' Nov::bar 10, 1997 Mr. Steven Toelle, M: nager Nuclear Regulatory Assurance and Policy U. S. Enrichment Corporation
. 2 Democracy Center 3903 Rockledge Drive Bethesda, MD 20817
SUBJECT:
PADUCAH GASEOUS DIFFUSION PLANT, COMPLIANCE PLAN ISSUE 3 ACTION 9, ASME CODE INTERPRETATION AND ASSESSMENT RESULTS (TAC NO. L32012)
Dear Mr. Toolle:
The purpose of this letter is to clarify and supplement our October 10,1997, letter to you on the above subject.
Neither our letter or your engineering assessment, submitted by letter dated December 31, 1996, addressed the issue of thin walled cylinders. B3cause there is no prohibition on using thin walled cylinders in the C-360 parent-daughter transfer system, these cylinders must be considered in any assessment. The allowable working pressure for thin walled cylinders is only 100 psig compared to the 200 psig for thick walled cylinders. The technical justification contained in the engineering assessment is inadequate to support your argument that pressure relief protection is not necessary for the parent-daughter transfer operation, particularly with respect to the thin walled cylinders. Therefore, your response to our October 10,1997, letter should also address the use of thin walled cylinders.
I also note that Portsmouth must address the issue of pressure relief for UF6 cylinders.
Although the Compliance Plan item is not due until May 1,1998, it is reasonable to assume that ASME will respond in a similar manner. I suggest that USEC pursue a joint Portsmouth and Paducah resolution to the issue of pressure relief, if you have questions, please contact Ms. Merri Horn of my staff.
Sincerely, .
