Dear Sir:

Three. le Island Nuclear Station, Unit II (TMI-2) l Operating License No. DPR-73 Docket No. 50-320 BOP Equipment Electrical Power Supply As a result of the process of continued engineering review of the electrical power supply scheme to the TMI-II station, it has been determined that reroval of the BOP diesel-generators is justified. This justification has been submitted under cover of our letter dated March 4, 1980, TLL 078. This submittal identifies that the 115 kV intertie has been classified as an acceptable back-up source of power for necessary equipment for the removal of decay heat from the reactor in the present mode of core cooling. Further analysis has shown that the normal power supply to the auxiliary t rans f o rme rs, backed-up by " black start" combustion turbines, is equivalent, in terms of reliability and capacity, to the 115 kV power supply through the leased transformers. The attached Technical Evaluation Report (TER) documents the adequacy of the 230 kV power supply. Documented herein are: 1. The high reliability of the 230 kV pcwer supply. 2. The proposed routing of electrical energy from the combustion turbine power sources through the 230 kV transmission system. 3. The switching procedures to be used in the event of loss-of-off-site power (LOP) for the restoration of power. 4. The station procedure to be used in the unlikely event that LOP is experienced. kCol As a result of the information presented above and in the enclosed TER, it S f// is requested that the 230 kV power supply to the auxiliary transformers, in l 8004040 So't . m.. _. s _ m_ _.,_ ___,_., ,m. -.. - ...=.a._u..~__~-.-

  • Mnsformer. As indicated in our previous letter (TLL 078), the schedule for removal of the diesel-generators is early April, 1980.

TLL 150 BOP DIESEL GE::ERATOR AND 10 MVA TPa:;SFORMER REMOVAL I. INTRODUCTION Following the accident at TMI-II, secondary plant (BOP) equipment was utilized to provide the necessary core decay heat removal. To ensure the availability of power to this equipment in the event of loss of of fsite power, two 2500 KW diesel generators and a 10 MVA transformer was leased and installed as shown in Figure 1. The 10 WA transformer is used to provide power frca combustion turbines via the 115 KV grid and a 13.2 KV transmission line as shown in Figures 2 and 3. Since the combustion turbines have black start capability, this source was considered equivalent to an onsite power supply. BOP electrical loads necessary to support reactor decay heat removal are tabulated in Table 1. Among these electrical loads are the condensate pumps, the circulating water pumps, and the condenser vacuum pumps being used for the current mode of core cooling: steaming OTSG "A" to the con-denser on natural circulation. In addition to these primary cooling mode equipments, the secondary services closed cooling water pumps and the new high pressure pump, LTB-P-1, are necessary for the backup cooling mode. (Long term cooling using forced circulation of the secondary side of OTSG "B"). Upon less of offsite power to the BOP buses, the BOP diesel generatore and/or the combustion turbines via the 10 MVA transformer can adequately supply the electrical loads associated with either of the above core cooling modes. II. TECHNICAL BASIS A. A detailed investigation has disclosed the following: 1. An extensive 115 kV system exists and is served by a number of combustion turbines at various locations. 2. An extensive 230 kV system exists and is served by a nurber of combustion turbines at various locations. 3. All combustien turbines have black start capability. Central Dispatch has supervisory control and indication of each unit. The units can be started and ready to carry full load within a ten (10) minute period. l

1 Page 2 4. Suitable transmission lines are available to supply power, through setup transformers, to the TMI 230 kV substation from selected combustion turbines. 5. The location and capacity of the combustion turbines on the 230 kV system available to serve TMI-II during an emergency are as follows: (see Figure 4 and Figure 5) a) Hunterstown 23 MVA units: First choice b) Tolna 23 MVA units: Second choice c) Mountain 23 MVA units: Third choice 6. Suitable stepup transformers are available at both Jackson and >Hddletown junction to serve TMI-230 kV substation at the required 230 kV voltage. 7. Power from the TSR 230 kV substation can be used to energize either of the auxiliary transformers at TMI-II (See Figure 5). S. Both the combustion turbines and associated transmission lines are readily available for service. 9. Based on historical data, it has been determined that over the past five (5) years there has been a high degree of reliability relative to forced outages of the 115 kV and 230 kV transmission lines and associated substations. B. Conclusion 1. Documentation of the reliability of the lines and substations associated with the 115 and 230 kV routes has been compiled and is shown in Exhibit A. This data is based on the five (5) year forced outage records as obtained from the Metrepolitan Edison Disturbance Reporting System. 2. As shown in Table 1, the necessary load for any core cooling mode is well within the 46 MVA capacity available from any combustion turbine site. The current TMI-II station service load for all auxiliaries is approximately 8 Mh'. 3. Exhibit 3 provides the procedural guidelines for making combustion turbine power available to I?E-II in an emergency situation. As indicated by the attached letter from Mr. H. J. Slater, Superintendent System Dispatching to all system load dispatchers and the TMI-II t

Page 3 Operations >bnager, the procedures are to be implemented promptly upon loss of offsite power. These procedures will go into effect as soon as formal approval has been received. 4. Upon farmal approval for the utilization of the existing CT's, transmission and transformation equipment, and the TMI-II auxiliary transformers as an acceptable emergency backup supply for IMI-II, the procedures referenced in Exhibit 3 will be implemented and the leased diesels and 10 MVA transformer will be removed. l l l l
