2.0 CONCLUSION

S AND RECOMMENDATIONS The results o:)f the calculations indicate that the maximum continuous loading on either diesel generator occurs between 25 minutes and 30 minutes following SISLOP initiation, with 5152 KW load on Diesel Generator No.

1 and 5016 KW or Diesel Generator No.

2, as shown by Table 6.1.G. These maxima exceed the SONGS 1 Technical Specifications load limit of 4725 KW (4500 +5%).

It is therefore recommended to (a) raise the Technical Specifications load limit and/or (b) re-evaluate load requirements for possible reduction of the generator loadin v to.within the Technical Specifications load limit KW thru administrative controls and/or physical modifications.

3.0 METHODOLOGY AND ASSUMPTIONS The continuous load KW calculations were performed as described in the following sub-sections.

The list of safety Loads required following SISLOP were obtained from the Load Sequencer Schedule Drawings (Reference 5.3) and input from Nuclear and Mechanical Engineering.

These loads consist of several load groups which are started automatically by the Sequencer as well as by system conditions,and loads that are administratively controlled.

It should be noted that 480V Switchgear No.

is transferred to 4160V Switchgear No.

2 (Train 2) following SISLOP.

3.2 Individual Load Calculations The load characteristics were obtained from SONGS Station Equipment Data manual (Reference 5.1) and Design Calculation DC-1857 Rev 1 (Reference5.7).

As shown by Tables 6.1.A through 6.1.H, the motor continuous load kilowatts (KW) were calculated by using the following methodology:

KW

=

0.746 x BHP /EFF input where :

BHP is the brakehorsepower provided by Mechanical Design Calculation (Reference 5.1) for 4160V and 480V switchgear motor loads. For 480V MCC motor loads, BHP is assumed 75%

of motor rated HP as shown on Design Calculation DC-1857 Rev. 1.

EFF (Efficiency) and PF (Power Factor) are the rated full load values for the 4160V and 480V motors operating above or close to their rated HP and obtained from motor data sheets in the Equipment Data Manual (Reference 5.6) or, when not available, from Westinghouse typical medium.

voltage motor characteristics (Reference 5-8).

NoMA09 §VCATE____________AT For MCC motors, typical values of EFF and PF were used for motors operating at 75% of rated HP (extracolated from Design Calculation DC-1857, pages 25 and 86).

The static load KWs as well as the data used to calculate transformer and cable KW losses were extrapolated from the one-line diagrams and Design Calculations DC-1809 Rev.

1 and DC-1931, Rev.

O. The data used in the calculation for the KW input to MOV-850C UPS was extrapolated from Design Calculation DC-943 Rev.1 (Reference -5.12).

3.3 EAreGEOiY Diee Generator Lading Calculations The sum of the individual loads of each safety load grou (i.e., SUM A and SUM B) were used to obtain the operating load totals for the subsequent loadingtime intervals (SUM C and SUM D),

as shown on Tables 6.1.A thru 6.1.H.

The sum of the peak operating load aid the corresponding transformer and cable losses represent the highest continous loading on the diesel generator.

Upon SISLOP initiation, the following are assumed:

A. As a conservative approach, the Auxiliary Feedwater pump is actuated after 40 seconds.

B. The Waste Sump pump operates after 10 minutes (based on relay time delay setting).

C. The Recirculating pump and associated MOVs are manually activated after 25 minutes, during transition phase from injection to recirculation.

D. The Safety Injection pump, the Feedwater pump and the Feedwater pump lube oil cooling fan operations are secured after 30 minutes.

E. The Emergency Siren and the Thunderbolt evacuation system are turned off.after 30 min.

F.

The controls for the diesel generator starting air system auxiliaries are placed in the non-auto mode after 30 minutes.

G. Motor operated valve (MOV) stroke time is between 9 and 11 seconds.

H. As a conservative aporoach, all other intermittent loads operate continuously.

Prior to start of the calculation, it was necessary to determine and identify all the loads that could turn on and draw power from the diesel generators. The following documents and their associated one-line diagrams and elementary diaagrams were reviewed and used to derive the groups of loads in accordance with their sequence of oD'perat ion.

The brake horsepower requirements of the feedwater, safety injection,

charging, auxiliary feedwater, and component cooling pumps were obtained from Design Calculation DC-2990, Rev.

ENCLOSURE 2 re ENGINEERING AND SCIENTIFIC SERVICES na SIS 2225 EAST BAYSHORE ROAD. PO BOX 51470 a t PALO ALTO. CALIFORNIA 94303 (415) 856 9400 TELEX 704216 FaAA-PA-R-88-06-0 6 June 15, 1988 Mr. David Pilmer Southern California Edison Company P.O. Box 800 Rosemead, California 91770 RE:

Analysis of Piston Skirt Integrity J

17 1988 Delaval Diesel Engines San Onofre Nuclear Generating Station, Unit 1 U F. PILMER FaAA Project No.:

PA12842

Dear Mr. Pilmer:

This letter is in response to your letter of June 13, 1988 concerning the integrity of the modified AF piston skirts in service at San Onofre in the Delaval diesel engines.

As you are aware, Failure Analysis Associates performed an analysis of the modified AF piston skirts intended for use at the Shoreham Nuclear Power Station.

These engines were rated at a BMEP of 225 psig at 100% load, and our results concerning the integrity of the modified AF piston skirts was that "cracks will initiate and may propagate in the AF.

However, any cracks in the AF are predicted to arrest at depths less than 0.5 inch" (pg. iii of FaAA-84-5-18). These results are in accordance with the field observations of the modified AF Shoreham pistons.

These pistons were suitable for their intended purpose at Shoreham in that they did not impair the operability of the engines.

Subsequent to the analysis of the Shoreham pistons, I also performed a corresponding analysis of the San Onofre pistons taking into consideration the reduced BMEP rating of 154 psig (from the factory test log).

This reduction in the BMEP provides a reduction of the peak firing pressure. The peak firing pressure is the major contributor to stress in the piston skirt and is also available from the factory test logs of the engines.

The results of my analysis on the San Onofre engines were, to my knowledge, never transmitted in writing to either 'Southern California Edison or the TDI Owner's Group.

The results of my analysis were that cracks are likely to initiate in the piston skirt, and, under worst case conditions, the cracks could grow but would arrest at a depth of less than 0.45 inch.

This is somewhat less than the predicted arrested crack depth of the Shoreham piston skirts.

In your letter of June 13, you requested an analysis of the piston skirt integrity at 135 psig +/- 5%.

Since the 135 psig + 5% (= 142) BMEP is close to the value of 154 that I previously analyzed, the conclusion concerning the N DETROIT

Page 2 June 15, 1988 FaAA-PA-R-88-06-06 piston skirt integrity at 142 would be virtually the same as that at 154.

Consequently, the conclusions for the Shoreham (at 225 BMEP) and San Onofre engines (at 142 BMEP) are nearly the same, with the arrested crack depth for San Onofre being more favorable.

The above analysis, and conclusions drawn therefrom, consider the final state of the cracks in the piston skirts after a very large number of stress cycles.

If fewer cycles were placed on the piston skirts, then the depth of cracks present would be less than the final arrested depths mentioned above.

The depth of such cracks after a limited number of stress cycles following crack initiation could be calculated by fracture mechanics procedures.

The reduced size of cracks resulting from fewer cycles of operation would provide even more favorable crack depths.
