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 I 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.

Refueling Operations
1.0 OPERATIONAL REQUIREMENTS - DECAY TIME
1.1 The reactor shall be subcritical for a minimum period of time as
determined by Table A.
APPLICABILITY: During movement of irradiated fuel in the reactor vessl.
ACTION:
With the reactor subcritical for a time less than determined by Table A,
suspend all operations involving movement of irradiated fuel in the
reactor vessel. Fuel movement in the reactor vessel may continue
provided the minimum decay time is greater than the time shown on.'
Table A.
2.0 SURVEILLANCE REQUIREMENTS 2.1 The reactor shall be determined to have been subcritical for a minimum
period of time as determined using Table A by verification of the date
and time of subcriticality prior to movement of irradiated fuel in the
reactor vessel.
2.2 CCW temperature shall be monitored every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> during the movement of
fuel in the reactor vessel to ensure the temperature used to determine
decay time is not exceeded.

NOTE 1: - Linear interpolation between listed points is acceptable.
NOTE 2: - These delay times are applicable to end of cycle full core off-loads only. A
mid-cycle core off-load assumes two CCW and Fuel Pool Cooling trains
available and does NOT require compliance with these limits.
NOTE 3: - Effective CCW temperature refers to actual CCW heat exchanger outlet
temperature plus 5oF.
NOTE 4: - The table assumes the core off-load duration is 39 hours4.513889e-4 days <br />0.0108 hours <br />6.448413e-5 weeks <br />1.48395e-5 months <br /> or greater.

When direct communications between the control room and personnel at the
refueling station cannot be maintained, suspend all CORE ALTERATIONS.
4.0 SURVEILLANCE REQUIREMENTS:
4.1 Direct communications between the control room and personnel at the
refueling station in containment shall be demonstrated within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />

ALTERATIONS.
5.0 OPERATIONAL REQUIREMENTS - REFUELING MACHINE
5.1 The refueling machine and auxiliary hoist shall be used for movement of
drive rods or fuel assemblies and shall be OPERABLE with:
a. The refueling machine, used for movement of fuel assemblies, having:
1. A minimum capacity of 4000 pounds, and
2. An automatic overload cutoff limit less than or equal to 2700
pounds.
The auxiliary hoist, used for latching and unlatching drive rods, having:
b.
1. A minimum capacity of 3000 pounds, and
2. A 0 - 2000 pound digital load indicator that shall be used to
monitor loads to prevent lifting more than 600 pounds.
APPLICABILITY: During movement of drive rods or fuel assemblies within the
reactor vessel.
ACTION:
With the requirements for the refueling machine and/or auxiliary hoist
OPERABILITY not satisfied, suspend use of any inoperable refueling
machine and/or auxiliary hoist from operations involving the movement of
drive rods and fuel assemblies within the reactor vessel.
6.0 SURVEILLANCE REQUIREMENTS 6.1 The refueling machine used for movement of fuel assemblies within the
reactor vessel shall be demonstrated OPERABLE, within 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> prior to
the start of such operations, by performing a load test of at least 4000
