LIMITING CONDITION FOR OPERATION i
3.3.1 As a minimum, the Reactor Trip System instrumentation channels and interlocks of Table 3.3-1 shall be OPERABLE with RESPONSE TIMES as shown in Table 3.3-2.
APPLICABILITY:
As shown in Table 3.3-1.
ACTION:
As shown in Table 3.3-1.
l SURVEILLANCE REQUIREMENTS 4.3.1.1 Each Reactor Trip System instrumentation channel and interlock and the automatic trip logic shall be demonstrated OPERABLE by the performance of the Reactor Trip System Instrumentation Surveillance Requirements specified in Table 4.3-1.
4.3.1.2 The REACTOR TRIP SYSTEM RESPONSE TIME of each Reactor trip f hsd. ion c
shall be demonstrated to be within its limit at least once per 18 mo Each test shall include at least one train such that both trains are at least once per 36 months and one channel per function such that all channels
)
are tested at least once every N times 18 months where N is the total number of redundant channels in a specific reactor trip function as shown in the
" Total No. of Channels" column of Table 3.3-1.

At least once every 31 days by obtaining a sample of fuel oil in accordance with ASTM-D2276-78, and verifying that total particulate i
contamination is less than 10 mg/ liter when checked in accordance I
with ASTM-D2276-78, Method A; j

' Subjecting the diesel to an inspection, during shutdown, in l
accordance with procedures prepared in conjunction with its l
man ecommendations for this class of standby vice; (, )
s 2)
Verifying the generator capability to reject a load of greater than or equal to 825 kW while maintaining voltage at 4160 1 420 volts and frequency at 60 1 1.2 Hz; i
3)
Verifying the generator capability to reject a load of greater than or equal to 5600 kW but less than or equal to 5750 kW without tripping.
The generator speed shall not exceed 500 rpm-during and following the load rejection; 4)
Simulating a loss-of-offsite power by itself,** during shutdown, p
and:
a)
Verifying deenergization of the emergency busses and load shedding from the emergency busses, and b)
Verifying the diesel starts on the auto-start signal, energizes the emergency busses with permanently connected loads within 11 seconds, energizes the auto-connected emergency (accident) loads through the load sequencer and operates for greater than or equal to 5 minutes while its generator is loaded with the emergency loads.
After ener-gization, the steady-state voltage and frequency of the emergency busses'shall be maintained at 4160 1 420 volts and 60 1 1.2 Hz during this test.
i 5)
Verifying that on an ESF Actuation test signal, without loss-of-offsite power, the diesel generator starts on the auto-start signal and operates on standby for greater than or equal to 5 minutes.
The generator voltage and frequency shall be at i
4160 t 420 volts and 60 1.2 Hz within 11 seconds after the l
auto-start signal; the steady-state generator voltage and j
frequency shall be maintained within these limits during this j
