IPC: G21C17/07
Filed: 1989-11-16
Abstract: PURPOSE:To confirm water level by putting part of a shipper cap below the gap of the upper grating plate of a fuel assembly and discharging air when the water level falls below an air by-pass hole bored in the entrance part. CONSTITUTION:A projection part 12 to be inserted between fuel assemblies 1 is formed at the lower end part of the shipper cap 20 and the air by-pass hole 13 is bored in the projection part 12. The size of the projection part 12 is so determined that the projection part can enter the gap part 13 between the assemblies 1. In this constitution, when the water level is raised above the upper end of the assembly 1, the air is discharged from the shipper cap 20 even if the water level is below the upper end of the upper grating plate 10, so that the water level of the cooling water in the shipper cap 20 can be confirmed from air bubbles.

Title: Emission spectrophotometer
Inventor: ASADA SHOTARO
IPC: G01N21/62
Filed: 1990-10-31
Abstract: PURPOSE:To prevent dispersion in detecting sensitivity by storing the current values of the detected signals based on the emission of light from a sample, and controlling voltages to be applied so that the current value obtained by receiving the light of a fatigue lamp agrees with the stored value. CONSTITUTION:When light is emitted from a sample by spark discharge and the like, the light is reflected from a reflecting mirror 4a and cast on a grating 4b. The light is dispersed into spectral lights. The lights are received with photomultiplier tubes 6a - 6n, respectively. A CPU 14 applies specified voltages into the photomultiplier tubes 6a - 6n so as to obtain the desired sensitivities. The detected signals having the current values corresponding to the intensities of the spectral lights are outputted and digitized in A/D converters 10a - 10b. Thereafter the results are stored in a memory 12. Then, the CPU 14 stops the light emission of the sample and lights up a fatigue lamp 8. The signals corresponding to the amount of the light from the lamp 8 are outputted from the photomultiplier tubes 6a - 6n and received with the A/D converters 10a - 10n. The voltages applied on the photomultiplier tubes 6a - 6n are controlled so that the voltages agree with the stored values in the memory 12. Therefore, the response of the photomultiplier tubes 6a - 6n is quick in the sample analysis, and dispersion in sensitivity does not occur.
