Title: Fast breeder reactor
Inventor: HASHIGUCHI SADAO
IPC: G21D1/02
Filed: 1990-11-30
Abstract: PURPOSE:To contrive improvement of safety by providing a cover gas part in a nuclear reactor vessel and a connecting pipe among the sealing gaps and also a pressure relief valve, by which pressure difference between the cover gas pressure and pressure of sealing gaps can be mitigated, during emergent shut-down of the reactor. CONSTITUTION:When an abnormality accompanied with isolation of a containment vessel 58 occurs, containment isolation valves 47 to 50 of an Argon gas piping system 51 penetrating through the vessel 58, are immediately shut off, the cover gas 44 becomes of a sealed-off condition and thereby the nuclear reactor is shut down. In case that the gas at sealing gaps 46 is pressurized abnormally high, temperature of a sodium 43 lowers gradually and contracts and therewith the gas 44 pressure becomes exceedingly negative to the pressure at the gaps 46, and pressure difference appears there. At this moment, pressure relief valves 55a and 55b of the connecting pipe 54 between the gas 44 and the gaps 46, are opened and thereby excess external-pressure working on the nuclear reactor vessel 1 can be avoided. Also, since the valves 55a and 55b are arranged in parallel, the function can be maintained even though one of them fails. In this way, safety and economy thereof can be well improved.

IPC: G01B11/00
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To surely measure height position of a sample surface, regardless of the inclination of the sample surface. SOLUTION: An incident light axis of a photoirradiation optical system is, under the condition that it is in three-dimensional space of x, y and z and doesn't pass through the y-axis and the x-y plane, set/adjusted into the y-z plane for inclining. A detecting optical system is optical-designed so that its optical center (to be concrete, lens center) is in accord with a reflected light optical axis (reflection angle is θy) at sample surface inclination angle θy/2, for detecting the reflected light reflected on the sample surface (the reflection angle is 2θy<180 deg.) with the detecting optical system. The light from a light source is set/adjusted into the y-z plane, and made incident to the x-y plane for inclining by α deg.. When θy changes in the range of 0<=θy<90 deg., the numerical aperture (N.A.) is in 0<=N.A.<1. By this constitution even when the sample surface inclines in the range of 0<=θy<90 deg., position detection in z-direction of the sample surface (focus detection) is enabled.
