BASES 1.1 REACTOR TRIP SYSTEM RESPONSE TIMES The bases for the Reactor Trip System are contained in the CPSES Technical i

Specifications. The measurement of response time at the specified frequencies provides assurance that the Reactor trip actuation associated with each channel i

is completed within the time limit assumed in the safety analyses. No credit was l

taken in the analyses for those channels with response times indicated as not applicable. Response time may be demonstrated by any series of sequential, overlapping, or total channel test measurements provided that such tests demonstrate the total channel response time as defined. Sensor response time verification may be demonstrated by either:

(1) in place, onsite. or offsite test measurements, or (2) utilizing replacement sensors with certified response time.

TABLE NOTATIONS

  • Identification code for containment penetration and associated isolation valves in FSAR Tables 6.2.4-1, 6.2.4-2. and 6.2.4-3.
  1. May be opened on an intermittent basis under administrative control.

The table does not list local vent, drain and test connections as they are a 14 special class of containment isolation valves and are locked closed to meet containment isolation criteria when located within the penetration boundary.

These valves are subject to the same leak rate testing as the other containment isolation valves in the associated penetration including all applicable leak testing exceptions (see FSAR Table 6.2.4-2 ircluding notes). In addition, if i

these valves are capped (or isolated by blind flange) and under administrative controls they are not required to be leak rate tested.

Note 1:

All four MSIV bypass valves are locked closed in Mode 1. During Mode 2.

3. and 4 one MSIV bypass valve may be opened provided the other three MSIV bypass valves are locked closed and their associated MSIVs are closed.

Note 2:

These valves require steam to be tested and are thus not required to be tested until the plant is in MODE 3.

Note 3:

These valves are included for table completeness: the requirements of Specification 3.6.3 do not apply.

Instead, the requirements of 3

Specification 3.7.1.1. 3.7.1.5. 3.7.1.6 and 3.7.1.7 apply for main steam safety valves, main steam isolation valves, feedwater isolation valves and steam generator atmospheric relief valves, respectively.

Note 4:

These valves are leak tested in accordance with Technical Specification 2

Surveillance Requirement 4.6.1.2.

Note 5:

10 CFR 50 Appendix J. Type C testing of these valves is satisfied by the testing of the airlock under Technical Specification Surveillance 6

Requirement 4.6.1.3b.

Note 6:

These valves are considered an integral part of the airlock associated with their respective airlock door. Therefore, they are subject to the 6

controls of Specification 3.6.1.3.

Note 7:

These valves are secured in position by hydraulic system locks and/or interlocks and do not require separate locks.

6 Note 8:

Including the instrumentation delays of the containment ventilation 21 isolation signal from Pressurizer Pressure Low.
