Main Operating Conditions That Can Influence the Evolution of Wines during Long-Term Storage

Drum type packages are routinely used to transport radioactive material (RAM) in the U.S. Department of Energy (DOE) complex. These packages are designed to meet the federal regulations described in 10 CFR 71. In recent years, there has been a greater need to use these packagings to store the excess fissile material, especially plutonium for long term storage. While the design requirements for safe transportation of these packagings are well defined, the requirements for safe long term storage are not well established. Since the RAM contents in the packagings produce decay heat, it is important that they are stored carefully to prevent overheating of the containment vessel (CV) seals to prevent any leakage and the impact limiter to maintain the package structural integrity. This paper analyzes different storage arrays for a typical 9977 packaging for thermal considerations and makes recommendations for their safe storage under normal operating conditions.

Abstract Electronics density continue to increase which impacts the power density and thermal hot spots on the printed circuit boards. The reliability and prediction of the electronics failure rate is often related to the thermal stress induced during different operating conditions at the board. To get information about the environmental conditions and to assist in the prediction of a product's failure rate a monitoring system could be used. This paper presents a temperature monitoring function implemented in an FPGA using VHDL. The proposed system is composed of a number of temperature sensors together with a non-volatile MRAM memory for long-term storage. The solution offers a flexible system that could be scaled to an arbitrary number of sensors and be adapted to any FPGA or processor technology. To verify the concept, a climate chamber was used to simulate a number of different environmental settings followed by a reading of the data logged.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.
