Latest Patents
Tsunashima holds 1 patent for his invention titled "Reactor in-vessel sensor and core monitoring apparatus." This sensor is designed to monitor the interior of a sodium-cooled fast breeder reactor. It comprises a pair of symmetrical magnetic cores, a magnetostrictive or piezoelectric vibrator element bonded to one of the cores, a primary coil, and a plurality of secondary coils surrounding the magnetic cores. The primary coil, when applied with an exciting alternating current, generates an acoustic signal voltage indicative of any sound originating in the reactor's interior. The magnetic flux produced by the exciting current is influenced by the temperature and flow velocity of sodium flowing around the sensor, resulting in corresponding voltage signals induced in the secondary coils.
