Prior to entombment, the nuclear facility permanently ceases operations and spent fuel is removed. After preliminary decommissioning activities are completed, some radioactively contaminated components would be left in an existing structure on the site. The radioactive materials are then entombed with an engineered barrier system that could include filling the structure with a grout or infill. In the process, various construction issues must be addressed to assure the desired facility performance. The NRC has asked NIST to coordinate a preliminary overview of the needs specific to cementitious grouts. Cementitious grouts are a viable candidate for entombment because they may provide both a physical and a chemical barrier to radionuclide transport. The difficulties in using cementitious grouts are the potential materials selection, material properties, and constructability issues that might arise. Depending upon the entombment scenario, the design may require the grout to completely fill all the available space. To achieve this, the grout must have certain rheological properties that will likely require adding chemical admixtures that may interfere with other grout properties. In addition, other desirable material properties might require increased cement contents. Unfortunately, increasing the cement content can lead to heat production issues that may affect overall constructibility. Moreover, although each of these issues has been addressed individually, achieving all these requirements simultaneously will require careful materials selection and proportioning. This work will be performed as part of a larger project that includes NIST personnel and other contractors. Other groups will be working on separate issues regarding the use of grouts: rheology, radionuclide leaching, modeling and testing. Although separate tasks, each must be performed in collaboration with others working on the project. Purpose and Objectives- The primary purpose of the overall project is the creation of guidelines for materials selection and use of cementitious grouts. This subcontract shall address all the following topics as they relate to this purpose: Materials Selection: proportioning guidelines and testing protocols. Cement Interactions: radionuclides and heavy metal. Material Properties: diffusivity, permeability, pH, and Eh. 1 Constructibility: placement, setting characteristics, curing, heat production and dissipation, volume changes, and monitoring. Design Criteria: design life, structural integrity, long-term warnings. Relevant Projects: examples and summaries. Work Requirement- Task 1: Analysis, and Summary: The contractor shall enumerate and describe in detail construction issues that may arise in the use of a cementitious grout in the entombment of a nuclear concrete structure. These issues, listed in the Purpose and Objectives section, include, but are not limited to, materials selection, mixing, transport, heat production, and mechanical stability. These issues shall be addressed in the context of achieving an overall entombment design goal. (The issue of grout rheology will be addressed by NIST personnel.) The contractor shall discuss relevant construction projects that have employed cementitious grouts in the entombment of nuclear concrete structures. The contractor shall discuss the most advanced field knowledge on the selection of materials for the grouts. The materials considered shall include both supplemental pozzolanic materials and chemical admixtures. The contractor shall discuss available tools and guidelines for the selection of these materials. Task 2: Reporting Results- The contractor shall summarize the findings in Task 1 into a report that will be incorporated into the final report. The contractor is expected to collaborate on the final document assembly. 2 Travel- NIST will pay travel expenses for contractor travel to NIST for periodic meetings with the entire project staff, in accordance with Government-allowable rates and prior approval by the Technical Contact and the Contracting Officer. The contractor shall budget for anticipated travel expenses to one nuclear facility, at a location not determined, within the continental United States. NIST will accept travel cost invoices for pre-approved travel at allowable rates, on a as needed basis. Deliverables: extended outline for final report; final report. Expected Effort-NIST expects the total effort for Task 1 and Task 2 combined to be less than 2 man-months. Timetable-The contractor shall complete Task 2 prior to Aug 1, 2004.*****Vendors/parties shall submit response, to National Institute of Standards and Technology, ATTN Tamara Grinspon, Acquisition and Logistics Division/Contracts, 100 Bureau Drive?STOP 3571, Gaithersburg, MD 20899-3571, via email (tamara.grinspon@nist.gov )AND facsimile (FAX: (301) 975-6273) on or before 3:00PM EST, April 5, 2004.
