PENT Af!D FINDING OF NO SIGNIFICANT IMPACT 1he U.S. !Juclear Regulatory Cornission (the Consission) is considering the issu6nce cf en atiendr.ent to Facility Operatir.g License No. NPF-47 issued to Gulf Statn Utilities Conpany, (the licensee), for operatior, cf the Ftver 4

water covtrage for irradiated fuel and control rods during their h6ndlirs.'
The proposed action is it, accordance with the licensee's application for arendrer t dated August I?, !?ff.
f:eed for the Frcppo, sed Action The proposed chance to the TS is required to relieve the licensee from the unnecessary hardship dut to the narrow cperatil.g bands for pool levels in the containtier.t and fuel building. The narrow operating barids have siade it difficult to a.aintain the pool levels where the high or low water level annunciators are not actuated. The proposed actier wculd also perrnit an

2 easier transfer through the fuel transfer shield and would permit placing control rods on hangers provided for their storage in the fuel building pool.
Environmenta Q Lacts of the proposed Action The Commission has completed its evaluation of the proposed revisions to the Technical Specifications. The proposed revisions would reduce the minimum i
l water coverage above a single spent fuel assembly in the storage pool from 8 feet 6 inches to 8 feet 2 inches, and above an irradiated control rod from 8 feet ( inches to 6 feet 9 inches.
TS 4.9.6.1 would be modified to require demonstration that the normal uptravel stop interlock of the refueling platform main hoist maintains at least 8 feet 2 inches of water coverage above the' top of the active irradiated fuel and that the normal uptravel stop interlock of the frame-mounted and mencrai'-meunted auxiliary hoists maintain at least 6 4
feet 9 inches of water coverage above the top of the irradiated control rod, s
j The surveillance requirerents of TS 4.9.6.2 would be modified in a similar manner to require demonstration that the normal uptravel stop interlock en the fuel handling platform main hoist maintains at least 8 feet 2 inches of water coverage above the top of the active irradiated fuel and that the normal uptravel stop interlock of the monorail-mounted auxiliary hoist maintains at least E feet 9 inches of water coverage above the top of the irradiated control rod.
The pool water (as well as the water level above the reactor pressure vessel flange) will remain unchanged at a minimum of 23 feet above the spent fuen in the storage racks. Therefore, the proposed change would not increase the probability or consequences of any accident previously evaluated.

.. I Ttt licensee estimattd a radiatier. dose rate increase to personnel on the refuelir.s platform of 0.2 inrem per hour due to the reduction of water coverage f
atove the active zene of the irradiated fuel and 0.3 r. rem per hour fron are s

In addition, the licensee estiri.ated that personnel l
l radittien exposure over the plar.t design life would iricrease by 0.2 man-Ren frcr.irrediated fuel and 0.01 r.an-Ren from irradiated control rods. Thus, I
lr thers is r,o significent increase in the allowable individual or curolative a
occupatienal radi6 tion exposure.
