Title (EN) HYDROGEN CONCENTRATION MEASURING INSTRUMENT, AND CONTROL SYSTEM
(FR) INSTRUMENT DE MESURE DE CONCENTRATION EN HYDROGÈNE ET SYSTÈME DE COMMANDE
(JA) 水素濃度計測器および制御システム
Abstract:
(EN)  In one embodiment, a hydrogen concentration measuring instrument (10) for measuring the hydrogen concentration of the atmosphere in a containment vessel is equipped with: a solid electrolyte (12) for generating electromotive force according to the hydrogen concentration of the atmosphere; a heating unit (16) for maintaining the temperature of the solid electrolyte (12) at a higher temperature than the temperature that the hydrogen concentration measuring instrument (10) can achieve when an accident occurs in the containment vessel; and a voltmeter (15) for detecting the magnitude of the electromotive force generated by the solid electrolyte (12).
(FR) L'invention concerne, dans un mode de réalisation, un instrument de mesure de concentration en hydrogène (10) pour mesurer la concentration en hydrogène de l'atmosphère dans un récipient de confinement qui comporte : un électrolyte solide (12) pour générer une force électromotrice selon la concentration en hydrogène de l'atmosphère ; une unité chauffante (16) pour maintenir la température de l'électrolyte solide (12) à une température plus élevée que la température que l'instrument de mesure de concentration en hydrogène (10) peut atteindre lorsqu'un accident se produit dans le récipient de confinement ; et un voltmètre (15) pour détecter l'amplitude de la force électromotrice générée par l'électrolyte solide (12).
(JA)  1つの態様において、原子炉格納容器内の雰囲気の水素濃度を計測する水素濃度計測器10は、雰囲気の水素濃度に応じて起電力を発生する固体電解質12と、固体電解質12の温度を、原子炉格納容器内で事故が発生した場合に水素濃度計測器10が到達しうる温度よりも高い温度に保つ加熱部16と、固体電解質12が発生する起電力の大きさを検出する電圧計15とを備える。
