SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION AMENDMENT APPLICATION DATED JULY 30, 1996.AND REQUEST FOR ADDITIONAL INFORMATION RESPONSES DATED JANUARY 28, 1997(TAC NO. L30929)
Dear Mr. Maa's:
This refers to the Siemens application dated July 30. 1996, requesting the revision of License SNM 1227 to include the Solids Processing Facility (SPF) process as an authorized activity for uranium recovery. The NRC staff has identified additional information that is needed before final action can be taken on your amendment request. This additional information is described in the enclosure to this letter.
Normally, a response is requested within 30 days. However, to support an expedited review due to your commitment to the State of Washington to start this process by the end of the year, the additional information should be provided in the form of responses to the individual comments by December 1.
1997. Please reference the above TAC number in future correspondence related to this request.
If you have any questions, please call me at (301) 415 8119.
Sincerely.

- 2) Reference July 30. 1996. submittal, page 2. Buildina Enclosure.
a) The lagoon uranium recovery (LUR) processing equipment building enclosure is described in this section. Will fumes or of fgas be generated when using sodium hydrosulfite? If so, how are fumes handled?
b) What is the concentration of sodium hydrosulfite used and stored onsite? A any other chemicals used in the LUR process? If so. list where they are used, the concentration, the method of storage, and whether or not the chemicals come in contact with uranium. -
c) Is heat added during processing and are any fumes generated during heating?
d) Please provide the balanced equation, along with the mass and heat balance for the reaction of sodium hydrosulfite and uranium.
e) How is process piping and equipment integrity maintained in the LUR facility to ensure containment of both hazardous and energized material?
- 3) As described in the July 30, 1996, submittal, have there been any changes made to the approved LUR process? If so, describe any changes and their impact on safety.

Please provide details of tests and frequencies, d) If a temperature controller fails, what is the maximum temperature expected in the feed tank? Material safety data sheet information indicates that sodium nitrite is unstable with heat. At this maximum temperature, are there any hazards with the sodium hypochlorite, sodium nitrite, and the lagoon water? Please provide details of how these hazards were evaluated.
- 6) Reference January 28, 1997. revised LUR/SPF process flow diagram.
a) The SPF process flow diagram indicates the presence of Chem Additive tank T-673. Is this where sodium hypochlorite and sodium nitrite are stored?
b) What is the temperature, pressure, composition, concentration, and flowrate of the additives stream? Provide the mass-balance for input and output streams for tank-673.
c) Are chemicals stored in a cool, dry, and well-ventilated area, away from incompatible chemicals?
d) Are personal protective equipment (e.g., goggles face shields, gloves) and safety equipment such as: respirators. safety shower / eye wash stations and fire fighting equipment readily available for these chemicals?
- 8) Reference January 28. 1997, revised LUR/SPF process flow diagram.
a) Please provide: balanced equations for reactants and products, mass and heat balances, and predicted operating temperatures and pressures for the reactions with uranium and chnmical additives in tank T-670.
4 3 b) Identify hazards and corresponding safety controls for normal and accident conditions associated with chemicals in the LUR/SPF process? ,
List chemicals and related controls. Explain how these safety controls !
are maintained and tested to ensure they are available and reliable?
c) How is process piping and equipment integrity nx tatained in the SPF facility to ensure containment of both hazardous and energized material?
d) _W hat is the operating pressure of: strainers F-675. filters F 6/4 and filter press F-6707 What safety measures are taken to protect workers if filters or strainers become blocked due to solids accumulation and material leaks out under high pressure? Are these safety devices tested to ensure their availability and reliability in the event of blocked filter or strainer? If so. provide details.
