Abstract: PURPOSE:To deposit a thin film having a prescribed refractive index on a material for vapor deposition, by detecting reflectivity from a thin film deposited by evaporation on monitor glass and controlling the refractive index from the detected reflectivity. CONSTITUTION:The thin films are respectively formed by vapor deposition on the respective surface of the material 13 for vapor deposition, monitor glass 12 and thick film sensor 15 in a chamber 10. The thickness of the thin film deposited by evaporation on the sensor 15 is detected by a detector 15 and a power supply 25 is controlled from the difference between the vapor deposition speed thereof and a set value. The detected thickness is also inputted to a microprocessor 60.

Inventor: BESSHO TAISUKE
IPC: G21C3/30
Filed: 1988-01-29
Abstract: PURPOSE:To obtain a nuclear reactor which can effectively realize a spectrum shift operation, by providing fuel assemblies with void control elements which can narrowly change a void ratio for the beginning half of a fuel life and with other void control elements which can widely change for the ending half of a fuel life, for a change of coolant flow rate. CONSTITUTION:There is no obstacle in a coolant riser 102' and a coolant downcomer 103' of a void control element 101' used in a fuel assembly 8' for the ending half of a fuel life. Therefore, when a coolant flow rate is increased from 75% to 120% at an ending period of an operational cycle, an average void ratio in the element 101' widely changes from 70% to 0%. On the other hand, because of a large pressure loss of a void control element 101 in a fuel assembly 8 at an orifice 106 of a riser 102, a pressure loss rate by an average void ratio change, decreases in the element 101. Therewith, even if a coolant flow rate is increased from 75% to 120% at an ending period of the operating cycle, the average void ratio in the element 101 changes only by 20%, that is, from 90% to 70%.
