1 Transportation Certification Branch Approval Record Model No. BU-7 Packaae Docket No. 71-9019 By application dated November 13, 1984, as supplemented April 29, 1985, General Electric Company (GE) has requested several small changes to the Model No. BU-7 ~ package. Among other things, these changes include dimensional changes to the outer and inner drums (adding tolerances) and inner drum gasket testing changes.
GE reauests dimensional changes be approved for the !!odel No. BU-7 shipping container. Those changes that can affect criticality are the inner container increasing its inner diameter from 13.75 to 14.05 inches and the inner height from 26.75 to 27.25 inches. Thus, the inner container volume increases about 6.5 percent. . All contents are to remain identical as per previous approvals. Thus, these contents fill the extra volume and the expected increase in keff is about 2.5 percent in units of keff.
GE used the same criticality methods (KEN 0 IV with the Hansen-Roach 16-group cross section set, successfully benchnarked against appropriate criticals) that were used.in establishing subcriticality of the Model No. BU-7 with old inner container dimensions with identical fissile i contents.
The maximum koo (202 kg U(4)0 9 ) per tiodel No. BU-7 container 60% resin density, H/U = 1.58, C/U = 1.260 was calculated to be 0.913 +-0.005 for normal conditions, maximum reactivity. The corresponding naximum keff for 256 damaged (9x9x4) H7 0 reflected with maximum interspersed moderator was calculated to be 0.955 + 0.005. The maximum keff for a single (70 kg U(4)0 plus 40 w/o water flooding) package-was calculated to be.
0.904_+8).004. .
The staff has reviewed the KEN 0 IV input and output for selected cases and found them to be accurate and representing the cases intended.

e The GE Orawing No. 11201592, Revision 4, shows the use of a 1/8-inch thick silicone rubber gasket with a har.dness range of 45 to 75 durameter.
Test results have been included to demonstrate the acceptability of the proposed gasket material. . However, the reuse of the gasket material has not been satisfactorily addressed because only the change in hardness was considered (inspection frequency was not specified). Because of uncertainties in specifying performance criteria for reused gaskets, we have previously required elastomer gaskets to be replaced at least annually. In a new application, we would be wil. ling to consider additional j
infonnation which includes tests for (1) tensile strength, (2) elongation, and (3) durometer hardness. Except for defective gaskets, replacement of gaskets need not be made until after December 31, 1985, in order to allow for a transition time, a n s_-I Charles E. MacDonald, Chief '
