conditions, the 396 volt criteria is met.

Please noted that this calculation is not complete and the results are considered preliminary.

The approved calculation based on QP-3 including necessary reviews will be completed by 2/22/91.

If there are any questions, please contact Mr. R. F. Mehaffey at extension 3471.
