Re: Loss of SW SDP Hi Tom - just a few thoughts from a team meeting we had today.

1) We would like to know the basis for the operator failure rates quoted in the previous e-mail.

2) We are unable to find a procedure that directs the use of the city water to SAFW following a LOSW if the CST is not depleted. (i.e.,no step in ATT-5.1 to verify the avavability of the SW

, suction source or lineup city water)

3) The loss of IA procedure does cross tie to SA - so feed and bleed appear to apply.

4) Is there a cross tie from city water to the firemain in the IB, if so what directs its use?

FYI, here is a little more info from Mark. Both of us will be unavailable on Monday, and Mark will also be gone Wed. through Friday. Tuesday is good for both of us.

Loss of SW SDP Since I will only be in the office on Tues next week, I performed an additional review of the SDP as sent by the NRC on 12/29/00 related to the loss of SW procedure issue identified in the NRC inspection. Based on this, I would like to offer the following:

Event Tree 10 (LSSW) is missing all feed and bleed (F&B) functions.

This apparently was done on the premise that F&B requires SI, PORVs, and all supporting functions. SI has no SW dependencies as described in the PSA Final Report (Section 6.17.4.d) and the Ginna UFSAR (Section 6.3.2.2.2.1). At the time the event trees were being developed, there was some question about whether the PORVs, on nitrogen only, was sufficient for F&B. RG&E agreed that it was not and the PSA now requires IA in addition to nitrogen for F&B purposes. Table 2 of the 12/29/00 SDP identifies through Note 8 that the Service Air compressor is air cooled and does not require SW. Therefore, F&B should be

considered for the LSSW event tree (and for the for loss of CCW tree).

I would imagine this would would have a large effect on the results.

The SDP Worksheet for loss of SW (Table 3.12) identifies a failure rate of 0.1 for the operators to align city water to the SAFW system and to provide fire water to the TDAFW lube oil cooler. The PSA currently uses 1.OOE-02 and 6.70E-03 for these events, respectively (or at least one order of magnitude lower). However, the following things should be pointed out:

If all SW is lost, then fire water to the TDAFW pump is likely lost since they take suction from a similar location. City water to SAFW would remain available since this is a different source. The PSA reflects this by the fact that event SWCXXSUCTN, TOTAL FAILURE OF COMMON SW/FIRE WATER SUCTION fails both SW and the fire water pumps.

This event forms the basis for most of the frequency of losing all SW as an initiator (versus the random failure of 4 SW pumps).

The PSA operator failure rates are based on losing all AFW at the start of the transient. If the TDAFW pump runs for 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months before failing, there is a lot of additional time before SG tube uncovery that would lead to a more likely operator success.

I hope these help.

Re: Loss of SW SDP

1) I'm e-mailing the info that Mark provided, any detailed discussion of this should probably wait until next week.

2) The lineup is controlled by ER-AFW.1, which is entered from about a bazzilion EOPs. I'll assume that you still have a copy of this. The procedure is intended to give the Operators many options in getting water into the steam generators. To some degree you need to rely on RO/SRO training.

3) no response requested.

4) I attached procedure SC-3.16.4.1 (it's in WordPerfect). This procedure is utilized by Operations anytime there is major maintenance of the fire system (like today!).

Re: Loss of SW SDP Hi Tom - hope you had a good weekend.

Thanks for the last info.

We would like to gather the necessary furhter information this week, so that we can have a call with you, if necessary on Thursday or Friday. Please see the attached questions ( some of the answers overlap, but it was the easist way to make sure the bases were covered)..

I'll be out on Tuesday but in the rest of the week.

Thanks fcor your help.

SDP Questions Ginna SSDI

1.

Does the Ginna PRA assume the need for the crosstie of the cooling water from the fire main for total loss of service water scenarios? If so, was the assumption of the frequency of success the same as assumed in AFHDALTTD? If so, this does not appear appropriate since the operator must recognize (proceduralized) the loss of fire water and take actions to align the city water to the fire headers (proceduralized) and also recognize (not proceduralized) the need to connect the temporary supply hose (proceduralized).

2.

How would you estimate the Diagnosis HEP for the LOSW event, (given no procedure guiding the operator recognition) verse time for:

1.

The alignment of City/Fire water to the TDAFW pump of the need to complete Att 5.2?

2.

The alignment of City Water to SAFW?

3.

Was the Total mean HEP for the City water to fire water ever calculated? Has it been calculated now? If so what is it? (Please include the calculation).

4.

Relative to crediting feed and bleed for a LOSW - What does the current PRA assume?

We think that the SDP assumes no feed and bleed because the recirc capability would not be available. Does the PRA assume anything relative to the time dependance until the RWST reaches the point for swapover? Are there procedures in place for establishing a source of cooling water to the RHR Hxs, without SW?

5.

What is the current PRA core damage prob for LOSW? What would the LOSW core damage probability be given: (for each please include the sequences of interest and the assumed failure probabilities. If feed and bleed is credited please explain how.

1.

Inability to align Firewater to the TDAFW pump (given nominal failure probability for aligning city water to SAFW).

2.

Inability to align Firewater to the TDAFW pump and inability to align city water to SAFW.

NRC Questions Here they are:

(See attached file: RiskQuestions.wpd)(See attached file: LOSW2.xls)(See attached file: LOSWI.xls)

SDP Questions Ginna SSDI In order to ensure that everyone is talking from the same page, here is a summary of the expected loss of service water (LOSW) scenario that will be used as a reference point in responding to the NRC questions.

A.

Given a LOSW, the plant would trip either automatically or manually within a few minutes due to loss of BOP related equipment, CCW to the RCPs, etc. The following equipment (as a minimum) will be assumed failed due to the loss of SW:

IA Compressors A, B, C. However, the service air compressor (normally cross tied to IA) and the diesel air compressor are available.

MDAFW Pumps A and B. However, the TDAFW pump will auto start on low SG level (shrink due to reactor trip) and the SAFW pumps will be available.

CCW high temperature alarms will result in tripping the CCW pumps. This will fail cooling to the RCPs (which will also be tripped) and the RHR heat exchangers (failing sump recirculation and RHR cooldown).

MFW pumps B.

Once the plant has tripped, the operators enter procedure E-0. It would be expected that SI conditions would not exist (nor a manual SI required) and operators would exit E-0 after step 4 and enter procedure ES-0.1.

C.

Upon exiting E-0, the STA would consult the Critical Safety Function Status Trees (CSFSTs) per EOP usage guides (procedure A-503.1) and the note prior to the first step in ES-0.1. Included within the CSFSTs is verification that there is 200 gpm total AFW flow and 5% level in at least one SG. The STA performs this verification approximately once every 10-20 minutes (step 3.2.10.3 of procedure A-503.1). At this point, there is also a shift briefing to discuss the plant status. It would be expected that the loss of SW would be discussed, but we will assume that this is not discussed for the purpose of this review.

D.

Procedure ES-0.1 provides instructions to the operators to stabilize the plant and bring it to hot shutdown conditions. There is a step to verify the number of operating SW pumps

(#5) and a continuous action step (#9) to verify SG level > 5%. The last step of the procedure requires the operators to consult plant staff to determine if cooldown is required and to go to procedure ES-0.2 for natural circulation cooldown (since there are no RCPs). It can be assumed that between the plant staff and licensed operators, that a decision would be made to limit the plant cooldown with no SW present since CCW and RHR are not available. However, it will be assumed that the 2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months run time with no SW lube oil cooling to the TDAFW pump will not be identified since this is only found in procedure ECA-0.0 (SBO).

E.

Procedure ES-0.2 instructs the operators to cooldown and depressurize the RCS using natural circulation. As mentioned above in D, it can be assumed that the plant cooldown would be limited with no SW available. However, it will now be assumed that the TDAFW pump fails after 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months of operation with no SW cooling for lube oil. Since AFW and maintaining SG level is a basis for providing natural circulation, it would be expected that operators would be monitoring it closely. The STA would also be monitoring these as part of the CSFSTs once every 10-20 minutes. Between these and the expected control board alarms, operators would transition to FR-H.1 upon loss of the TDAFW pump.

F.

Procedure FR-H.1 instructs the operators to restore feedwater flow to the SGs first by preferred AFW, then by MFW, then by SAFW. Preferred AFW and MFW will be

assumed unavailable such that only SAFW can be used. EOP Attachment 5.1 instructs the operators to align SAFW taking suction from SW. Procedure ER-AFW.1 provides instructions on how to use alternate suction sources (e.g., city and fire water); however, there is no direct links to ER-AFW.1 from FR-H.1 and Attachment 5.1 other than CST level < 5 feet. Regardless, the operators know that SW is unavailable and have been trained on the use for ER-AFW.1 for similar type circumstances. That is, ER-AFW.1 is considered to be an Abnormal Operating Procedure (AOP) that is referenced by the EOP series of procedures. Operators are trained and expected to utilize AOP type of procedures as needed in support of EOP implementation. Also, the minimum CST level specified in LCO 3.7.6 is based on providing sufficient inventory for the TDAFW pump for 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months post trip in accordance with NUREG-0737, item II.E.1.1. As such, the operators would be expected to be procedurally directed into ER-AFW.1 from low CST level at about the same time that the TDAFW pump would fail due to insufficient lube oil cooling.

G.

If AFW, M FW, and SAFW cannot be implemented by FR-H.1, then the operators are instructed to use the condensate system or implement feed and bleed. The condensate system has no dependancies on SW, but does require depressurizing the SGs which could be accomplished using ARVs especially given 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months of successful TDAFW operation. Feed and bleed occurs until necessary subcooling margin is obtained such that the SI pumps can be stopped and the PORVs closed. At this time, the plant would go to normal RHR shutdown cooling (requires SW), sump recirculation (requires SW), or stabilize on AFW that has been restored. Assuming a SI flowrate of 500 gpm (each pump is designed for 350 gpm and given the initial lower decay heat levels) and 300,000 gallons of RWST inventory, the need to be on RHR or AFW would not occur before 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months . It can be expected that either SW, the TDAFW pump, or SAFW would be recovered within this time frame. However, the PSA model assumes that recirculation capability is required (i.e., there is no credit for this recovery).

1.

Does the Ginna PRA assume the need for the crosstie of the cooling water from the fire main for total loss of service water scenarios? If so, was the assumption of the frequency of success the same as assumed in AFHDALTTD? If so, this does not appear appropriate since the operator must recognize (proceduralized) the loss of fire water and take actions to align the city water to the fire headers (proceduralized) and also recognize (not proceduralized) the need to connect the temporary supply hose (proceduralized).

As indicated in PSA Final Report, Appendix F, Table F-4, event AFHFDALTTD is only credited for SBO scenarios (i.e., scenarios where procedure ECA-0.0 is entered). All other scenarios use a value of 1.0 for using fire water to support the TDAFW pump.

2.

How would you estimate the Diagnosis HEP for the LOSW event, (given no procedure guiding the operator recognition) verse time for:

a.

The alignment of City/Fire water to the TDAFW pump of the need to complete Att-5.2?

b.

The alignment of City Water to SAFW?

The diagnosis for alignment of fire water to the TDAFW pump (AFHFDALTTD) and city water to SAFW (AXHFDCITYW) was based on the following:

a.

AFHFDALTTD - Cues to perform this action would only be available upon entering ECA-0.0, Step 8.d. All other scenarios do not credit this action (i.e.,

failure probability of 1.0).

b.

AXHFDCITYW - Cues to perform this action would be from one of the following:

(1) low CST level - found on foldout page of all EOPs, (2) Step 13.a RNO of Procedure FR-C.1 for inadequate core cooling if SG level cannot be maintained >

5%, (3) Step 7 of Procedure FR-H.1 for inadequate heat sink if SAFW cannot be aligned to SW. Note that for the last item, there is no direct procedural guidance.

However, as described in item F of the event summary, operators are expected to utilize AOPs like ER-AFW. I in a situation like this. The calculation of this value was previously provided to the NRC and assumes that the operator had 20 minutes of diagnosis available. With 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months of successful TDAFW operation, this diagnosis time would be much longer.

Was the Total mean HEP for the City water to fire water ever calculated? Has it been calculated now? If so what is it? (Please include the calculation).

No HEP for this event has ever been calculated, nor is there any intention of generating one at this time. Instructions to perform this step are not contained within the EOP and AOP series of procedures (i.e., they are in other plant testing procedures). However, this activity is performed during testing and maintenance of the fire water systems and is called out in the TRM for when both fire pumps are inoperable (i.e., establish a backup fire water system). That is, operators are aware of this capability.

4.

Relative to crediting feed and bleed for a LOSW - What does the current PRA assume? We think that the SDP assumes no feed and bleed because the recirc capability would not be available. Does the PRA assume anything relative to the time dependance until the RWST reaches the point for swapover? Are there procedures in place for establishing a source of cooling water to the RHR Hxs, without SW?

The PSA utilizes a single transient event tree which contains, among other transients, the LOSW event (see PSA Final Report Figure 5-1). For the feed portion of feed and bleed, top event UH1 on the figure (High Pressure Injection) contains the logic for gate SR500, FAILURE TO DELIVER FLOW FROM 1 OF 3 SI PUMPS TO THE RCS DURING RECIRC. Since no recovery of SW is credited (as described in the event summary, item G), feed and bleed is not success for a LOSW event. However, since it would take over 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months to deplete the RWST, it could be postulated that the SW or AFW system would be recovered, or even the RWST refilled. There is no procedure which establishes an alternate source of cooling to the RHR HXs, primarily due to the number of AFW pumps.

5.

What is the current PRA core damage prob for LOSW? What would the LOSW core damage probability be given: (for each please include the sequences of interest and the assumed failure probabilities. If feed and bleed is credited please explain how.)

a.

Inability to align Firewater to the TDAFW pump (given nominal failure probability for aligning city water to SAFW).

b.

Inability to align Firewater to the TDAFW pump and inability to align city water to SAFW.

Three LOSW scenarios were solved as described below. In no instance is credit for feed and bleed taken.

LOSW as currently addressed within the PSA model - The attached cutset file (LOSW1.XLS) shows a of CDF 3.035E-06 with risk dominated by transients with no AFW available. Note that event AFHFDALTTD is only found in combination with a SBO event. Also, AXHFDCITYW is not found in the cutsets. This is due to the fact that there is already a human error event of failing to start SAFW per EOP steps (AXHFDSAFWX) within the models. For LOSW, this event also includes failure to align city water since no SW is available at the outset.

Consequently, event AXHFDSAFWX was increased by the necessary factor to result in a failure probability of 1.OE-02 similar to AFHFDALTTD.

LOSW with no credit for aligning Firewater to TDAFW-this is the same as the first sequence since event AFHFDALTTD is only credited for SBO cutsets.

LOSW with no credit for aligning Firewater to TDAFW nor city water to SAFW-If no credit is taken for TDAFW and the SAFW systems, then the CDF is equivalent to the LOSW frequency, or 2.OOE-04/yr (LOSW2.XLS). However, this scenario is not considered credible due to the reasons described above for the operators treatment of ER-AFW.1 as a AOP which is entered as necessary in the EOPs.

Also, if operators failed to align city water to SAFW in FR-H.1, they would go to feed and bleed. Once this failed due to lack of RWST inventory and ability to go onto RHR, the core would heat up and the operators would enter FR-C.1. This procedure has specific guidance to enter ER-AFW.1 in step 13.a RNO for when SG level is < 5% and 200 gpm of AFW cannot be established. Finally, the use of the condesate system has not been considered.

Loss of SW SDP Based on conversations with Jim Trapp on Wed, here is a revised letter:

SDP Questions Ginna SSDI In order to ensure that everyone is talking from the same page, here is a summary of the expected loss of service water (LOSW) scenario that will be used as a reference point in responding to the NRC questions.

A.

Given a LOSW, the plant would trip either automatically or manually within a few minutes due to loss of BOP related equipment, CCW to the RCPs' etc. The following equipment (as a minimum) will be assumed failed due to the loss of SW:

IA Compressors A, B, C. However, the service air compressor (normally cross tied to IA) and the diesel air compressor are available.

MDAFW Pumps A and B. However, the TDAFW pump will auto start on low SG level (shrink due to reactor trip) and the SAFW pumps will be available.

CCW high temperature alarms will result in tripping the CCW pumps. This will fail cooling to the RCPs (which will also be tripped) and the RHR heat exchangers (failing sump recirculation and RHR cooldown).

° MFW and Condensate pumps B.

Once the plant has tripped, the operators enter procedure E-0. It would be expected that SI conditions would not exist (nor a manual SI required) and operators would exit E-0 after step 4 and enter procedure ES-0.1.

C.

Upon exiting E-0, the STA would consult the Critical Safety Function Status Trees (CSFSTs) per EOP usage guides (procedure A-503. 1) and the note prior to the first step in ES-0.1. Included within the CSFSTs is verification that there is 200 gpm total AFW flow and 5% level in at least one SG. The STA performs this verification approximately once every 10-20 minutes (step 3.2.10.3 of procedure A-503.1). At this point, there is

- also a shift briefing to discuss-the plant status. It would be expected that the loss of SW would be discussed, but we will assume that this is not discussed for the purpose of this review.

D.

Procedure ES-0.1 provides instructions to the operators to stabilize the plant and bring it to hot shutdown conditions. There is a step to verify the number of operating SW pumps

(#5) and a continuous action step (#9) to verify SG level > 5%. The last step of the procedure requires the operators to consult plant staff to determine if cooldown is required and to go to procedure ES-0.2 for natural circulation cooldown (since there are no RCPs). It can be assumed that between the plant staff and licensed operators, that a decision would be made to limit the plant cooldown with no SW present since CCW and RHR are not available. However, it will be assumed that the 2 hour2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months run time with no SW lube oil cooling to the TDAFW pump will not be identified since this is only found in procedure ECA-0.0 (SBO).

E.

Procedure ES-0.2 instructs the operators to cooldown and depressurize the RCS using natural circulation. As mentioned above in D, it can be assumed that the plant cooldown would be limited with no SW available. However, it will now be assumed that the TDAFW pump fails after 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months of operation with no SW cooling for lube oil. Since AFW and maintaining SG level is a basis for providing natural circulation, it would be expected that operators would be monitoring it closely. The STA would also be monitoring these as part of the CSFSTs once every 10-20 minutes. Between these and the expected control board alarms, operators would transition to FR-H.1 upon loss of the TDAFW pump.

F.

Procedure FR-H. 1 instructs the operators to restore feedwater flow to the SGs first by preferred AFW, then by MFW, then by SAFW. Preferred AFW and MFW will be

assumed unavailable such that only SAFW can be used. EOP Attachment 5.1 instructs the operators to align SAFW taking suction from SW. Procedure ER-AFW. 1 provides instructions on how to use alternate suction sources (e.g., city and fire water); however, there is no direct links to ER-AFW.1 from FR-H.1 and Attachment 5.1 other than CST level < 5 feet. Regardless, the operators know that SW is unavailable and have been trained on the use for ER-AFW. 1 for similar type circumstances. That is, ER-AFW. 1 is considered to be an Abnormal Operating Procedure (AOP) that is referenced by the EOP series of procedures. Operators are trained and expected to utilize AOP type of procedures as needed in support of EOP implementation. Also, the minimum CST level specified in LCO 3.7.6 is based on providing sufficient inventory for the TDAFW pump for 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months post trip in accordance with NUREG-0737, item II.E.1.1. As such, the operators would be expected to be procedurally directed into ER-AFW. 1 from low CST level at about the same time that the TDAFW pump would fail due to insufficient lube oil cooling.
