Abstract: An electrochemically active hydrogen diffusion barrier which comprises an anode layer, a cathode layer, and an intermediate electrolyte layer, which is conductive to protons and substantially impermeable to hydrogen. A catalytic metal present in or adjacent to the anode layer catalyzes an electrochemical reaction that converts any hydrogen that diffuses through the electrolyte layer to protons and electrons. The protons and electrons are transported to the cathode layer and reacted to form hydrogen. The hydrogen diffusion barrier is applied to a polymeric substrate used in a storage tank to store hydrogen under high pressure. A storage tank equipped with the electrochemically active hydrogen diffusion barrier, a method of fabricating the storage tank, and a method of preventing hydrogen from diffusing out of a storage tank are also disclosed.

Abstract: A composition for use as a radiation shield. The shield is a concrete product containing a stable uranium aggregate for attenuating gamma rays and a neutron absorbing component, the uranium aggregate and neutron absorbing component being present in the concrete product in sufficient amounts to provide a concrete having a density between about 4 and about 15 grams/cm.sup.3 and which will at a predetermined thickness, attenuate gamma rays and absorb neutrons from a radioactive material of projected gamma ray and neutron emissions over a determined time period. The composition is preferably in the form of a container for storing radioactive materials that emit gamma rays and neutrons. The concrete container preferably comprises a metal liner and/or a metal outer shell. The resulting radiation shielding container has the potential of being structurally sound, stable over a long period of time, and, if desired, readily mobile.

Abstract: A process for manufacturing Si.sub.3 N.sub.4 /SiAlON whiskers by mixing silicon carbide powder with aluminum nitride powder, adding impurities such as calcium oxide or potassium chloride to control whisker characteristics, forming the mixture in a boron nitrogen mold of desired shaped and hot isostatically pressing the formed mixture in a nitrogen environment to produce whiskers comprised substantially of SiAlON at the nucleating end of the whisker and Si.sub.3 N.sub.4 at the other end of the whisker. In one embodiment, reinforced composites are formed by impregnating the Si.sub.3 N.sub.4 /SiAlON whisker preform with a matrix material such as resin binders, liquid metals, intermetallics or ceramic materials.

Abstract: An accurate method for testing the strength of nuclear fuel particles. Each particle includes an upper and lower portion, and is placed within a testing apparatus having upper and lower compression members. The upper compression member includes a depression therein which is circular and sized to receive only part of the upper portion of the particle. The lower compression member also includes a similar depression. The compression members are parallel to each other with the depressions therein being axially aligned. The fuel particle is then placed between the compression members and engaged within the depressions. The particle is then compressed between the compression members until it fractures. The amount of force needed to fracture the particle is thereafter recorded. This technique allows a broader distribution of forces and provides more accurate results compared with systems which distribute forces at singular points on the particle. 05459767621 00000000000000000460000000000000000000000000000000000000000000000000000000000098

Abstract translation: 一种用于测试核燃料颗粒强度的准确方法。 每个颗粒包括上部和下部，并且放置在具有上部和下部压缩构件的测试装置内。 上部压缩构件包括其中的凹部，其为圆形并且尺寸仅仅接收颗粒的上部的一部分。 下压缩构件还包括类似的凹陷。 压缩构件彼此平行，其中的凹部被轴向对准。 然后将燃料颗粒放置在压缩构件之间并且接合在凹陷中。 然后将颗粒压缩在压缩构件之间直到其断裂。 此后记录破碎颗粒所需的力量。 与在颗粒上的单个点分布力的系统相比，该技术允许更广泛的力分布并提供更准确的结果。
