Download Tritium Processing at the Savannah River Site (SRS) Book in PDF, ePub and Kindle
Tritium handling equipment and methods at the Savannah River Site Tritium Facilities have been continually improved since tritium processing operations began in 1955. Several new technologies were introduced into the Tritium Facilities in the 1980's. One of these is the use of fluidless, mechanical pumps (Normetex and Metal Bellows) to replace mercury pumps. A second is the use of metal hydride technology to store, purify, isotopically separate, pump, and compress hydrogen isotopes. Metal hydrides, such as La-Ni-Al alloys and Pd loaded on kieselguhr, offer significant flexibility and size advantages compared with conventional tritium handling technology, such as gas tanks, thermal diffusion columns, and mechanical compressors. Metal hydrides have been used in the Tritium Facilities since 1984 with the most important application of this technology being planned for the Replacement Tritium Facility, a $140 million facility scheduled for completion in 1990 and startup in 1991. 11 refs., 9 figs.

Download Startup Status of the Replacement Tritium Facility at the Savannah River Site Book in PDF, ePub and Kindle
Tritium processing operations have been performed at the Savannah River Site (SRS) since 1955. It was determined in the early 1980's that new tritium facilities were required in order to meet increasingly stringent safety and environmental requirements while maintaining productivity. Construction of a new tritium handling facility, the Replacement Tritium Facility (RTF), began in 1987. This new facility incorporates the latest technology and design philosophy to mitigate accident consequences, enhance operational safety, minimize tritium losses to the environment, and ensure material safeguards and security. The RTF is currently completing startup operations. This report details key features addressed during the design and startup of this facility.

Download Tritium Confinement in a New Tritium Processing Facility at the Savannah River Site Book in PDF, ePub and Kindle
A new tritium processing facility, named the Replacement Tritium Facility (RTF), has been completed and is being prepared for startup at the Savannah River Site (SRS). The RTF has the capability to recover, purify and separate hydrogen isotopes from recycled gas containers. A multilayered confinement system is designed to reduce tritium losses to the environment. This confinement system is expected to confine and recover any tritium that might escape the process equipment, and to maintain the tritium concentration in the nitrogen glovebox atmosphere to less than 10−2 [mu]Ci/cc tritium.

Download NEW SYSTEMS FOR WASTE PROCESSING OF TRITIUM-CONTAINING GASESAT THE SAVANNAH RIVER SITE. Book in PDF, ePub and Kindle
A project to relocate and consolidate tritium processing activities from old, second generation buildings to newer buildings was initiated in the late 1990's at the Savannah River Site (SRS). This project replaces two existing gaseous process waste treatment systems currently operating in an older facility. The new waste gas processing systems located in the newer facility use recent technology, including metal getters, an innovative permeator design, and TCAP--Thermal Cycling Absorption Process--technology for removal of residual tritium prior to releasing the effluent to the environment. Startup testing results and corresponding lessons learned for these systems are presented. These systems have successfully completed startup testing and are operational.

Download Transporter Development for the Tritium Extraction Facility at the Savannah River Site Book in PDF, ePub and Kindle
The Commercial Light Water Reactor-Tritium Extraction Facility (CLWR-TEF) is planned for location at the Savannah River Site (SRS) as part of the US Department of Energy CLWR tritium production alternative. This new facility will rely on processes and equipment that are significantly different from those proven in the past or currently in use at SRS. For instance, the CLWR-TEF reference design employs remote modules to provide an inert processing atmosphere, secondary confinement for tritium and the primary confinement for particulate contamination. The primary component of this modular system is the Transporter. A Transporter mock-up was developed to demonstrate concept feasibility of the required processing functions (sealing, attachment/alignment and materials handling). The module design, the seal door selection, and the planned test program are discussed.

Download Alternatives for High-Level Waste Salt Processing at the Savannah River Site Book in PDF, ePub and Kindle
The Second World War introduced the world to nuclear weapons and their consequences. Behind the scene of these nuclear weapons and an aspect of their consequences is radioactive waste. Radioactive waste has varying degrees of harmfulness and poses a problem when it comes to storage and disposal. Radioactive waste is usually kept below ground in varying containers, which depend on how radioactive the waste it. High-level radioactive waste (HLW) can be stored in underground carbon-steel tanks. However, radioactive waste must also be further immobilized to ensure our safety. There are several sites in the United States where high-level radioactive waste (HLW) are stored; including the Savannah River Site (SRS), established in 1950 to produce plutonium and tritium isotopes for defense purposes. In order to further immobilize the radioactive waste at this site an in-tank precipitation (ITP) process is utilized. Through this method, the sludge portion of the tank wastes is being removed and immobilized in borosilicate glass for eventual disposal in a geological repository. As a result, a highly alkaline salt, present in both liquid and solid forms, is produced. The salt contains cesium, strontium, actinides such as plutonium and neptunium, and other radionuclides. But is this the best method? The National Research Council (NRC) has empanelled a committee, at the request of the U.S. Department of Energy (DOE), to provide an independent technical review of alternatives to the discontinued in-tank precipitation (ITP) process for treating the HLW stored in tanks at the SRS. Alternatives for High-Level Waste Salt Processing at the Savannah RIver Site summarizes the finding of the committee which sought to answer 4 questions including: "Was an appropriately comprehensive set of cesium partitioning alternatives identified and are there other alternatives that should be explored?" and "Are there significant barriers to the implementation of any of the preferred alternatives, taking into account their state of development and their ability to be integrated into the existing SRS HLW system?"
