Reactor service life extension program

Description: A review of the Savannah River Site production reactor systems was initiated in 1980 and led to implementation of the Reactor Materials Program in 1984 to assess reactor safety and reactor service life. The program evaluated performance of the reactor tanks, primary coolant piping, and thermal shields, components of welded construction that were fabricated from Type 304 stainless steel. The structural integrity analysis of the primary coolant system has shown that the pressure boundary is not s… more

Praise enhancements to include general strain hardening exponents and mid-life residual stress and water chemistry changes

Description: The purpose of this document is to describe some recent changes made to the PRAISE Code to provide some additional capabilities. The major changes are associated with the new capability to analyze cases where there is a mid-life change in residual stresses and/or water chemistry. Such changes have been proposed as a means of improving the reliability of BWR piping by reducing the oxygen content of the coolant (or other favorable chemistry changes) or altering the residual stresses near welds to… more

Stress Corrosion Cracking of Candidate Structural Materials Under Simulated First-Wall/Aqueous Coolant Environments

Description: Stress corrosion cracking (SCC) susceptibility of Types 316NG, 316, and 304 stainless steels (SS) was investigated in slow-strain-rate tests (SSRTs) in oxygenated water that simulates important parameters anticipated in first-wall/blanket systems. The water chemistry was based on a computer code which yielded the nominal concentrations of radiolytic species produced in an aqueous environment under ITER-type conditions. Actual SSRTs were performed in a less benign, more oxidizing reference envir… more

Compliance of the Savannah River Site D-Area cooling system with environmental regulations

Description: This document presents information relating to a demonstration under Section 316(a) of the Clean Water Act for the 400-D Area cooling system at the Savannah River Site (SRS) near Aiken, South Carolina. The demonstration was mandated because the National Pollution Discharge Elimination System (NPDES) permit for SRS (SC0000175), granted on January 1, 1984, specified in-stream temperature limits in SRS streams of 32.2{degree}C and a {Delta}T limit of 2.8{degree}C above ambient. To achieve complian… more

Environmentally assisted cracking in light water reactors

Description: Topics that have been investigated during this year include (1) SCC of A533-Gr B steel used in steam generator and reactor pressure vessels, (2) fatigue of Type 316NG SS, and (3) SCC of Type 347 and CF-3 cast duplex stainless steels in simulated BWR water. Crack-growth-rate (CGR) tests were performed on a composite A533-Gr B/Inconel-182 specimen in which the stress corrosion crack in the Inconel-182 weld metal penetrated and grew into the A533-Gr B steel. CGR tests were also conducted on conven… more

Adirondack Lakes Survey: An Interpretive Analysis of Fish Communities and Water Chemistry, 1984--1987

Description: The Adirondack Lakes Survey Corporation (ALSC) was formed as a cooperative effort of the New York State Department of Environmental Conservation and the Empire State Electric Energy Research Corporation to better characterize the chemical and biological status of Adirondack lakes. Between 1984 and 1987, the ALSC surveyed 1469 lakes within the Adirondack ecological zone. As a follow-up to the survey, the ALSC sponsored a series of interpretive analyses of the ALSC data base. The primary objectiv… more

Assessment of tree toxicity near the F- and H-Area seepage basins of the Savannah River Site

Description: Areas of tree mortality, originating in 1979, have been documented downslope of the F- and H-Area Seepage Basins. The basins were used as discharge areas for low-level radioactive and nonradioactive waste. Preliminary studies indicated that there are three possible causes of stress: altered hydrology; hazardous chemicals; and nonhazardous chemicals. It was originally hypothesized that the most likely hydrological stressors to Nyssa sylvatica var. biflora were flooding where water levels cover t… more

Evaluation of available saline water resources in New Mexico for the production of microalgae

Description: Researchers evaluated saline water resources in New Mexico for their suitability as sites for large-scale microalgae production facilities. Production of microalgae could provide a renewable source of fuel, chemicals, and food. In addition, making use of the unused saline water resources would increase the economic activity in the state. After analyzing the 15 billion acre-ft of unused saline water resources in the state, scientists narrowed the locations down to six sites with the most potenti… more

Geothermal fluid genesis in the Great Basin

Description: Early theories concerning geothermal recharge in the Great Basin implied recharge was by recent precipitation. Physical, chemical, and isotopic differences between thermal and non-thermal fluids and global paleoclimatic indicators suggest that recharge occurred during the late Pleistocene. Polar region isotopic studies demonstrate that a depletion in stable light-isotopes of precipitation existed during the late Pleistocene due to the colder, wetter climate. Isotopic analysis of calcite veins a… more

Corrosion of copper in Mound's single-pass potable water systems

Description: An increase in the number of copper plumbing failures at Mound prompted a thorough analysis of the failed components. Most of the components were elbow joints. All of these parts exhibited the same type of accelerated deterioration. The failed parts were analyzed optically and by scanning electron microscopy. Water chemistry, solder, and soldering fluxes were evaluated to determine their possible roles in the accelerated attack. Cross-sectioning of the elbow joints revealed residual soldering f… more

Recovery of contaminated wetland soils at the Savannah River Site by natural rainfall: An experimental, toxicological study

Description: This study was conducted at the Department of Energy Savannah River Site in South Carolina. Seepage basins at the SRS F-Area received liquid effluent from the 1950s to 1988. This effluent was typically acidic, containing high amounts of total dissolved ions, low levels of tritium and other radioactive elements, and trace levels of various heavy metals. Sodium (from NaOH), and aluminum (from soil matrix reduction due to acid leachate) were at particularly high levels in the outcropping water. Th… more

Bacterially induced precipitation of CaCO{sub 3}: An example from studies of cyanobacterial mats. Final report

Description: Bacteria induce the precipitation of calcium carbonate in the laboratory and in nature by altering their chemical environment. Geologists are recognizing the possibility that bacterially induced precipitates may form significant mineral deposits, unfortunately, there are currently no sound criteria by which they can be recognized in recent sediments, or in the rock record. Cultures of aerobic and facultative bacteria from cyanobacterial mats on Andros Island, Bahamas, and Baffin Bay, Texas, ind… more
