31
Q

Who can N/A not needed steps in the IOI?

A

Shift supervision ( shift manager/CRS)

32
Q

How do you verify all rods in after a scram?

A

push raw data button (not by looking at all green lights)

33
Q

what should be done if an uncoupled rod is observed?

A

enter CRD malfunction ONEP (05-1-02-IV-1)

34
Q

What is the minimum Rx period?

A

90 seconds

35
Q

what should be done if too short of a Rx period is observed?

A

Insert all control rods to increase period

36
Q

when should you go to single notch withdrawal?

A

10 times initial count rate

37

A

tech spec 100 deg F

admin 90 deg F

38
Q

what temp should feedwater temp be maintained at? why?

A

> 70 deg F, to protect the FW flued heads

39
Q

what should drywell pressure be maintained at?

A

< 1 psig

40
Q

what is Keff when Rx is exactly critical?

A

Keff = 1

41
Q

What is reactor period definition?

A

time it takes for initial neutron population to change from some initial value to “e” (2.718) times that initial value. Period is measured is seconds.

42
Q

What is reactor period if there is no change?

A

infinity

43
Q

What is doubling time?

A

time taken for neutron population to double

44
Q

RX period calculation?

A

RX period = DT x 1.44

45
Q

reactor period

A

change in neutrons from one generation to the next

46
Q

criticality

A

increase in counts with no rod motion

47
Q

approaching criticality? (Control rods_)

A

use single notch control rods

48
Q

criticality is expected when?

A

criticality is expected at any time after the first rod is not full in

49
Q

M3?

A

required prior to mode 3 after a hydro pressure test

50
Q

S

A

recommended for startup or mode 3

51
Q

calculate period

A

1.44 x Doubling time

52
Q

heatup/cooldown plots

A

don’t exceed 90F admin and 100F TS (taken every 15 minutes)

53
Q

Begin single notch withdrawal when?

A

at 10 times the initial SRM count rate
