i Siemens Response to NRC RAI Dated 11/12/97 NBC ReayAs 1a) - According to material safety data sheets, sodium hydrosulfite is a flammab% solid and is reactive with small amounts of water. What safety measures are taken when handling - or using sodium hydrosulfite to protect the worker and prevent any undesired reactions? SPC Response la) -While handling the dry sodium hydrosulfite the operator will wear respiratory protection, gloves, and goggles as specified per the material safety data sheet. Many other. protective measures are taken when using this chemical. Sodium hydrosulfite is packaged 'in plastic lined water-tight 220 lb cans, stored in a weather proof chemical storage building equipped with a heat detector, kcpt away from water sources and incompatible chemicals, .and handled in areas having good obtdoor ventilation. A safety shower and cye wash station are provided at the SPF building 30 feet away if needed. To avoid the reaction between dry sodium hydrosulfite and small. amounts of water, the solution is made up by i edding dry sodium hydrosulfite to a large amount of water instead of vice versa. . NRC Reauest 2a) The lagoon uranium recovery (LUR) pr* cessing equipment building enclosure is - described in this section. Will fumes or offgas be generated when using sodium hydrosulfite? If so, how are fumes handled? L SPC Resoonse - 2a) Sulfur dioxide' odors may be detected during aqueous make-up of the sodium _ hydrosulfite solution. This is done in a separate non radioactive chemical make-up room which has good outdoor ventilation through large roll up doors. Dry sodium hydrosulfite is added to 50 gallons of water. The batch of solution is then pumped into a 6000 gallon LUR tank located in the radioactive area at about 1 volume percent. The LUR tanks and building are HEPA filter ventilated with a 2000 cfm building exhauster and 10,000_cfm air recirculation system. Tc date, no sulfur dioxide or odors have been detected at the LUR tankt.due to the low concentration of sodium hydrosulfite.' Industrial hygiene (IH) personnel monitor levels of toxic gases generated during each chemical handling step to establish the appropriate level of protective equipment needed consistent with the MSDS. Any changes to an operation requires an lH evaluation and sampling. NRC Regg.n
- 2b) What is the concentration of sodium hydrosulfite used and stored onsite? Are 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 uranir.1.- [ .}}
