RESPONSE TO REQUEST FOR ADDITIONAL INFORMATION ON THE SONGS 1 NUCLEAR INSTRUMENTATION SYSTEM UPGRADE
- 1. Provide a description of the proposed design change (i.e., the upgrade replacement of the NIS) as it relates to the DC and AC electric power systems.
RESPONSE
Presently, the NIS is supplied from four separate sources, Regulated Bus #1 (8-11R3), Regulated Bus #2 (8-12R3), Regulated Bus #3 (8-13R3), and Inverter #4 (via Fuse 8-14V3 located in the Regulated Bus #4 cabinet).
Inverter #4 (fed from DC Bus #1) supplies no other load.
Fuse 8-14V3 is normally supplied from Inverter #4 and alternately from Vital Bus #4. As part of the scope of the NIS upgrade work, existing Inverter #4 and Fuse 8-14V3 will be physically removed. Existing Inverter #4A which feeds Vital Bus #4 will be re-tagged Inverter #4. NIS Channel IV will be powered through Regulated Bus #4 similar to the other NIS Channels I, II, and III powered through Regulated Buses #1, #2, and #3.
The existing regulated Buses #1, #2, #3, and #4 are supplied from Vital Buses #1, #2, #3, and #4, respectively. The 120 V ac vital bus system is configured such that each vital bus can receive power from either of two redundant sources, via an automatic transfer switch. Normal power is supplied by a Train A source (125V DC Bus 1 thru an inverter), and alternate power is provided by a Train B source (MCC 2 thru a step-down transformer). No changes are being made to the regulated and vital bus power supplies.
The NIS upgrade work will install new AC power feeders from Regulated Buses #1, #2, #3, and #4 to the four-section NIS cabinet for NIS Channels I, II, III, and IV, respectively. These new feeders will be routed in accordance with current IEEE Std 384 and Regulatory Guide 1.75 physical separation requirements. This configuration improves the physical separation compared to the existing NIS.
- 2. In support of the replacement upgrade of the Nuclear Instrumentation System (NIS), as indicated by letter dated April 15, 1988, the upgrade of the NIS will increase the DC system load.
As a consequence of this increased load, the margin of safety for DC system capacity and capability will be reduced. The significant hazards consideration analysis (which states that the revision to the battery test acceptance criterion from 80 to 85 percent will ensure that an existing safety margin is maintained) does not adequately address reduced margin of safety for DC system capacity and capability due to increased load.
For each component part of the DC system (battery, charger, and distribution system components) that will be required to supply the increased load, provide the results of your analysis which demonstrates that the DC system can adequately accommodate the increased load.
-2
RESPONSE
The additional NIS loads (net) on Regulated Bus #1 (RB #1) (8-11R3), RB #2 (8-12R3), RB #3 (8-13R3), and RB #4 (8-14R3) are 3.8, 3.9, 0.37 and 5.46 amps, respectively. To accommodate these additional loads, the existing 5-amp fuses on 8-11R3, 8-12R3 and 8-14R3 will be replaced as part of the NIS design change with appropriately sized fuses. The 5-amp fuse on 8-13R3 is adequate for the additional loads; however, it is being replaced along with the other fuses.
The impact of these additional NIS loads on the rest of the Maintained 120V AC and 125V DC distribution system components, from the regulated buses up to and including the battery charger input breakers and the alternate supply breaker at MCC 2, was further evaluated for bus capacity, proper fuse/breaker sizing/coordination, component ratings, system voltages and short circuit capabilities. Each component has been found to be adequate to provide for the increased load requirements.
- 3. The significant hazards consideration analysis states that the battery specification revision (i.e., acceptance criteria for battery capacity revised from 80 to 85 percent) provides assurance that the system is tested in a manner consistent with its recalculated duty cycle. It is not clear how replacing a battery when its capacity reaches 85 percent assures a battery is capable of meeting its duty cycle. Provide the results of an analysis to indicate the extent to which recommendations of IEEE Standard 485-1983 have been followed in assuring adequately sized batteries at San Onofre Unit 1.
RESPONSE
Each section of the revised load duty cycle profile resulting from the additional NIS loads was analyzed to determine the adequacy of the existing battery, using the guidelines of IEEE Standard 485. Based on the IEEE Standard 450 recommendation that a battery be replaced when its actual capacity ages to 80 percent of its rated capacity, IEEE Standard 485specifies that the rated capacity should be initially sized to at least 125 percent of the required load to ensure that the battery at 80 percent capacity will still be capable of meeting this load duty cycle requirement.
The minimum required capacity was calculated to determine if the battery can accommodate the revised load duty cycle criterion. The available ampere-hour corresponding to 80 percent of the battery's 2550 ampere-hour rated capacity is 2040. The revised minimum required load capacity was calculated to be -2116 ampere-hours which corresponds to an 83 percent replacement criterion. Therefore, the revised load duty cycle requirement can still be adequately accommodated when the battery capacity is at the 83 percent value. The current capacity will be measured during the Cycle 10 refueling outage in accordance with an IEEE 450 performance test.
- 4. Section 4.2.5 of the Safety Review Report for the NIS indicates that each redundant channel set of the NIS is energized from a separate AC power source. This section, thus implies that there will be four physically and electrically separated AC sources supplying the NIS. Verify that this is
-3 so and provide a description of these power sources and their physical and electrical separation. If this is not the case, provide the results of an analysis which demonstrates that the existing electric power system design, which will supply the new NIS design, will not compromise the independence requirement for the NIS.
RESPONSE
It is noted that Section 4.2.5 is a discussion of the independence for the new NIS and not the NIS power supplies. The upgraded NIS receives four channels of independent AC power derived from existing Regulated Buses 1, 2, 3, and 4. Each regulated bus is separately fed from a vital bus source (Vital Buses 1, 2, 3, and 4), through a voltage regulator.
The 120V AC vital bus system is configured such that each vital bus can receive power from either of two redundant train sources of power, via an automatic transfer switch. Normal power is supplied by a Train A source (125V DC Bus 1 thru an inverter for each vital bus), and alternate power is provided by a Train B source (MCC 2 thru a step-down transformer).
Regulated Buses 1, 2, 3, and 4, are fed from Vital Buses 1, 2, 3, and 4, respectively, via feeders that share common raceways.
The vital bus power supplies were addressed as part of the Systematic Evaluation Program (SEP) review for Topic VI-7.C.2 Failure Mode Analysis (Emergency Core Cooling System). The NRC's review indicated that various recommendations were made by the licensee as part of a separation evaluation of the ECCS. Those recommendations included the physical separation of the vital buses, regulated buses, and associated cables.
SCE has committed to evaluate each of these recommendations and determine the need for a modification. The NRC staff considered this acceptable.
The resolution of the physical separation of the vital buses will be addressed as part of the resolution for the open items remaining from SEP and should not be included in the replacement of the NIS. The SEP evaluation was scheduled to be submitted by September 30, 1988. The submittal has been delayed to ensure the results of the single failure analysis and the environmental qualification work did not impact the results.
The vital bus power supplies were also addressed in the Reactor Protection System single failure analysis dated March 11, 1987.
The results of this review as they apply to the power supplies, are contained in Tables 4, 8-1, and 8-2. These tables are provided as an attachment to this response. The results indicate the reactor protection system functions of the existing NIS meet their design basis related to the single failure criterion, and therefore are electrically independent.

- a.
THIS SECTION EVALUATES FAILURES IN THE CHANNELIZED VITAL AND REGULATED BUS SYSTEM COMMON TO THE SCRAM FUNCTIONS.
IT WAS DEVELOPED IN PART USING THE SORT OF TABLES 1 -
7 FOR RACK POWER SUPPLY DEPENDENCY WHICH IS PROVIDED AS TABLE 8-2.
- b.
THE CREDIBLE FAILURE MODES FOR THE VITAL AND REGULATED BUS INVERTER AND TRANSFORMER SUPPLIES WERE CONSIDERED TO BE THOSE RESULTING IN BUS VOLTS LOW OR ZERO.
BUS VOLTS HIGH WAS NOT CONSIDERED CREDIBLE BECAUSE MULTIPLE FAILURES IN THE SAME CHANNEL (eg.
INVERTER AND REGULATOR) WOULD BE REQUIRED TO PRODUCE SUCH AN EFFECT AND SINGLE CHANNEL FAILURES WERE NOT LIMITING.
- c.
EXISTING BREAKER AND FUSE COORDINATION WERE CREDITED FOR PREVENTING THE PROPAGATION OF FAULTS INTO THE VITAL AND REGULATED POWER SUPPLY SYSTEM.
