1.0 INTRODUCTION

This assessment was performed to determine the differential pressure capability of the primary containment purge valves should they be required to isolate during a LOCA event.

The assessment results will establish that the existing Inservice Inspection Program and Technical Specification limits on valve closure time are adeouate to ensure valve operability.

In their review of the Fermi 2 purge and vent valve operability demonstration, the Nuclear Regulatory Commission (NRC) indicated (Reference 2) that a maximum O'-

allowable stroke time should be established for the 10" and 24" valves for the " inservice test" conditions, i.e.,

no load stroke timing.

The NRC felt that an allowable inservice testing time limit, more restrictive than the Plant Technical Specification, may have to be established to ensure that unacceptable torque loads will not develop on these valves during a LOCA when the primary containment is pressurized.

Detroit Edison requested MDC's assistance in establishing the differential pressure capability of the purge valves and evaluating the need for a more rentrictive limit on the closure times measured during inservice inspection (no load condition).

Section 2.0 of this report discusses MDC's evaluation approach.

The details of the evaluation are presented in Section

("'

3.0.

The evaluation results and conclusions are

's-presented in Sections 4.0 and 5.0, respectively.

SUMMARY

OF THE EVALUATION APPROACH The approach which was applied in establishing the differential pressure capability of the 10" and 24" Jamesbury butterfly valves is outlined as follows:

(1)

The loads and load combinations which were applied in the original Jamesbury stress report (Reference

3) were re-established.

OV (2)

A non-mechanistic, peak dynamic torque value was established corresponding to the primary containment design pressure of 56 psig and the maximum toraue coefficient (i.e., CT (90*)).

(3)

The new predicted stresses and stress margins for the shaft, bracket, bracket bolts, and body neck were conservatively determined by increasing the total stress values reported in the Jamesbury stress report in proportion to the peak dynamic torque-to-valve breaking torque ratio.

I (4)

The realistic net toraue values that the valve l

would experience while closing during a postulated DBA event were assessed to establish the conservatism in applying the computed peak

dynamic toraue.

(5)

The results from above evaluation steps were used to confirm that valve closure time measured during testing or no load conditions need not be more restrictive than the Inservice Inspection Program requirements.

3.0 EVALUATION The original stress reports evaluated the major components of the valves, the results of which are shown in Table 1.

These stress levels represent the combined stresses due to seismic loading, valve disc

(~'

pressure, and valve " breaking" torque (the toroue k-required to either seat or unseat the valve).

The breaking torques used in the stress report for the 10" and 24"O valves were 730 f t-lbs and 3200 f t-lbs, respectively.

The allowable stresses used are those reflecting faulted loading conditions (Level-D allowables) in accordance with the applicable codes and are appropriate for the analysis of LOCA plant conditions.

The original stress report did not include the dynamic torque exerted on the valve by the compressible flow of drywell gases during a LOCA.

The dynamic torque on the valve can be determined by the method outlined in the Purge Valve Closure Analysis (Reference 1) which is based on the Fermi 2 drywell LOCA pressure ramp and torque versus closure angle information developed by the manufacturer.

As indicated in Reference (2)

if for some reason the closure of the 10" and 24" valves is delayed during a LCCA, the NRC is concerned that high drywell pressure would induce net torques on the valves in excess of the torques used in the original stress report.

This possibility implies that a time limitation should be placed on these valves during inservice testing to ensure that the differential pressure capability of the valves will not be exceeded.

The intent of the following evaluation is to investigate the stress levels on the 10" and 24"@

O' valves resulting from the greatest predictable drywell differential pressure, and determine if those stresses are within allowables and contain sufficient margin to eliminate any need for closure time limitations during inservice testing.

3.1 Stress Levels Resulting from Dynamic Toraue For this analysis, the drywell design pressure of 56 psig is assumed.

According to BTP-CSB 6-4, "Contain-ment Purging During Normal Plant Operation" and as reflected in the Fermi 2 Technical Specifications, the j

maximum allowable purge valve closing time is 5 seconds.

Realistically, the requirements of the Inservice Inspection Program will ensure valve closure l

prior to 5 seconds (see Article 3.3).

Using the 5-second interval, the predicted post-LOCA drywell r'"s pressure would ramp up to only 50 psig (see Reference

\\--

1, Figure 1).

Therefore, using the drywell design 1

pressure as basis for stress level evaluation is a very conservative assumption.

Dynamic torque on the valve is given by the expression, 3

TV = CT(6 ) ApD where TV = dynamic valve torque (ft-lbs)

CT = toroue coefficient (a function of valve closure angle $ )

Ap = differential pressure (psi) = 56 psi D

= nominal valve diameter (inches)

Using the Reference (1) toraue coefficient curves A and B for the 24 inch and 10 inch valves respectively, at a closure angle of 90 degrees (valve fully open, at which point the maximum dynamic torque is developed for the 4

constant drywell pressure condition assumed in this analysis), the resulting dynamic toraues are:

TV (24") = 6600 ft-lbs TV (10")

800 ft-lbs

=

Torcue coefficient curves A and B are applicable since Detroit Edison has installed all of the purge valves such that the shaft is in-plane relative to the upstream elbow.

The dynamic torques have been compared with the torques used in the original stress report, g-~

730 The original stress levels (7p and Tmax) determined in the original stress report are presented in Table 1.

These values were then increased by the above factors and compared to the allowables.

These results are tabulated in Table 2.

It should be emphasized that this method of comparison results in a very conservative estimate of new stress values resulting from the dynamic torque, because the stresses originally computed were due to seismic loads and disc pressure loads, in addition to the pure torque loads.

By amplifying the original stress values by the above factors, the seismic and disc pressure stresses are being amplified as well as the torque stresses.

In addition, the disc pressures originally calculated were conservatively, based on drywell pressures greater than 56 psi (62 psi for the 24 inch velve, and 150 psi for the 10 inch valve).

As can be seen from Table 2, the resulting stresses are still well within allowables.

3.2 Net Valve Toroue The pneumatic valve operatorn consist of a spring-loaded piston linked to the valve shaft.

Air on the forward side of the piston compresses the spring and holds the valve open.

The valves are closed by the spring when the pressure side of the piston is vented.

In applying a more realistic valve closure analysis, force components due to spring force, piston back pressure, valve friction and dynamic torque all act upon the valve, resulting in a total net torque applied to the shaft.

Using the Reference (1) mathematical model, an analysis was done to determine the maximum net torque the valves would experience through a closure cycle during a LOCA event.

The Reference (1) drywell post-LOCA pressure versus time and torque coefficient versus velve position response curves were used in the analysis.

The results are:

Net Torque (10" valve) = 1,315 ft-lbs Net Torque (24" valve) = 3,130 ft-lbs di The net torque in the 24" valve is approximately one-half of the dynamic torque used to evaluate stresses reported in Table 2.

It can therefore be concluded that the net torque on the 24" valve throughout the closure cycle will not exceed the peak dynamic toruue used in the Section 3.1 assessment, and that the stress levels calculated in Section 3.1 which

represent very conservative maximums, will not be exceeded.

The maximum net torque on the 10" valve exceeds the peak dynamic torque used to evaluate stress levels in Section 3.1.

Therefore, a new amplification factor was computed based on the maximum net torque.

10" net torque ratio = 1315 = 1.80 730 A

/%

The originally computed stress levels were then multi-plied by this factor, and are shown in parentheses in Table 2.

As can be seen, the resulting stress levels are still well below the allowables.

Considering that the original stresses included seismic and conserva-tively established pressure loads as well as the torsional loads (as discussed in Section 3.1), it is concluded that the components of the 10" valve will not be overstressed during post-LOCA closure.

3.3 valve Closure Limits j

Utilizing the BTP-CSP 6-4, " Containment Purging During Normal Plant Operation", the maximum allowable purge valve closing time would be 5 seconds.

However, the inservice test requirements defined by ASME Boilet and l

Pressure Vessel Code,Section XI, Article IwV-3417 will I

realistically result in more restrictive closure limits

{}

for the Fermi 2 primary containment purge valves.

The as-received full stroke times for these purge valves are well less than 5 seconds.

Therefore per Article IWV-3417 of the ASME Code, an increase in stroke time of 50% or more from the previous test will require the test frequency to be increased to once a month until corrective action has been taken.

It is expected that over time, gradual degradation'of closure time may result from reductions in cylinder spring force, increase solenoid valve opening times and/or increases in surface friction coef ficients.

! (}

However, if a full 50% degradation in closure time were to occur in any one test, there would still be ample margin between the degraded valve performance condition and the maximum allowable purge valve closing time of 5 seconds.

In addition, the required increase in testing frequency will ensure that the valve closing speed is less than the maximum 5 second allowable until corrective action can be instituted.

~

4.0 RESULTS Reproportioning the originally computed stresses, baced on the dynamic valve torques developed from the drywell design pressure of 56 psig and net torque valves during closure, results in stress levels that are still within allowables, as shown in Table 2 and the preceeding discussions.

The margins remaining between the new predicted stress levels and the

N (N

allowables range from approximately 10 percent to approximately 80 percent of the allowable stresses.

_ CAPABILITIES ngVISION-1 PAGE 10 These margins are more than adequate to overcome any additional stresses caused by normal wear of the moving valve components.

In addition, the requirements of the Inservice Inspection program will ensure that any conditions leading to extended closure times are identified and necessary corrective actions instituted.

The results also indicate that the AP capability of the valves exceeds the maximum AP that would be experienced at any time during a DBA and the valves would be expacted to close reliably without damage from j

^S overstressing.

J' l

The results are reinforced by the conservatisms used in i

the evaluation, namely:

(1)

A non-mechanistically determined drywell differential pressure (56 psig) was assumed to act across the valve throughout closure, when in reality the drywell pressure ramps up from near zero to a peak value of less than 50 psig af ter 5 seconds, by which time the valve is normally closed.

(2)

The original stresses that were amplified in proportion to the maximum dynamic torque were not pure toraue-related stresses, but included also seismic loads and conservative disc pressure loads.

The probability of the seismic and LOCA event occurring at the same instant the purge valves were opened for containment inerting or inservice testing would be very low.

The worst case torque coefficient (CT(0)=CT(90*),

5.0 CONCLUSION

S

(--)

The evaluation shows that the differential pressure capability of the 10 inch and 24 inch drywell purge valves are not exceeded during a DBA.

Therefore, the Technical Specification maximum allowable closure limit is adequate to ensure valve operability, and no further limitations beyond the reouirements of ASME Section XI, Article IWV-3417 need be imposed for measuring closure times during inservice testing.
