... Hydride precipitation may impact the integrity of zirconium-based nuclear fuel cladding, both during normal operation and during extended dry storage. To better understand such degradation, a study of hydride precipitation of zirconium hydrides in Zircaloy-4 samples was performed. The samples...

... graphites showing the least specimen volume/diameter effect. Here the volume dependency trends are discussed in terms of the graphite’s filler-particle size and texture. graphite carbon nuclear physical properties GRAPHITE TESTING FOR NUCLEAR APPLICATIONS: THE SIGNIFICANCE OF TEST SPECIMEN...

... This paper describes a comparative study of the three most commonly used field density tests: sand-cone, nuclear, and drive-cylinder. In order to evaluate the range of variability of these tests, a large-scale soil compaction apparatus was constructed so that soil could be compacted to a known...

... Transport flasks are required for the movement of spent nuclear fuel. Due to their nature of operation, it is necessary that these flasks are produced from forged steels with exceptional toughness properties. The material specification generally cited for flask manufacture is ASTM A350 Grade LF5...

... The comfort properties of newly developed 100% nylon and 100% polyester fabrics are compared with materials that are currently used in nuclear protective apparel, including a 100% cotton and a polyester/cotton fabric. The Kawabata Evaluation System provided a highly sensitive measure of fabric...

... Fasteners used in operating nuclear power plants are subjected to specific design rules. The regulatory basis for these rules is contained in Part 50 of Title 10 of the Code of Federal Regulations (10 CFR Part 50). The Code specifies that safety-related components in an operating nuclear power...

... The Materials Dosimetry Reference Facility (MDRF) is a new reactor-driven reference neutron field for reactor dosimetry calibrations and methods validation. Basically, the facility design is a steel cylinder (15-cm o.d., 5-cm i.d.) mounted in the pool close to the core of the Ford Nuclear...

... Acceptance sampling of incoming items is a common activity conducted by purchasers in many different industries. In the commercial nuclear industry, procurements of replacement parts for operating plants typically involve small quantities purchased in isolated lots. This paper discusses a newly...

.... The D9 transient and mechanical properties data are now available for computer code analysis of D9 as a fast reactor fuel system material. radiation irradiation nuclear fuel cladding fast fluence transient mechanical properties tensile fracture toughness strength ductility D9 N. Scott...

... The decade of the 1980s saw the identification of many adverse chemistry conditions that, when recognized, resulted in dramatic improvement in water quality in the primary and secondary systems of nuclear power plants. Many of the chemistry program upgrades resulted from the need to improve...

... The feasibility of many old and new technologies that can be used in determining pavement condition have been investigated. These technologies include image processing, electromagnetic waves, nuclear, laser, spin-up/spin-down, eddy current, and ultrasonic waves. Various equipment in use...

... The fact that buried metallic structures corrode is well documented. It has been postulated that the extent and rate of attack is controlled predominantly by the characteristics of the surrounding soil. Therefore, prior to constructing a new facility designed to process accumulated nuclear waste...

... Westinghouse has been conducting a program to upgrade the purity of primary-loop cooling water in pressurized water reactor (PWR) nuclear power plants, and a method was needed to measure cationic impurities such as calcium, magnesium, and aluminum in the 0 to 10-ppb range. After examination...
