1.6.1 Q'JALRAliT PC'JER TILT Quadrant power tilt is defined by the follcwing equation and is expressed in percent.

100 Power in any core quadrant Average power of all quadrants -1 The quadre.nt tilt limits are stated in Specification 3.5.2.h.

1.6.2 EEACTOR PC'JER I!ELA';CE Heactor power imbalance is the power in the top half of the core minus the power in the bottom half of the core expressed as a percentage of rated power. Intalance 13 monitored continuously by the RFS using input from tre power range channeln.

Imbalance limits are defined in Specification 2.1 and imbalance setpointu are defined in Grecification 2.3 17 CO!!TAItiME'iT IIITEGRITY Containment integrity exists when the following conditions are satisfied:

a.

The equipment hatch is closed and sealed and both doors of the personnel hatch and emergency hatch are closed and sealed except as in "b" or "f" below, b.

At least cne door on each of the personnel hatch and emergency hatch is closed and sealed during refueling or personnel passage through these hatches.

c.

d.

Ill automatic containment isolation valves are operable or locked closed.

Section L.L.l.2.hb in the event corrective action ic required by local leak rate test results.

The probability of occurrence or the consequences of an act : dent or malfunction of equipment 1=portant to narety previously evaluated in the cafety analysis report in not increaced in that the other door will be leak tested and meet the local leak rate criteria fcr door sealn prior to performing any maintenance.

The margin of safety defined in the banes for.ny technical specification la not reduced in that thin change will clarify Section 1." to allow a h8 hour maintenance time for preventive or corrective maintenance other than that corrective taintenance required by local leak rate test results.
