{{#Wiki_filter:NRC Resolution of Facility Post Exam Comments Facility Comment: Justifications for deleting Question 90 The SAFEGUARDS RELA YS DC POWER FAILURE alarm comes in. Investigation reveals that the DC Power Supply to the Train A Safeguards Rack has failed. No other alarms are up. Which of the following statements accurately describes the status of the Safeguards Initiation System to this event and what actions are required? A. SI Train A is disabled due to loss ofpower to the master relays. If SI is required, Train A equipment will start. Some Phase A valves will have to be manually aligned using E-O, Reactor Trip or Safety Injection Attachment 1 B. SI Train A is disabled due to loss ofpower to the master relays. If SI is required, Train A equipment cannot be started due to a loss of control power. Some Phase A valves will be properly aligned C. Automatic SI Train A is disabled due to loss ofpower to the master relays. If SI is required, Train A equipment will have to be manually startedlrealigned using E-O, Reactor Trip or Safety Injection Attachment 1. D. Automatic SI Train A is disabled due to loss ofpower to the master relay. If SI is required, Manual actuation of SI Train A is available and will actuate all safeguards equipment. Either train of Safety Injection will start most safeguards pumps (i.e., either train of Safety Injection will start all 3 SI pumps, both RHR pumps, etc.). However there is an exception The Auxiliary Component Cooling Water Pumps. The start signals for these pumps are train specific (i.e., Train A SI starts 21 ACCW Pump only and Train B SI starts 22 ACCW Pump only). In addition, some Non-Phase A valves receive Safety Injection signals to change position. Like the ACCW pumps these valve operations are Safety Injection Train Specific (i.e., RHR valve 746 is opened from a Train A Safety Injection signal only and RHR valve 747 is opened from a Train B Safety Injection signal only). See attached prints. If SI Train A is disabled and an SI is required, not ALL Train A equipment will start. As a result the originally identified correct answer, A, is not correct. This caused all three applicants to eliminate A as a possible answer. Recommendation: Delete Question 90 As an alternative, distracter C could be considered a correct answer. It is true that for the condition given Automatic SI for Train A is disabled; however, Manual actuation is also disabled. It is also true that some Train A equipment will have to be manually started/realigned

using E-O, Reactor Trip or Safety Injection Attachment I. The intent of this distracter was for the applicant to recognize that Manual Safety Injection for Train A is also disabled when the above condition occurs. This distracter, as an answer, is weak and not clearly correct. Alternative Recommendation: Correct Answer Key and accept C as the correct answer. Refer to drawings: A225016 Safeguards Acutation Schemes (Train A Only) Rev. 12 A225017 Safeguards Acutation Schematic Train "A" Rev. 23 A225018 Safeguards Acutation Schemes (Train 8 Only) Rev. 10 A225019 Safeguards Acutation Schemes (Train 8 Only) Rev 19 8225178 Elementary Wiring Diag. of Auxiliary Component Cooling Pumps #21 & 22 Rev 4 NRC Resolution: Facility comment accepted, question deleted. The facility submitted prints showing that the aux CCW pumps along with various ESF valves are train specific. As a result, the original correct answer which states that "Train A equipment will start" is not fully correct. The facility's proposed alternate answer, C, says "Train A equipment will have to be manually started / realigned...", and this is also not fully correct. Therefore the question is deleted as having no correct answer.

ENGINEERED SAFEGUARDS SYSTEM SD 10.0 REV 8 The Containment Ventilation Isolation signal will cause the following actions: Pressure relief line (valves PCV-1190, PSC-1191 and PCV-I192) will be signaled to close, and valves SOV-1279 and SOV-1280 will remain open to admit WCPPS air to fill the space between the FCV valves. Purge exhaust lines (valves FCV -1172 and FCV -1173) will be signaled to close, and valve SOY -128 will remain open to admit WCPPS air to fill the space between FCV's. The closing signal might be termed, for this case, as being redundant and only as assurance of a known condition. The pressure relief line can be open during operation to reduce containment pressure hence the signal is not redundant in this case. Having three valves in series provides assurance ofclosure ofthis relatively large line on demand. The remaining signals that will also result in containment ventilation isolation are:

1) Containment or exhaust stack Radioactivity (particulate and radiogas). This signal is not part ofthe safeguards system.
2) Manual or Auto Spray Actuation
3) Manual Purge Duct Trip switches on Panel SL in the Control Room 3.3.A.6 Control Room Ventilation Isolation The Sl signal swaps the Control Room Air Conditioner to the Incident mode. The air conditioner is also positioned in this manner by high radiation level on the control room radiation monitor. This latter signal is not considered part ofthe safeguards system. Refer to System Description 11 Ventilation Systems for further details on the Ventilation System.
  • II"~. ~gguence When the Safety Injection signal passes the Safeguards Sequence box on Figure 2 it accomplishes the following:

16

ENGINEERED SAFEGUARDS SYSTEM SD 10.0 REV 8 a) Commands all three diesel generators to start provided their controls are in automatic. The diesel start signal commands the service water by-pass gates to open. This assures flow to Service Water Pumps iftheir intake is blocked. b) It provides a signal to strip all loads off the 480 volt buses, except MCC 26A, 26B, 26C and 211. It opens the diesel generator output breaker, if any are closed, and locks out all non-safeguards loads by virtue ofnon-automatic breaker reclosure which have auto-start circuits*.

  • The component cooling pumps breakers will be prevented from closing if there is a blackout concurrent with Safety Injection After 3 second time delay this stripping signal is removed.

NOTE: MCC #24, #29, #211 are stripped only ifpower is lost to the respective 480V Bus sections. Essential loads: MCC#24 - Rod Indication Alt. Feed to Inst. Bus #22 MCC #29 Alt. Feed to computer Battery Charger #21 MCC #211 Motor operated upstream of feed water regulators c) It provides a signal to trip the tie breakers between all ofthe 480 volt bus sections. "'~des a signal to start the auxiliary component cooling pumps and positions various valves to line up injection paths into the core. e) After the three second delay signal and in the absence ofan undervoltage condition on respective 480 volt buses, the safety injection signal equipment sequence sends signals to the safeguards equipment on the four 480 volt buses. 17

ENGINEERED SAFEGUARDS SYSTEM SD 10.0 REV 8 If outside power has not been lost the 480 volt buses will be isolated and powered from their normal supplies and the diesels will run up to idle speed and normal voltage. If outside power has been lost, the normal bus feed breakers are tripped open and the diesels will be connected to the buses as follows: Diesel No. 21 to bus 5A 1 - If no diesel fault exists. 2 - Ifdiesel voltage is up to value. 3 - Ifbus 5A shows no fault. 4 - If loss ofoutside power is proved by under voltage relays on bus SA or 6A. 5 - Ifbus 5A shows undervoltage. Diesel No. 23 to bus 6A 1 - If no diesel fault exists. 2 - If diesel voltage is up to value. 3 - Ifbus 6A shows no fault. 4 - If loss ofoutside power is proved by under voltage relays on bus 5A or 6A. 5 - Ifbus 6A shows undervoitage. Diesel No. 22 to bus 2A 1 - If no diesel fault exists. 2 - Ifdiesel voltage is up to value. 3 - Ifbus 2A shows no fault. 4 - Ifloss of outside power is proved by under voltage relays on bus 5A or 6A. 5 - If bus 2A shows undervoltage. Diesel No. 22 to bus 3A 1 - If no diesel fault exists. 2 - Ifdiesel voltage is up to value. 3 - Ifbus 3A shows no fault. 18
