SEQUENCE OF EVENTS IN THE AUTOMATIC APPLICATION OF EMERGENCY AC LOADS ON LOCA(1)

AND LOOP EVENT TIME (sec)

Signal to start diesel 0 Diesel ready to load; start 10 one RHR pump motor Apply power to 440 V auxiliaries 13 and MOVs Start one core spray pump motor 17 Start one ESW pump motor 55 Control room chiller 177 Reactor building recirculation 193 fan (1)

This sequence applies to one diesel and its associated loads. The other diesels have a similar sequence and load.

SUMMARY

OF LOADING DIESEL GENERATOR AND EMERGENCY BUSES SAFEGUARD AND SELECTED NON-SAFEGUARD LOADS MAXIMUM LOADING OF ANY ONE DIESEL GENERATOR (kW)

TABLE 0 - 10 10 MIN - 1 HOUR and NO. DESCRIPTION MIN 1 HOUR LONGER 8.3 - 3 Assignment of safeguard and -- -- --

selected non-safeguard loads to diesel generators and emergency buses Both units in operation Unit 1 DBA; Unit 2 spurious LOCA 8.3 - 9 All D/G in service 2394 1910 1910 8.3 - 10 D11 D/G out-of -service 2397 2165 2165 8.3 - 11 D12 D/G out-of-service 2394 2222 2222 8.3 - 12 D13 D/G out-of-service 2394 1910 1910 8.3 - 13 D14 D/G out-of-service 2394 2190 2190 8.3 - 14 D21 D/G out-of-service 2394 2062 2062 8.3 - 15 D22 D/G out-of-service 2394 1846 1846 8.3 - 16 D23 D/G out-of-service 2394 2048 2048 8.3 - 17 D24 D/G out-of-service 2394 1824 1824 The above loadings are based on the minimum required engineered safeguard and selected non-safeguard laods for the following situation:

  • Unit 1 DBA with a spurious LOCA in Unit 2 for the 0 -10 minute period following by an emergency shutdown of Unit 2.

CHAPTER 08 8.3-54 REV. 15 SEPTEMBER 2010

LGS UFSAR TABLE 8.3-2 (Cont'd)

The case for a Unit 2 DBA is not tabulated. Due to the similarity in loading between Unit 1 and Unit 2, it has been determined that, for a Unit 2 DBA with a spurious LOCA and ESD in Unit 1, Unit 2 data on the following tables are conservative for Unit 1 and Unit 1 data are conservative for Unit 2.

All loads in the 0-10 minute period are automatically applied. Beyond 10 minutes, the major loads are manually connected or disconnected.

Nonsafeguard loads are tripped by the LOCA signal and may be manually added after the 0-10 minute period as permitted by the available capacity of the diesel generators (limited by fuel consumption) and as indicated in the table below.

The required minimum operation of ECCS pumps indicated is shown below:

DESIGN BASIS ACCIDENT EMERGENCY SHUTDOWN 0-10 10 min - Beyond 0-10 10 min - Beyond min 1 hr 1 hr min 1 hr 1 hr RHR pumps 3 1 1 0 1 1 CS pumps 2 2 2 0 0 0 RHRSW pumps 0 1 1 0 1 1 Any combination of three-out-of-four divisions (EDGs) is acceptable for a single failure. However, the ECCS requirements (as stated in paragraph 6.3.1.1.2), an EDG operable configuration of two-out-of-four is also acceptable.

There is more than one instrument in the control room to monitor this parameter and these instruments are not fed from the same bus; therefore, the loss of one bus will not affect the operator's ability to determine the value of this parameter.

B. This parameter can be determined from other parameters or local instruments if needed. Loss of this parameter would not affect the capability of achieving a cold shutdown condition.

C. The RPIS receives data from the RMCS and is fed from non-Class 1E instrument buses. If power to these buses is lost, rod position indication will be lost in the control room. Loss of rod position indication does not prohibit a manual or automatic SCRAM; therefore, the capability to achieve a cold shutdown condition is not affected by loss of power to the RMCS or the RPIS.

D. Loss of this parameter does not affect the ability to achieve a cold shutdown condition.

E. The SLCS has been redesigned per ATWS requirements. The controls and instrumentation of this system have been designed to perform their function with a single failure; therefore, loss of power to a single division will not prevent the achievement of a cold shutdown condition.

CHAPTER 08 8.3-114 REV. 13, SEPTEMBER 2006

LGS UFSAR Table 8.3-30 (Cont'd)

F. CST level indication will be lost when Y106 is lost; however, the tank HI/LOW level alarm will still be operable.

G. If power from panel BD102 is lost, the HPCI becomes inoperative. If this occurs, the ADS will be used to depressurize the reactor vessel so that the RCIC and RHR and core spray systems can be used to achieve a cold shutdown condition. Loss of HPCI due to loss of panel BD102 will not affect the ability to achieve a cold shutdown condition.

H. If power from panel AD102 is lost, the RCIC system becomes inoperative. If this occurs, the HPCI system can be used in its place; therefore, the loss of the RCIC system due to the loss of power from panel AD102 will not affect the ability to achieve a cold shutdown condition.

K. Core spray system instrumentation for Loop A is fed from Division 1 Class 1E power. Loop B instrumentation is fed from Division II. Loss of panel Y101 will cause loss of Loop A flow indication in the control room. Loss of Y102 will cause loss of Loop B flow indication. Loss of either of these panels does not affect the operability of the core spray system; therefore, the ability to achieve a cold shutdown condition is not affected.

L. Both of the supply panels must be lost in order to lose indication of this parameter.

M. The RHR system is composed of two redundant loops, each consisting of two pumps and one RHR heat exchanger. The pressure controllers, flow indicators, and pressure indicators for the A loop are fed from separate power panels than those for the B loop. The loss of one bus feeding RHR instrumentation would not affect the operating capability of the RHR system and therefore, would not affect the ability to achieve a cold shutdown.

N. This system has redundant loops. The instrumentation on each loop is fed from separate buses; therefore, the loss of one loop or panel will not affect the ability to achieve a cold shutdown condition with the remaining loop.

O. There is more than one instrument in the control room to monitor this parameter and these instruments are fed by two buses (redundant power); Therefore, the loss of one bus will not affect the operators ability to determine the value of this parameter.
