CAL:
5-93-001 Siemens Power Corporation 2101 Horn Rapids Road l
P. O Box 130 Richland, Washington 99352-0130 Attention: Mr. B. N. Femreite, Plant Manager
SUBJECT:
CONFIRMATORY ACTION LETTER Based on the findings of our Augmented Inspection Team during the week of February 8,1993, the NRC has developed a specific concern related to criticality controls for your uranium oxide blending and powder preparation i"
system.
Our concern involves the potential for moderator intrusion into the area of your powder preparation lines 2 and 3, a potential that we feel has l
not received sufficient technical evaluation. We believe this matter deserves your immediate attention, in view of (1) the configuration of the vacuum suction line, (2) the recently demonstrated potential for inadvertent powder spills due to line disconnects, and (3) the presence of water lines in relatively close proximity to the equipment of concern.
Pursuant to a telephone conversation on February 11, 1993, between yourself, F. Wenslawski (Augmented Inspection Team Leader), and Mr. R. Scarano (Director, Division of Radiation Safety and Safeguards), we understand that you have taken (or will take) the following actions:
1.
Siemens Power Corpration will perform an engineering evaluation of the potential intrusion of moderating liquids into the uranium oxide blending and powder preparation system, and define the specific controls necessary i
to prevent criticality.
2.
Pending completion of the above review, and the satisfactory resolution of NRC concerns:
4 a.
Siemens will use an alternate methoc. to manually vacuum trmsfer blended powder (via 45-gallon borated drums) to the powder j
preparation system, and will tag the " accurate" feeder system out of service.
b.
If Siemens elects to use the " accurate" feeder system, Siemens will dedicate, on a continuous basis, a qualified operator at the feeder station to observe operation of the feeder and to be watchful for l
the intrusion of moderating liquids. This operator will be trained in his/her duties and responsibilities relative to this assignment.
i c.
Actions 2.a and 2.b, above, are applicable to Converd on Line 2, I

'l which includes Powder Preparation Lines 2 and 3.
These actions will be in effect as of your receipt of this letter.
i Pursuant to Section 182 of the Atomic Energy Act, 42 U.S.C. 2232, and 10 CFR 2.204, you are required to:
1)
Notify me immediately if your understanding differs from that set forth above, j
2)
Notify me if for any reason you cannot complete the actions within the.specified schedule and advise me in writing of your modified schedule in advance of the chang, and 3)
Notify me in writing when you have completed the actions addressed in this Confirmatory Action Letter.
Issuance of this Confirmatory Action Letter does not preclude issuance of an order formalizing the above commitments or requiring other actions on the part of the licensee. Nor does it preclude the NRC from taking enforcement action for violations of NRC requirements that may have prompted the issuance of this letter.
In addition, failure to take the actions addressed in this i
Confirmatory Action Letter may result in enforcement action.
The responses directed by this letter are not subject to the clearance procedures of the Office of Management and Budget as required by the Paperwork Reduction Act of 1980, Pub. L. No.96-511.
In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter and its enclosures will be placed in the NRC Public Document Room.
