Letter, L.J. Maas to N.L. Osgood, "Model SP 1 and SP-2 Packages," dated July 8, 1999 in our original application (reference 1) to amend NRC Certificate of Compliance 9248, Siemens Power Corporation (SPC) analyzed the use of the renamed SP-3 shipping container for fuel assemblies and fuel rods as described in paragraphs 5(b)(1)(i),5(b)(1)(ii) and 5(b)(1)(iv) of the certificate. What follows is our analysis of the SP-3 container using a more specific fuel assembly description and applying the necessary analysis to the use of polyethylene shims as requested in recent conversations.
As a result of conversations you have had with C.D. Manning of SPC regarding the information provided by SPC in references 3 and 4, SPC is amending the application for the shipping containers that were renamed as SP-3 in reference 1. Accordingly, we are submitting six copies of EMF-1563 revision 10 which incorporates the new criticality safety evaluation mentioned previously and incorporated as a revised Appendix 6H. As a result of this evaluation, SPC is requesting an amendment to Certificate of Compliance 9248 to include this 9907290172 990727 PDR ADOCK 07109248 C
