RCS P/T Limits B 3.4.9 Brunswick Unit 2 B 3.4.9-8 Revision No. 87 BASES SURVEILLANCE SR 3.4.9.4 and SR 3.4.9.5 (continued) REQUIREMENTS Performing the Surveillance within 30 minutes before starting the idle recirculation pump provides adequate assurance that the limits will not be exceeded between the time of the Surveillance and the time of the idle pump start. | |||
An acceptable means of demonstrating compliance with the differential temperature requirement of SR 3.4.9.4 is to compare the temperature of the reactor coolant in the dome to the bottom head drain temperature. | |||
As specified in procedures, an acceptable means of demonstrating compliance with the temperature differential requirement in SR 3.4.9.5 is to compare the temperatures of the operating recirculation loop and the idle loop. | |||
SR 3.4.9.4 and SR 3.4.9.5 are modified by a Note that requires the Surveillance to be met only in MODES 1, 2, 3, and 4. In MODE 5, the overall stress on limiting components is lower. Therefore, T limits are not required. The Note also states the SR is only required to be met during recirculation pump startup, since this is when the stresses occur. | |||
SR 3.4.9.6, SR 3.4.9.7, and SR 3.4.9.8 Limits on the reactor vessel flange and head flange temperatures are generally bounded by the other P/T limits during system heatup and cooldown. However, operations approaching MODE 4 from MODE 5 and in MODE 4 with RCS temperature less than or equal to certain specified values require assurance that these temperatures meet the LCO limits. | |||
The flange temperatures must be verified to be above the limits 30 minutes before and while tensioning the vessel head bolting studs to ensure that once the head is tensioned the limits are satisfied. When in MODE 4 with RCS temperature 80F, 30 minute checks of the flange temperatures are required because of the reduced margin to the limits. | |||
When in MODE 4 with RCS temperature 100F, monitoring of the flange temperature is required every 12 hours to ensure the temperature is within the specified limits. | |||
SR 3.4.9.8 applies only to the reactor vessel flange and head flange temperatures; TS 3.4.9 does not limit the temperature of any other areas of the vessel when RCS temperature is 100F in MODE 4 or MODE 5, or when defueled. (continued) | |||
AC Sources-Operating B 3.8.1 Brunswick Unit 2 B 3.8.1-20 Revision No. 88 BASES SURVEILLANCE recommendations of Safety Guide 9 (Ref. 5), Regulatory Guide 1.9 REQUIREMENTS (Ref. 11), and Regulatory Guide 1.137 (Ref. 12), as addressed in the (continued) UFSAR. Where the SRs discussed herein specify voltage and frequency tolerances, the following summary is applicable. The minimum steady state output voltage of 3750 V is derived from the recommendations found in Safety Guide 9 (Ref. 5) and bounds the minimum steady state output voltage criteria of 3698 V associated with the 4.16 kV emergency buses analyzed in the AC Auxiliary Electrical Distribution System Study. This value (3698 V) allows for voltage drop to the terminals of 4000 V motors whose minimum operating voltage is specified as 3600 V. It also allows for voltage drops to motors and other equipment down through the 480 V level where minimum operating voltage is also usually specified as 90% of name plate rating. The specified maximum steady state output voltage of 4300 V ensures the maximum operating voltage at the safety related 480 V substations is no more than the maximum rated steady state voltage criteria for the 480 V motor control centers. The maximum steady state output voltage was determined taking into consideration the voltage drop between the DGs and the 4.16 kV emergency buses and a 5% voltage boost at the 480 V substation transformers. This maximum steady state output voltage also ensures that for a lightly loaded distribution system, the voltage at the terminals of 4000 V motors is no more than the maximum rated steady state operating voltage. The specified minimum and maximum frequencies of the DG are 58.8 Hz and 61.2 Hz, respectively. These values are equal to +/- 2% of the 60 Hz nominal frequency and are derived from the recommendations found in Safety Guide 9 (Ref. 5). | |||
SR 3.8.1.1 This SR ensures proper circuit continuity for the offsite AC electrical power supply to the onsite distribution network and availability of offsite AC electrical power. The breaker alignment verifies that each breaker is in its correct position to ensure that distribution buses and loads are connected to their preferred power source and that appropriate independence of offsite circuits is maintained. The 7 day Frequency is adequate since breaker position is not likely to change without the operator being aware of it and because its status is displayed in the control room. (continued) | |||

RCS P/T Limits B 3.4.9 Brunswick Unit 2 B 3.4.9-8 Revision No. 87 BASES SURVEILLANCE SR 3.4.9.4 and SR 3.4.9.5 (continued) REQUIREMENTS Performing the Surveillance within 30 minutes before starting the idle recirculation pump provides adequate assurance that the limits will not be exceeded between the time of the Surveillance and the time of the idle pump start.
An acceptable means of demonstrating compliance with the differential temperature requirement of SR 3.4.9.4 is to compare the temperature of the reactor coolant in the dome to the bottom head drain temperature.
As specified in procedures, an acceptable means of demonstrating compliance with the temperature differential requirement in SR 3.4.9.5 is to compare the temperatures of the operating recirculation loop and the idle loop.
SR 3.4.9.4 and SR 3.4.9.5 are modified by a Note that requires the Surveillance to be met only in MODES 1, 2, 3, and 4. In MODE 5, the overall stress on limiting components is lower. Therefore, T limits are not required. The Note also states the SR is only required to be met during recirculation pump startup, since this is when the stresses occur.
SR 3.4.9.6, SR 3.4.9.7, and SR 3.4.9.8 Limits on the reactor vessel flange and head flange temperatures are generally bounded by the other P/T limits during system heatup and cooldown. However, operations approaching MODE 4 from MODE 5 and in MODE 4 with RCS temperature less than or equal to certain specified values require assurance that these temperatures meet the LCO limits.
The flange temperatures must be verified to be above the limits 30 minutes before and while tensioning the vessel head bolting studs to ensure that once the head is tensioned the limits are satisfied. When in MODE 4 with RCS temperature 80F, 30 minute checks of the flange temperatures are required because of the reduced margin to the limits.
When in MODE 4 with RCS temperature 100F, monitoring of the flange temperature is required every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> to ensure the temperature is within the specified limits.
SR 3.4.9.8 applies only to the reactor vessel flange and head flange temperatures; TS 3.4.9 does not limit the temperature of any other areas of the vessel when RCS temperature is 100F in MODE 4 or MODE 5, or when defueled. (continued)
AC Sources-Operating B 3.8.1 Brunswick Unit 2 B 3.8.1-20 Revision No. 88 BASES SURVEILLANCE recommendations of Safety Guide 9 (Ref. 5), Regulatory Guide 1.9 REQUIREMENTS (Ref. 11), and Regulatory Guide 1.137 (Ref. 12), as addressed in the (continued) UFSAR. Where the SRs discussed herein specify voltage and frequency tolerances, the following summary is applicable. The minimum steady state output voltage of 3750 V is derived from the recommendations found in Safety Guide 9 (Ref. 5) and bounds the minimum steady state output voltage criteria of 3698 V associated with the 4.16 kV emergency buses analyzed in the AC Auxiliary Electrical Distribution System Study. This value (3698 V) allows for voltage drop to the terminals of 4000 V motors whose minimum operating voltage is specified as 3600 V. It also allows for voltage drops to motors and other equipment down through the 480 V level where minimum operating voltage is also usually specified as 90% of name plate rating. The specified maximum steady state output voltage of 4300 V ensures the maximum operating voltage at the safety related 480 V substations is no more than the maximum rated steady state voltage criteria for the 480 V motor control centers. The maximum steady state output voltage was determined taking into consideration the voltage drop between the DGs and the 4.16 kV emergency buses and a 5% voltage boost at the 480 V substation transformers. This maximum steady state output voltage also ensures that for a lightly loaded distribution system, the voltage at the terminals of 4000 V motors is no more than the maximum rated steady state operating voltage. The specified minimum and maximum frequencies of the DG are 58.8 Hz and 61.2 Hz, respectively. These values are equal to +/- 2% of the 60 Hz nominal frequency and are derived from the recommendations found in Safety Guide 9 (Ref. 5).
SR 3.8.1.1 This SR ensures proper circuit continuity for the offsite AC electrical power supply to the onsite distribution network and availability of offsite AC electrical power. The breaker alignment verifies that each breaker is in its correct position to ensure that distribution buses and loads are connected to their preferred power source and that appropriate independence of offsite circuits is maintained. The 7 day Frequency is adequate since breaker position is not likely to change without the operator being aware of it and because its status is displayed in the control room. (continued)
