DEFINITIONS J

e CORE ALTERATION 1.7 CORE ALTERATION shall be the addition, removal, relocation or movement of fuel, sources, incore instruments or reactivity controls within the reactor o pressure vessel with the vessel head removed and fuel in the vessel. 3 Suspension of CORE ALTERATIONS shall not preclude completion of the movement 2-of a component to a safe conservative position.

{

CRITICAL POWER RATIO .

_ ,.7 ,_ _. _n _. .a _ t .W') h 1.8 The CRITICAL POWER RATIO (CPR) shall be the ratiofof that power in the assembly which is calculated by application of the-6Ent correlation to cause

/

l some point in the assembly to experience boiling transition, divided by the actual assembly operating power.

DOSE EQUIVALENT I-131 1.9 00SE EQUIVALENT I-131 shall be that concentration of I-131, microcuries per gram, which alone would produce the same thyroid dose as the quantity and isotopic mixture of I-131,1-132, I-133,1-134, and I-135 actually present.

The thyroid dose conversion factors used for this calculation shall be those I.. listed in Table III of TID-14844, " Calculation of Distance Factors for Power and Test Reactor Sites."

DRYWELL INTEGRITY 1.10 DRYWELL INTEGRITY shall exist when:

a. All drywell penetrations required to be closed during accident conditions are either:
1. Capable of being closed by an OPERABLE drywell automatic isolation system, or
2. Closed by at least one manual valve, blind flange, or deactivated automatic valve secured in its closed position, L

nm except as provided in Table 3.6.4-1 of Specification 3.6.4.

i 8 b. The drywell equipment hatch is closed and sealed.

$$ c. The drywell airlock is in compliance with the requirements of ne Specification 3.6.2.3.

m 88 d. The drywell leakage rates are within the Itaits of Specification g4 3.6.2.2.

o g e. The suppression pool is in compliance with the requirements of am. a- Specification 3.6.3.1.

f. The sealing mechanism arsociated with each drywell penetration; e.g. , welds, bellows or 0-cings, is OPERABLE.

Insert 3.2.1 During single loop operation, the APLHGR for each type of fuel as a function of AVERAGE PLANAR EXPOSURE shall not exceed the limits as determined below:

a) for fuel types 8CR210 and 8CR160 - the limit shewn in figure 3.2.1-1 as multiplied by the smaller of either MAPFAC(f), MAPFAC(p) or 0.86; and b) for fuel type XN-1 the Ifmit determined in "a" above for fuel type 8CR210.
