Download INTEGRATED PROCESS GAS MODELING FOR TRITIUM SYSTEMS AT THE SAVANNAH RIVER SITE. Book in PDF, ePub and Kindle
Significant savings are being realized from the consolidated tritium gas-processing operations at the Savannah River Site. However, the trade-off is some reduction of operational flexibility due to decreased storage capacity for process and waste gases. Savannah River National Laboratory researchers are developing an integrated process gas model for tritium processing using Aspen Custom Modeler{trademark} (ACM) software. The modeling involves fully characterizing process flow streams (gas composition, quantity), frequency of batch transfers, and availability of equipment in the flow stream. The model provides a valuable engineering tool to identify flow bottlenecks, thereby enabling adjustments to be made to improve process operations.

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 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 Modeling of Tritium Annual Flux from Concrete Rubble Buried in the Slit Trenches at the Savannah River Site Book in PDF, ePub and Kindle
Some of the concrete rubble generated from the demolition and destruction of some facilities at the U.S. Department of Energy Savannah River Site contains tritium. The tritium-bearing rubble will be disposed in the E-Area slit trenches. In the past, it was assumed for Performance Assessment (risk) modeling that tritium leached from concrete as if the tritium existed entirely on the concrete surfaces. Although conservative (i.e., overestimates risk associated with the groundwater pathway), this assumption does not account for the slow diffusion of tritium from the inside to the outside of the concrete rubble. The objective of this modeling study was to include the diffusion process in tritium annual flux calculations for use in future Special Analyses or Performance Assessments involving the concrete rubble. This paper discusses the general modeling approach and presents the study results.

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.
