Description

SRS Tour announcement 1.0 Description 1.1 The Department of Energy (DOE) is seeking input from commercial industry to help identify the optimal system, structure or component (SSC) to safely contain and disposition low level nuclear waste in the form of Saltstone. The goal of this inquiry is to ascertain from industry experts the most cost effective and timely way to design and construct SDUs with sufficient capacity to maintain uninterrupted liquid waste processing at the Savannah River Site (SRS). 1.2 This is a Request for Information (RFI) only. This RFI is issued solely for information and planning purposes - it does not constitute a Request for Proposal (RFP) or a promise to issue an RFP in the future. This request for information does not commit the Government to contract for any supply or service whatsoever. Further, the Department of Energy (DOE) is not at this time seeking proposals and will not accept unsolicited proposals. Respondents are advised that the U.S. Government will not pay for any information or administrative costs incurred in response to this RFI; all costs associated with responding to this RFI will be solely at the interested party's expense. Not responding to this RFI does not preclude participation in any future RFP, if any is issued. If a solicitation is released, it will be synopsized on the Federal Business Opportunities (FedBizOpps) website: https://www.fbo.gov. It is the responsibility of the potential offerors to monitor these sites for additional information pertaining to this requirement. 2.0 Background SRS processes and stores nuclear materials in support of national defense and U.S. nuclear nonproliferation efforts. One of its missions is to treat nuclear and hazardous wastes left from the Cold War. The SRS Liquid Waste (LW) System is the integrated series of facilities that safely manage the existing waste inventory and disposition waste stored in tanks into a final glass or grout form. This system includes facilities for storage, evaporation, waste removal, pre-treatment, vitrification, and disposal. The mission of the Saltstone Facility in Z-Area is to process and dispose of radioactive waste salt solution (Decontaminated Salt Solution (DSS)) from the tank farm. Built in the 1980s, the Z-Area Saltstone Facility immobilizes the low level radioactivity waste salt solution by mixing it with a dry material mixture of fly ash, slag, and cement to produce a flowable grout mixture. This grout is poured into large concrete disposal units, where it cures to become Saltstone, a leach-resistant solid monolith, for permanent disposal. The Saltstone Facility consists of two facility segments: The Saltstone Production Facility (SPF) and the Saltstone Disposal Facility (SDF). The SPF receives the DSS, produces the grout, and transfers the grout. The SDF disposes the grout in Saltstone disposal units (SDUs). The SDF is permitted by the South Carolina Department of Health and Environmental Control (SCDHEC) as an Industrial Waste Landfill for disposal of nonhazardous solid waste. The Saltstone monolith provides primary containment for the radionuclides and chemicals in the DSS and the SDUs provide secondary containment. Once all SDUs are filled and closure activities are complete, a backfilled engineering closure will be placed above the SDUs within the SDF providing tertiary containment consistent with all applicable regulations. These disposal cells and the Saltstone matrix are not expected to release any significant amount of radionuclides over the 1,000-year compliance period. It is anticipated that an additional 200Mgal of Saltstone will have to be dispositioned before SRS completes its LW disposal mission. The first SDU (Vault 1) is approximately 100 feet wide by 600 feet in length by 25 feet in height, divided into six cells and the second SDU (Vault 4) is approximately 200 feet wide by 600 feet in length by 26 feet in height, divided into twelve cells. Neither is planned for future use in emplacing contaminated grout. SDU-2, SDU-3, and SDU-5, currently in use, consist of two cells, each cell nominally 150 feet diameter by 22 feet high each. This design is used commercially for storage of water. After accounting for interior obstructions (support columns, drainwater collection systems, etc.) and the requirement for a 2-foot cold cap, the nominal volume of a cell is 2.9 Mgal. The current disposal cell being constructed, SDU-6 will be a 375-foot diameter 43-foot tall single-cell design. The unit will have a nominal volume of hold 32 Mgal. For every 10Mgal of disposal capacity, a leak detection system is required to monitor the disposal cell during operations. In addition to the disposal cell, other infrastructure in necessary to connect to and operate with SPF. This infrastructure known as balance of plant (BOP) includes: • Grout distribution system • Temperature monitoring • Drain water system • Power, Cameras, Lighting • Ventilation Skid • Modular Instrument/Electrical Equipment Skid (MIEES) • Tie-ins 2.1 Constraints a. Design Since the SDUs are meant to be the final disposition location for low level nuclear waste, there are a number of requirements that must be met to assure these disposal cells can safely contain Saltstone for the long term. These requirements are as follows: • Seismic Design Category (SDC)-2 Limit State D criteria • Leak detection system for every 10 Mgal of disposal capacity • Roof thickness should be between 8 to 12 inches depending on the method to prevent long term water infiltration • Must pass fluorescent dye water tightness test with no visible fluorescence • Obtain construction permit from the State of South Carolina • Roof must have sufficient structural integrity to support BOP SSCs, penetrations, and allow personnel access for daily operational rounds and BOP maintenance • Individual SDU operational life (before closure cap is installed) 25 years • The Saltstone grout may include high levels of chemicals which may adversely affect the disposal cell (for example sulfates and sodium hydroxide) • Grout Temperature: 10°C to 100°C • Grout density is typically 1.76 g/ml • Relative humidity up to 100% condensing within disposal cell • SDU structure shall be able to withstand hydrostatic head created by internal liquids • Prevent rain or ground water infiltration • The disposition of a the total Saltstone volume must fit within the permitted boundary of the SDF b. Schedule The required SDU disposal volume is directly tied to the amount of salt waste processing performed by the LW system. Once SDU 6 is filled with Saltstone, the estimated yearly volume of generated Saltstone is expected to be is almost 15Mgal a year. The total estimated volume of Saltstone needed to complete the LW mission is about 200Mgal. Current forecast indicate that SDU 6 will be filled mid fiscal year (FY) 2020. Therefore, the next disposal cell or cells needs to be operational well before this time since the BOP takes about a year to complete after the disposal cell achieves its acceptance testing. 3.0 Requested Information 3.1 DOE is seeking The Department is seeking the following information to support its evaluation of the most cost effective SSC to safety contain and disposition Saltstone within aforementioned constraints. The specific information sought includes:  Recommend SSC(s) to contain and disposition Saltstone which includes  Total cost (rough order of magnitude) - From design, site preparation, to construction completion  Time frame  Optimal disposal cell volume  Recommended strategy for the life-cycle containment of Saltstone  Other recommendations 1.
