Executed on SEP 3 Mark A. Schimmel Site Vice President Prairie Island Nuclear Generating Plant, Units 1 and 2 Northern States Power Company - Minnesota Enclosures (1) cc: Administrator, Region Ill, USNRC Project Manager, PINGP, USNRC Resident Inspector, PINGP, USNRC State of Minnesota

Enclosure 1 Nuclear Regulatory Commission (NRC) request for additional information (RAI) 1.)

According to Surveillance Requirement (SR) 3.8.1.8.c of the Prairie Island Nuclear Generating Plant (PINGP) Technical Specifications (TS), the ground fault trip is not bypassed on an actual or simulated safety injection signal, in Unit Ionly.

Explain the difference between Unit 1 and Unit 2 regarding this trip and provide the basis for not bypassing the ground fault trip for Unit 1.

Northern States Power Company, a Minnesota corporation (NSPM) response:

The emergency diesel generators (EDGs) for the two Prairie Island Nuclear Generating Plant (PINGP) units were installed at different times and manufactured by different companies to different specifications. The Unit 1 EDGs (Dl and D2) were installed as original plant equipment to support both Units 1 and 2 which became operational in December 1973 and December 1974, respectively. The Unit 1 EDG design was compared with the guidance of Safety Guide 9, issued in March 1971, which discussed overspeed protection, but does not provide specific guidance for critical trips. The original design of the Unit 1 EDGs provided protection from significant electrical failures during a safety injection event which included generator differential and ground fault protection as detected by a diesel output circuit breaker. Specific test requirements for the bypass relay were first introduced in the PINGP TS by license amendments (LA) 25 and 19, for Units 1 and 2 respectively, issued January 18, 1978. The surveillance requirement in this LA required verification that the engine overspeed and generator differential current are automatically bypassed. Subsequently in LAs 49 and 43, for Units 1 and 2 respectively, dated July 28, 1981, the NRC issued a revision of the EDG trip test "to include a trip of the diesel generator on occurrence of a ground fault, as well as engine overspeed and generator differential current in the list of trips that are not automatically bypassed on receipt of a safety injection signal. The proposed change clarifies the TS to be consistent with the previously existing diesel generator design."

The Unit 2 EDGs (D5 and D6) were installed in the early 1990s in response to the station blackout rule and became operational in 1992. These EDGs were designed to meet the requirements of Regulatory Guide (RG) 1.9, Revision 2. The critical trips on Unit 2 EDGs (D5 and D6) are based on the guidance in RG 1.9, Revision 2 which discusses trips of the diesel generators based on overspeed conditions or a generator differential in order to protect the EDGs from damage or degradation.

NRC RAI 2.) Submit for the NRC staffs review, the applicable portions of representative procedures for performing SR 3.8.1.8 and relevant representative drawings showing the relays that provide the function to bypass the emergency diesel generator non-critical automatic trips on an actual or simulated safety injection signal. Also, discuss whether critical trips are tested as part of SR 3.8.1.8 or some other plant procedure.

Page 1 of 2

NSPM NSPM response:

The procedures for performing SR 3.8.1.8 are SP-1150 (Dl), SP-1306 (D2), SP-2150 (D5), and SP-2306 (D6). SP-1150 and SP-2306 are attached for review as a representative procedure for each unit. Additionally, as requested, representative logic drawings for each unit showing how the MCA (Maximum Credible Accident) and SlMR (Safety Injection Master Relay) relays operate, and bypass the non-critical trips during a safety injection signal, are attached.

The critical trips (engine overspeed, generator differential current, and ground fault (Unit 1 only)) are not tested as a part of surveillance procedures SP-1150, SP-1306, SP-2150, and SP-2306.

The proper operation of the components that perform these critical trips are tested during routine maintenance. The generator differential current and ground fault (Unit 1 only) trips are tested as a part of the relay calibration procedures for each EDG. The diesel generator relay calibration and functional testing procedures test the generator differential relays and the ground fault relays (Unit 1 only) to verify that each will properly actuate the respective diesel generator lockout relays. These relay calibration procedures are performed on a four year frequency. The proper operation of the overspeed trip function is verified during the routine diesel generator inspection procedures which are performed on a two year frequency.

5.0 SPECIAL CONSIDERATIONS 5.1 Load sequencer must be taken out of service for this inspection. The bus is placed in an analyzed condition per this WR for SI block loading prior to the load sequencer being placed in manual. This ensures the bus is in an operable condition.

5.2 All Train A required features supported by D5 Diesel Generator are required to be operable while in this test. any required Train A features become inoperable, THEN evaluation per 5AWI 3.15.8, Safety Function Determination Program, SHALL be performed.

5.3 T.S.3.3.4, 4kV Safeguards Bus Voltage Instrumentation, specifies the Required Actions that must be completed when removing the load sequencer from service.

5.4 Voltage is lost to Bus 26, THEN operator action is required to restore power to the Bus 26 per 2C20.5 AOP2.

5.5 Steps preparing to take Bus 26 Sequencer OOS and installation of a shutter barrier in cubicle 26-16 may be done prior to pre-job brief.

5.6 For steps noting a wire number, it is acceptable to verify the wire number is physically connected where specified by tracing jumperslwires internal to the associated panel. For example, IF an external wire is connected to terminal 1 terminal 1 is jumpered to terminal 10 AND terminal 10 is jumpered to terminal 15, THEN the external wire is considered to be connected to terminals 1, 10 and 15.
