“…44 An American judge encapsulates the rationale of sex as condonation neatly when he states, "[T]his court does not feel that parties should be allowed to maintain sexual relations and at the same time seek a divorce as the two acts are completely incompatible." 45 In effect, condonation works like this: if a woman were to discover that her husband had been having an affair, the wife could petition for divorce on those grounds. If, however, at any time between her discovery of her husband's adultery and the case being decided in court, the wife were to have sex voluntarily with her husband, she would be said to have condoned her husband's adultery-that is, to have forgiven him the offense and to have reinstated him as her husband.…”

“…Metal hydrides have historically been produced using a Sievert's apparatus, which is a gas manifold attached to a reaction vessel maintained at a temperature of interest [2]. A metal sample is placed in the reaction vessel and hydrogen is titrated into the vessel in very well-defined aliquots.…”

“…The latter could be detrimental for reliable reactor operation, and thus the use of hydrided zirconium is limited to lower-temperature applications. Yttrium dihydride had been tested as a higher temperature moderator during the 1960s as part of the aircraft propulsion project [2], [9], [12], [29]. Yttrium dihydride was studied, but never fully developed for use in a working reactor system.…”

High hydrogen density moderators such as metal hydrides are an important research topic within the DOE NE Microreactor Research, Development, and Deployment (RD&D) Program due to their ability to retain hydrogen to much higher temperatures than other hydrogenous media. This class of moderators, which includes yttrium dihydride (YH2), thermalizes neutrons in the system such that the overall fuel mass or the required uranium enrichment in the system can be significantly reduced. Knowledge of material properties, both in the as-fabricated and irradiated state, are important to understanding moderator performance during steady-state and transient reactor operation. Provided in this document is the Advanced Moderator Material Handbook, which provides a detailed summary of the literature data on yttrium dihydride, thermomechanical and other property data, and a critical evaluation of that data. This handbook also provides a description of ongoing experiments to understand in-reactor performance, such as irradiations in ATR, as well as nuclear data from an integral critical experiment at NCERC. The majority of this report focuses on measured values but also includes some modeling results for comparison where applicable.

“…There is renewed interest in using hightemperature metal hydrides (HTMHs) that operate between 600 °C and 800 °C as low-cost, high-density thermal energy storage (TES) materials [1][2][3][4][5] for use with next-generation Concentrating Solar Power (CSP) [6]. However, metal hydrides with high thermodynamic stability have potential use in a wide range of other practical applications related to permanent magnets [7,8], switchable mirrors [9], powder processing [10][11][12] and moderator or shielding components for nuclear reactors [13,14]. A critical step in assessing the potential of any metal hydride candidate is the accurate evaluation of its thermodynamic and kinetic properties utilising pressure-composition-isotherms (PCIs) measurements.…”
