This report presents the results from an irradiation test performed on four specimens of grout that were fabricated from synthetic Double Shell Slurry Feed (DSSF) liquid waste. The objective was to investigate the radiolytic generation of gases and the potential for advective rejection of waste liquids from the grout matrix and to provide experimental information for the validation of the C-Cubed calculated model. It has been demonstrated that a number of gases can be formed within the grout due to radiolytic decomposition of various chemical components that make up the grout. This observation leads to the conjecture that the potential exists for the rejection of a portion of the 60 vol% free liquid from the grout matrix driven by pressurization by these gases. It was found that, for the specimen geometries used in this test series, and for peak radiation dose accumulation rates on the order of 4 to 60 times of the initial rate expected in the grout vaults (300 Rads/hr), no liquid rejection was observed from 2% to 35% of the target exposure expected in the grout vaults (1E+08 Rads). When the irradiation rate exceeded the projected grout vault dose rate by a factor of 200 a small …

This report documents a thermal model of tank 241-SY-101 and the surrounding soil column that was used to predict tank temperatures resulting from heating of the annulus ventilation air. Transient results from the model were input to a structural model of the tank for evaluation of the annulus heat-up event.

In the AGS to RHIC transfer line beam profile monitors employing phosphor screens will be used to measure two dimensional beam profile and derive the beam emittance and Twiss parameters. This note present the details as well as summarizes the planned analysis.

Lawrence Livermore National Laboratory`s (LLNL) 4 tonne-per-day oil shale Pilot Retort (4TU-Pilot) has been modeled to study the degree of carbonate decomposition occurring in the process. The modeling uses a simplified version of the processes occurring in the retort to allow parametric studies to be performed. The primary focus of the work is on the sensitivity of computed carbonate decomposition to the assumed manner in which solid material leaves the retort. It was found that for a variety of assumptions about solid passage and evolution within the process the computed carbonate decomposition varied by only a few percent. It was also determined that using available kinetic expressions based on literature data led to a consistent underestimate of the carbonate decomposition, from 12--17% low on an absolute basis and on a relative basis as much as a factor of seven times too low. A simplified kinetic expression based on limited data from laboratory experiments on the same shale as used in the 4TU-Pilot run was also employed and found to match the pilot results fairly well.

The Accelerator-Based Conversion (ABC) facility will be designed to accomplish the following mission: `Provide a weapon`s grade plutonium disposition capability in a safe, economical, and environmentally sound manner on a prudent schedule for [50] tons of weapon`s grade plutonium to be disposed on in [20] years.` This mission is supported by four major objectives: provide a reliable plutonium disposition capability within the next [15] years; provide a level of safety and of safety assurance that meets or exceeds that afforded to the public by modern commercial nuclear power plants; meet or exceed all applicable federal, state, and local regulations or standards for environmental compliance; manage the program in a cost effective manner. The ABC Technology Development Program defines the technology development activities that are required to accomplish this mission. The technology development tasks are related to the following topics: blanket system; vessel systems; reactivity control systems; heat transport system components; energy conversion systems; shutdown heat transport systems components; auxiliary systems; technology demonstrations - large scale experiments.
