ELHCTRICAL P00ER SYSTDES SURVEILLANCE REQUIRDENTS (Continued) 2.
Verifying the generator capability to reject a load of 1515 kw without tripping.
- 3.
Simulating a loss of offsite power in conjunctics with Reactor Building l high pressure and Reactor Building high-high pressure tests signals, 3
and; a) Verifying de-energization of the emergency buses and load
{
shedding from the emergency busses,
)
b) Verifying that the 4160 v. emergency bus tie breakers open, c)
Verifying the diesel starts from ambient condition on the auto-start signal, energizes the emergency busses with permanently connected loads, energizes the auto-connected emergency loads through the load sequencer, and operates for 15 minutes while its generator is loaded with the emergency loads.
- 4.
Verifying the diesel generator oi>erates for at least 60 minutes.
{
During the first 5 minutes but no greater than 6 minutes of this test the diesel generator shall be loaded to greater than or equal to 3248 kw but less than 3300 kw and during the remaining time of this 60 minute test, the diesel generator shall be loaded to grecter than or equal to 2750 kw but less than 3000 kw,
- 5.
Verifying that the auto-connected loads to each diesel generator for the worst case diesel generator operating condition do not exceed 3248 kw, and 6.
Verifying that the automatic load sequence timers are OPERABLE with each load sequence time interval within : 104.
- This test shall be performed in MODE 3
- These revised requirenents shall apply only until the e.nd of Cycle VII.
