IOI-6 Reactor Vessel In-Service Leak Test

Question 1

State the purpose of IOI-6 Reactor vessel in-service leak test

Answer 1

to provide directions to perform a system leakage test of the reactor vessel AND associated class 1 and 2 piping

Question 2

state the reactor vessel temperature at which primary and secondary ctmt must be established

Answer 2

200F unless the secondary CTMT and SBGT operability requirements of tech spec 3.10.1 are met

Question 3

state the maximum pressure rate change allowed by IOI-6

Answer 3

<50#/min

Question 4

state who is allowed access into the drywell while performing IOI-6

Answer 4

limited to personnel directly involved in the test or cleared by shift supervision

Question 5

explain the required actions if RPS power or pressure control using G33-F033 (RWCU blowdown) is lost

Answer 5

CRD pumps must be tripped immediately to prevent over-pressurizing the vessel

Question 6

state the limits places in the recirc pumps while performing IOI-6 reactor vessel in-service leak test.

Answer 6

flow control valve <20%

motor amps <610 amps

Do not exceed 44,500 gpm flow loop
