Some deficiencies in analyzing leachates and reporting results

Description: Determination of the leachability of elements from various radioactive waste forms for long-term retention requires chemical analysis of both the leachate and waste form. Neither the precision of the leaching procedure nor the accuracy of the results can be determined unambiguously if gross uncertainties exist. It should be demonstrated beforehand that all participating laboratories can obtain the same analytical result within some stated uncertainty. Special precautions must be taken to ensure… more

Barrier Erosion Control Test Plan: Gravel Mulch, Vegetation, and Soil Water Interactions

Description: Soil erosion could reduce the water storage capacity of barriers that have been proposed for the disposal of near-surface waste at the US Department of Energy's Hanford Site. Gravel mixed into the top soil surface may create a self-healing veneer that greatly retards soil loss. However, gravel admixtures may also enhance infiltration of rainwater, suppress plant growth and water extraction, and lead to the leaching of underlying waste. This report describes plans for two experiments that were d… more

Cadmium safety rod thermal tests

Description: Thermal testing of cadmium safety rods was conducted as part of a program to define the response of Savannah River Site (SRS) production reactor core components to a hypothetical LOCA leading to a drained reactor tank. The safety rods are present in the reactor core only during shutdown and are not used as a control mechanism during operation; thus, their response to the conditions predicted for the LOCA is only of interest to the extent that it could impact the progression of the accident.

Fungal degradation of organophosphorous insecticides

Description: Organophosphorous insecticides are used extensively to treat a variety of pests and insects. Although as a group they are easily degraded by bacteria in the environment, a number of them have half-lives of several months. Little is known about their biodegradation by fungi. We have shown that Phanerochaete chrysosporium can substantially degrade chlorpyrifos, fonofos, and terbufos (27.5%, 12.2%, and 26.6%, respectively) during 18-day incubation in nitrogen-limited stationary cultures. The resul… more

Coolability of a control rod which has melted and foamed in its septifoil channel

Description: During a Loss of Control Rod Cooling (LCRC) event, the control rods which are in the affected septifoil can be postulated to melt. Melting of a control rod which has been irradiated creates a special concern since the entrapped gases expand rapidly and cause the melt to manifest itself initially in a foamed state. The foamed material then contacts the septifoil outer housing and the inner septifoil web material, where heat is conducted out of the foamed material. A second concern relating to th… more
