"Source Range N-3 1."
"* The I&C Supervisor states that both control and instrument power must be removed
from the N-31 drawer to replace a bistable module.
Should the control and instrument power fuses be removed AND why or why not?
a.
NO, because removing both fuses will cause the reactor to trip when the fuses are
removed.
b.
YES, provided only the instrument power fuses are removed or the reactor will
trip when power is reduced below P-10.
c.
NO, because removing both fuses will cause the reactor to trip when power is
reduced below P-6.
d.
YES, because removing both fuses will NOT cause a reactor trip to occur.
ANSWER:
c.
NO, because removing both fuses will cause the reactor to trip when power is
reduced below P-6.

Attachment 19
Sheet 1 of 9
Makeup Concentration Limits
These tables were derived per calculation HNP-I/INST-1056 using the equations of
Attachment 3 and provide a means to select an appropriate RWMU Total
Makeup Flow Rate (Q) which will yield a desired blended flow boron concentration when
matched to the BAT concentration and the Boric Acid Flow Rate span of 1 to 30 gpm.
It is necessary to select lower RWMU Total Makeup Flow Rates when high boron
concentrations are required because the Boric Acid Flow is limited by system configuration to
a maximum of 33 gpm. This maximum Boric Acid Flow capability however is not used as the
basis for these tables because it is necessary to allow some margin for possible system
performance degradation. Therefore a maximum Boric Acid Flow of 30 gpm is used as the
basis for the following tables.
Each sheet of the tables is applicable to a specific RWMU Total Makeup Flow Rate (Q).
The maximum ppm results have been rounded down to the nearest whole number and the
minimum ppm results have been rounded up to the nearest whole number.

To determine the minimum boron concentration for which makeup will be reliable
at 120 gpm total flow, select the BAT boron concentration which is equal to or
higher than current BAT boron concentration.
