d' Request for Additional Infon:'ation Podel No. ORNL Garden Carrier No. 2 Docket fM. 71-6088 JUL 2 81982 Encl to ltr dtd:
STRUCTURAL Provide analysis of the containment system for nomal and hypothetical accident conditions. The effect of these conditions on the containment system must be detemined to evaluate the containment systen perfomance.
CONTAI!UtENT 1.
Establish containcent criteria for nomal fom material for the package containment system. The criteria should be based on type and fom of material; it should be detemined for nomal and hypothetical accident conditions. Regulatory Guide 7.4 may be used to establish containment criteria.
2.
Identify the specific containment systems that will provide containment for nomal fom material. Each of the nomal fom containment system designs cust satisfy the established containment criteria for nomal and hypothetical accident conditions. Containers that neet special fom requirenents are considered non-dispersible under the nomal and hypothetical accident conditions; therefore, satisfying special fom requirements satisfies containment. Containers for plutonium exceeding 20 Ci must meet the requirements of 10 CFR 971.42.
TESTING AND I:AINTENAfiCE Show that the sensitivities and testing schedules for nomal fom materials are adequate for safe use of the packages. Regulatory Guide 7.4 may be used for periodic testing. For assembly verification it is recomended that a test of sufficient sensitivity to limit the maximum release to a type A quantity in 10 day 3 e used; however, a leak test sensitivity b
greater than lx10~3 Th' "iai"""
sengitivity of lx10~jt-cm /s5c " "ld " t b* r*4"ir'd-atm-cm /sec (air at 1 atm and 25'C leaking to a 10~ atm ambient) as specified in ANSI H14.5 should be met.
