B -- ENVIRONMENTAL STUDIES AND ASSESSMENTS POC Anthony Tafoya (505) 667-6296. Los Alamos National Laboratory (LANL) has issued a request for qualifications for a Radioactive Liquid Waste Treatment Facility -- TA-53. BACKGROUND -- Radioactive liquid waste (RLW) is generated during accelerator operations at Los Alamos National Laboratory (LANL) Technical Area (TA)-53. Accelerator operations are managed by the Accelerator Operations and Technology (AOT) Division of LANL. The RLW stream contains tritium and short-lived radionuclides and may potentially contain heavy metals and organics. The RLW stream is currently managed by allowing radionuclides to decay in TA-53 holding tanks, followed by discharge into lagoons where passive evaporation of the water occurs. LANL intends to discontinue use of the lagoons, and as a result, a new RLW treatment scheme must be developed and implemented. The system functions include: collection/segregation, storage treatment, transportation offsite (if required), disposal of final waste form(s), and sampling/analysis. SCOPE -- LANL is issuing this Request for Qualification for addressing radioactive liquid wastes generated at TA-53 by LANL AOT Division. Work includes treatment of radioactive liquid waste and disposal of any secondary waste streams. All secondary waste streams must be disposed of at approved disposal facilities. The overall function of this project is to cost-effectively and properly manage the radioactive liquid waste generated by AOT. The unit operations comprising the treatment system will be recommended by the vendor. Discharge of treated wastewater at TA-53 will not be permitted. The TA-53 treatment system will be provided with necessary utilities and a building space adequate to house the treatment unit. Waste management options for the treatment system design and operation may include: OPTION I -- 1. Onsite treatment of primary waste using a system with: equipment designed, fabricated and installed by the vendor, and operation of the treatment facility by the vendor. 2. Under this scenario, the secondary waste may be disposed as low-level solid radioactive waste at LANL TA-54 Area G or transported, treated, and disposed at an off-site facility approved by LANL. OPTION II -- 1. Partial onsite treatment of the primary waste using a system with: equipment designed, fabricated and installed by the vendor, and operation of the treatment facility by the vendor. 2. Additional offsite treatment of the primary waste. 3. Under this scenario, the secondary waste may be disposed as low-level solid radioactive waste at LANL TA-54 Area G or transported, treated, and disposed at an off-site facility approved by LANL. OPTION III -- 1. Treatment and subsequent disposal of the radioactive liquid waste at an offsite treatment, storage, and disposal facility approved by LANL. OPTION IV -- 1. Recirculation of RLW within the existing cooling system with subsequent storage, treatment, and/or disposal by means of Options I-III detailed above. 2. Under this scenario, the radioactivity of the RLW would be allowed to increase to an acceptable level. The acceptable level will be determined by AOT personnel based on safety concerns and water quality performance criteria. 3. It is anticipated that this scenario would still require a building structure housing, at a minimum, storage tanks and associated ancillary equipment. In addition, containment systems and monitoring equipment may require modifications based on increased radioactivity of the RLW within the cooling system. REGULATORY REQUIREMENTS -- The vendor will manage RLW consistent with LANL policies and procedures including LANL Environmental Safety and Health Division requirements and Facilities, Security & Safeguards Division requirements. Additionally, the treatment system must comply with applicable state and federal requirements regulated by the State of New Mexico, the Environmental Protection Agency, Department of Energy, and Occupational Safety and Health Act requirements. The vendor will be required to support LANL with all licensing, permitting and compliance activities. SUBMITTAL REQUIREMENTS -- Vendors must provide qualifications and project histories with references which are relevant to radioactive liquid waste treatment system design, fabrication, installation, and operation. In addition, vendors should demonstrate experience with ventilation and containment systems that ensure that radiation exposures are As Low As Reasonably Achievable and that workers, the public, and the environment are protected from hazardous and radioactive materials. The entire package must not exceed 15 pages at 12 point font. Vendor response must be received by August 1, 1997. Please mail response to: Los Alamos National Laboratory, P.O. Box 1663, M/S P274 (Attn: Anthony Tafoya), Los Alamos New Mexico, 87545. This Request for Qualifications should not be construed as a commitment or authorization to incur any cost in anticipation of a requ~irement. (0196)
