Long Term Corrosion Potential Behavior of Alloy 22 in Yucca Mountain Relevant Environments

Description: The approach of isolating high-level nuclear waste in the designated site of Yucca Mountain (Nevada) is to separate it from the environment using a series of engineering and natural barriers. The container for the waste will consist of two concentric metal cylinders. The outer cylinder is going to be fabricated of Alloy 22 (N06022). If water is present at the site, several corrosion processes may occur. These include passive or general corrosion, localized corrosion and environmentally assisted… more

Manufacture of Large-Aperture Diffractive Optics and Ultrathin Optics for High-Power Laser and Space Applications

Description: We have developed equipment and technology for fabricating submicron pitch, high-efficiency diffraction gratings over meter-scale apertures that are used for pulse compression in ultrafast systems around the world. We have also developed wet-etch figuring (WEF) to generate arbitrary continuous contours on ultrathin glass substrates in a closed loop process. The current and future states of these technologies will be discussed.

Modeling and Prediction Overview

Description: Effective preparation for and response to the release of toxic materials into the atmosphere hinges on accurate predictions of the dispersion pathway, concentration, and ultimate fate of the chemical or biological agent. Of particular interest is the threat to civilian populations within major urban areas, which are likely targets for potential attacks. The goals of the CBNP Modeling and Prediction area are: (1) Development of a suite of validated, multi-scale, atmospheric transport and fate mo… more

Main installation and services. Final report for DOE Grant No. DE-FG02-96CH10859

Description: Early in 1996 it was reported that groundwater contamination in the form of volatile organic chemicals had been found in several private wells in an area immediately adjacent to the Brookhaven National Laboratory (BNL) in Upton, New York. Information released by BNL and their consulting hydrologists indicates that there should be no threat to the Authority's downgradient well fields located in Mastic as a result of said contamination. This is due to the remediation efforts undertaken by BNL at … more

Irradiation of structure material in spallation neutron sources.

Description: In principle, intense spallation neutron sources can be used not only to irradiate materials (e.g. window materials) and to validate different target geometries/concepts, but also to irradiate structural materials (samples, pins or even full assemblies) in order to characterize their behavior under irradiation (in a fast neutron field). However, a question arises concerning the ''representativity'' of such irradiations to reproduce the conditions encountered in a typical fast reactor. The prese… more
