Enclosure 1 The Nuclear Regulatory Commission (NRC) Staff has requested the following additional information to support review and approval of Reference 1.

NRC Question 1:

1. In response to the staffs request for additional information, PINGP provided a portion of the EDG loading calculation, ENG-EE-021. On page 8 of the calculation, Section 2.3 states that the intermittent loads had their kilowatt loading reduced to 50% per assumption 4.2.f. Provide the worst-case loading profile, magnitude and duration, for the EDGs assuming 100% capacity of the intermittent loads at the onset of the event.

Provide bases for the assumption that intermittent loads are operating for 50% of the loading interval. Provide justification as to why the assumption that intermittent loads operating at 50% of the nominal rating is considered conservative from EDG loading perspective. If the profile places the predicted loading above the continuous rating of the EDGs, the amendment requested dated August 16, 2007 would be affected since NRC Regulatory Guide (RG) 1.9, Revision 4 assumes that the worst-case design basis loading is within the continuous rating with 5 percent margin. In addition, RG 1.9, Revision 4, Section C, Position 2.2.4, "Rated Load Test," which also applies to the monthly EDG test, states, "Clause 7.2.1.3(a) of IEEE Std 387-1995 should be supplemented as follows: If the design-bases event loads are higher than the continuous rating of the emergency diesel generator, the test should be conducted at the worst-case design-bases event loads." Therefore, if the peak loading exceeds the continuous rating of the EDGs, the proposed amendment request for the monthly test would not be consistent with RG 1.9, Revision 4, as stated in the August 16, 2007 amendment request.

Nuclear Management Company, LLC (NMC) response:

The Prairie Island Nuclear Generating Plant (PINGP) is not committed to Regulatory Guide (RG) 1.9, Revision 4. The Unit 1 emergency diesel generators (EDGs), D l and D2, are committed to Atomic Energy Commission General Design Criteria (GDC) 39, "Emergency Power for Engineered Safety Features," as proposed on July 10, 1967, which requires that alternate power systems will be provided and designed with adequate independency, redundancy, capacity, and testability to permit the functioning required of the engineered safety features. As a minimum, the onsite power system and an offsite power system will each, independently, provide this capacity assuming a failure of a single active component in each power system. The Unit 2 EDGs, D5 and D6, are committed to RG 1.9, Revision 2, except portions of the 1984 Edition of Institute of Electrical and Electronic Engineers (IEEE) Standard 387 were implemented in the factory testing instead of the 1977 revision. RG 1.9, Revision 4 was used in Reference 1 to compare the proposed TS against current regulatory guidance for EDG testing since the PINGP Unit 1 EDGs are not committed to any standard for testing.

The proposed test load is 90 - 100% of the continuous rating for the load run test as Page 1 of 6 stated in Section C, Regulatory Position 2, "Diesel Generator Testing", 2.2.3. The requirements of Section C, Regulatory Position 1, "Design Considerations", 1.3 appears to apply to diesel generator sizing considerations during the operating or combined license stages of review.

An evaluation of NMC engineering calculation ENG-EE-021, "Diesel Generator Steady State Loading for an SI [Safety Injection] Event Concurrent with Loss of Offsite Power (LOOP) for D l , D2, D5, D6", for the 0-5 minute period assuming 100% loading of the intermittent loads is provided as Enclosure 2 to this letter. The 0-5 minute period was chosen as "the onset of the event and bounds the event loads which do not change significantly over the first hour of the event. This evaluation also includes increased loading due to line and transformer losses. As discussed below, the SI event with a LOOP is the worst case loading for a design basis event at PlNGP on the EDGs. A summary of the loading, assuming 100% capacity of the intermittent loads, is 2491.86 kW for D l , 2636.99 kW for D2, 3864.53 kW for D5 and 3467.30 kW for D6 which is below the continuous rating of each EDG. The margin to the continuous duty rating for each EDG is 258.14 kW for D l , 113.01 kW for D2, 1535.47 kW for D5 and 1932.70 kW for D6. (Note these values are from an evaluation performed using Revision 3 to ENG-EE-021 and will not match values stated elsewhere. USAR updates will be prepared based on the latest revision to ENG-EE-021 in accordance with PlNGP program requirements.)

Loads categorized as intermittent loads are those that may be powered by buses connected to the EDGs following load sequencing, but are not assumed in accident analyses or are not likely to be operating the whole duration of the event. Since these loads may or may not be operating at any given time during the event, the intermittent loads were assumed to contribute a load to each EDG equivalent to 50% of their nominal rating.

The assumption that these loads operate at 50% during the event is conservative as demonstrated in the following discussion. The largest loads included in the intermittent category are the Group B pressurizer heaters which account for 192 kW on each EDG, or 96 kW with 50% loading assumed. The pressurizer heaters are not credited in the accident analyses. In the event of a large break loss of coolant accident (LOCA) with a LOOP, these heaters will trip on pressurizer low level before the pressurizer heaters are re-energized from the EDGs at load sequencer Step 6 (t=25 seconds) which is approximately 35 seconds after the diesel start signal. Since the pressurizer is located at a high point in the reactor coolant system (RCS), water from the various emergency core cooling system (ECCS) pumps will flow out of the break rather than refilling the pressurizer. Therefore, throughout the injection and recirculation phases of the accident, the pressurizer heaters will not be energized.

The 50% intermittent loading assumption places 96 kW on each EDG, although no Group B pressurizer heater load would be anticipated; the 100% intermittent loading assumption used in Enclosure 2 places an additional 96 kW, for a total of 192 kW, on each EDG. D2 is the highest loaded Unit 1 EDG and the diesel with the least margin to Page 2 of 6 its continuous rating. The D2 loading, assuming 100% loading of the intermittent loads minus the Group B pressurizer heaters, would be 2445 kW which is below the D2 loading in calculation ENG-EE-021, 2459 kW, which assumed all intermittent loads at 50%. As this evaluation demonstrates, since these heaters do not operate during a large break LOCA, the 50% intermittent load assumption is conservative.

The design basis loads, LOOPILOCA, are within the continuous rating of each EDG even if the intermittent loads are assumed to operate 100% of the time during the onset of the event. Reduction of the intermittent loads by 50% is a conservative assumption used in the design basis calculation for the EDG loading. Thus NMC concludes that the loads for the Unit 1 EDGs proposed in Reference 2, are the appropriate test loads.

NRC Question 2a:

Calculation ENG-EE-021 stated that the bounding case for diesel steady state loading is defined to be a large break (LB) LOCA in conjunction with a LOOP (Input 5.2, page 13).

Calculation ENG-EE-021, page 94, indicates that the 0-5 minute loading on D2 is 2538.57 kW. Revision 29 of the USAR states that the peak LOOPILOCA load is 2453 kW, and the maximum steady state loading during this event is 2479 kW. The USAR also states that the maximum predicted peak load for either U1 EDG during a U2 SBO event is 2624 kW.

a. Provide justification that the LBLOCNLOOP is the bounding case (i.e., worst-case loading) for EDG loading given that the USAR indicates that the peak SBO load is greater than the LBLOCNLOOP load. In addition, please indicate if the small break (SB) LOCNLOOP profile would ever place the loading above the continuous rating past the initial 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> of the event.

NMC response:

For PINGP, the worst-case loading is the large break LOCA with a LOOP. This is discussed in Chapter 8 of the USAR (page 8.4-7) which states:

Tables 8.4-1 and 8.4-2 show loading on Emergency Diesel Generators for a "worst case" condition as represented by a Safety lnjection signal coincident with a complete loss of offsite power. A "small break" LOCA that was sufficient to initiate automatic Safety lnjection (SI) action would represent the same inrush kVA load on the Emergency Diesel Generator as shown on the Tables cited. If the break is so small that automatic SI is not initiated, manual action would be required as soon as the operator is aware of the break. Manual action would represent loads less than or equal to that shown on the tables.

A small break would represent considerably less running load on the RHR

[residual heat removal] Pump and possibly less on the SI Pump, but a longer running time for the SI Pump. As shown in Table 8.4-1, this would represent Page 3 of 6 something less than 2453 kW shown as the maximum sequence load which is within the continuous rating of 2750 kW and 1000 hour0.0116 days <br />0.278 hours <br />0.00165 weeks <br />3.805e-4 months <br /> rating of 3000 kW for each Unit 1 Emergency Diesel Generator. Similarly, as shown on Table 8.4-2, this would represent something less than 3609 kW shown as the maximum sequence load which is within the continuous rating of 5400 kW for each Unit 2 Emergency Diesel Generator.

A small break LOCA would result in less loading from the SI pumps, due to less flow needed. The small break LOCA is defined as a rupture of the reactor coolant pressure boundary with a total cross-sectional area less than 1.0 ft2in which the normally operating charging system flow is not sufficient to sustain pressurizer level and pressure. A break of this size would not be expected to pressurize the containment to 23 psi thereby avoiding use of containment spray resulting in a reduction of 199.10 kW per EDG for each containment spray pump not used. This does not include the additional load of support equipment for these loads which also would not be energized.

While the station blackout (SBO) loading is larger for each EDG than the large break LOCA EDG loading, SBO is not a design basis event and the requirements for Alternate AC sources (AACs) for SBO coping are not the same as required for Class 1E emergency power sources.

Per the definition for Alternate AC sources (10 CFR 50.2), the AACs for PlNGP must have the capacity to support the analyzed SBO loading. For D l and D2 this means the loading could be supported up to 3250 kW for 30 minutes and up to 3000 kW for 1000 hours0.0116 days <br />0.278 hours <br />0.00165 weeks <br />3.805e-4 months <br />. Similarly for D5 and D6, loading could be supported up to 5940 kW for two hours out of any 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period and 5400 kW for 8760 hours0.101 days <br />2.433 hours <br />0.0145 weeks <br />0.00333 months <br />. This meets the requirements for SBO. NUMARC 87-00 also only requires the AAC be tested at rated capacity which NMC understands to be the manufacturer's ratings.

As stated earlier, D l and D2 are committed to GDC 39, "Emergency Power for Engineered Safety Features," as proposed July 10, 1967, which for PlNGP is interpreted to mean that D l and D2 analyzed loading should remain under the continuous duty rating of the EDGs for accidents in the safety analyses. D5 and D6 are committed to RG 1.9 Revision 2, which requires the conservatively estimated loads (nameplate) to remain below the continuous duty rating of the EDGs for accidents within PlNGP design bases.

The purpose of testing with the power factor is to demonstrate that the exciter can supply the necessary voltage and current to achieve the power factor and whether the generator can tolerate the increased heating due to the additional current for the apparent power. NMC chose the LOOPILOCA loads as the basis to determine the appropriate power factor for use in Surveillance Requirement (SR) 3.8.1.9, the EDG 24-month test. Although the LOOPILOCA loads may not be the highest analyzed loads that the EDGs experience, these loads represent the loads which the EDGs would supply for an extended operating period during a LOOPILOCA, that is, the EDGs are only required to provide SBO loads for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> versus the LOOPILOCA mission time of Page 4 of 6 336 hours0.00389 days <br />0.0933 hours <br />5.555556e-4 weeks <br />1.27848e-4 months <br />. Furthermore, the test loads in SR 3.8.1.9 are based on the EDG's continuous ratings which bound the LOOPILOCA and SBO loads. Thus NMC concludes that the LOOPILOCA loads are the appropriate loads from which the power factor determination should be made for use in SR 3.8.1.9.

The proposed SR 3.8.1.9 testing at 103 to 110% of the EDG continuous rating at a 0.85 power factor (if grid conditions permit) and the integrated SI test each refueling outage will demonstrate the capability of the exciter to supply the necessary excitation voltage and current.

NRC Question 2b:

Since the USAR EDG loading values differ from those in Table 1 on page 98 of the EDG loading calc, provide the worst-case peak kW values and durations of the values expected of the EDGs.

NMC response:

ENG-EE-021 Revision 3 provides the current evaluated worst case peak kW values and durations of the values expected of the EDGs. Page 101 of I 0 6 (not provided with the RAI responses in Reference 1) of ENG-EE-021 discuss the impact review for the calculation and, as a result of the updated analysis, an action was issued to update the Updated Safety Analysis Report (USAR).

Question 3:

Clarify the 2-hour rating for EDGs D5lD6 stated in Acceptance Criterion 3.2 of the calculation (page 9). Specifically, verify if this is the manufacturer-specified 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> rating (i.e., the load at which the EDG can operate for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> and is usually equivalent to 1 year of continuous operation at the continuous rating), or the short-time rating as defined in IEEE 387. Some manufacturers state that if the EDG is operated at a rating for the entire duration of that rating (i.e., if the EDG is ran for 30 minutes at the 30-minute rating kW value, or for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at the 2-hour rating kW value), the EDG operation cannot be guaranteed afterward (the EDG requires a tear-down inspection and maintenance). Note that the NRC staff does not consider the 2-hour rating the same as the short-time rating defined in IEEE 387."

NMC response:

The requirement to not exceed 5940 kW for a 2-hour period in calculation ENG-EE-021, Acceptance Criterion 3.2 is identical to the requirement of SR 3.8.1.9 which requires the Unit 2 EDGs to be tested at 2 5562 kW and 5 5940 kW for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />. Per SR 3.8.1.9, this 2-hour run is to be followed contiguously by a 22 hour2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> run.

Page 5 of 6 Chapter 8 of the USAR (page 8.8-6) states:

a. Load Capability Test The genset was started and run until system temperatures were at equilibrium.

The generator set was then loaded to 110% [5940 kW] of nameplate load for a continuous period of two hours. The generator set was then loaded to 100% of nameplate load (5400KW) for a continuous period of twenty two hours. Finally, the generator set was tested for loss of load transient response, which verified that engine overspeed values remained within acceptable parameters.

EDGs D5 and D6 were installed in the early 1990s as a modification to the plant. By letter dated September 29, 1989, and supplemented by letter dated December 15, 1989, the NRC was requested to evaluate the adequacy of the proposed qualification program dealing with the procurement and installation of these two EDGs. In a letter dated January 31, 1990, the NRC provided a Safety Evaluation for the EDG D5 and D6 Qualification Plan which stated:

The new EDG, rated at 5400kW continuous with a capability of 110 percent overload or 5940 kW for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> (in any 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period), 1200RPM, 4160V AC, and 0.8 power factor, will be manufactured by the French firm, Societe Alsacienne de Construction Mecaniques de Mulhouse (SACM). Each EDG set is a tandem unit using two SACM model UD45, 16 cylinder engines coupled with a single generator manufactured by Jeumont-Schneider of France.

Therefore D5 and D6 have been tested to have a 2 hour2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> rating of 5940 kW which has been reviewed and approved by the NRC. Operation at this rating followed by operation at the continuous rating is consistent with current TS testing requirements and the manufacturer's recommendations, that is, inspection and maintenance is not required following operation for 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> at 5940 kW.
