Windsor, Connecticut
SUBJECT:
REVIEW 0F AMENDMENT APELICATION DATED MAY 11, 1981 AND ITS REVISION DATED JULY 14~'1981 I.
Background
Combustion Engineering (CE), by application dated May ll,1981 and its revision dated July 14, 1981, requested authorization to store sealed fuel rods in a 3.7 inches thick slab array in the Development Department's Building No. 2 vault at the Windsor site. All the fuel storage criteria authorized in the Development Department's facilities have been limited to a sife mass as a functiu6 of 2350 enrichment independent of fuel piece dimensions, contain6r gaametry, and degree of water moderation and reflection.
II. Discussion A.
Nuclear Criticality Safety An infinite slab thickness of 3.7 inches has been previously authorized in the Nuclear Fuel Manufacturing facilities for fuel rods having an enrichment < 4.1% 235 This slab thickness 0
of fuel cannot be made critical independent of the fuel rod size and the degree of water moderation and reflection. To minimize the nukber of controls required to assure nuclear safety c' the array of rods, all fissile material in the vault will be stored in the single, 3.7 inches thick array.
i B.
Radiological Safety and Environmental Effects Since all the fuel material in Building No. 2 vault will be in the fem of sealed rods, and only radiological safety controls and procedures currently authorized will be used, there will not be a significant change in radiological safety nor in the environmental effects.

Combustion Engineering C.
General The amendment application and its revision were discussed with Mr. Jerome Roth, Region I (IE) spector of the CE facility on August 10, 1981. He foresaw no safety related problem with authorization to store sealed fuel rods (< 4.1% 2350 enrichment) in the Development Department's Building No. 2 vault in a 3.7 inches thick slab array.
III. ConclQsion The storage of sealed fuel rods in the Development De;Mrtment's Building No. 2 vault in a 3.7 inches thick slab array provides an adequate margin of safety for the protection of the health and safety of the operating personnel, the public, and the environment.
Issuance of the license amendment is recommeded.
