Title: Structure of nuclear reactor
Inventor: ITOU TOMOMICHI
IPC: G21C15/247
Filed: 1988-09-12
Abstract: PURPOSE:To prevent occurrence of a temperature layering phenomenon produced in an upper plenum and to eliminate the decay heat produced when a nuclear reactor scrams by providing a small-size pump in the upper plenum of a reactor vessel containing high-temperature Na. CONSTITUTION:At the time of normal rated operations, the fluid spouting out from a reactor core 1 flows in the oblique direction after colliding with the upper mechanism 6 of the reactor and is sucked through the window section of an intermediate heat exchanger 3. The fluid then reaches a cold plenum through the exchanger 3. When the reactor scrams, the heat production of the core 1 is stopped by the insertion of control rods and the fluid spouting out from the core 1 enters the plenum 2 as a cold fluid, since the temperature of the fluid does not rise. Since the cold fluid stays on the bottom of the plenum 2, a temperature layering phenomenon gradually takes place. When a small-size pump for forced circulation provided in the plenum 2 is actuated simultaneously with a reactor scraming signal, the cold liquid is sucked from the bottom section of the plenum 2 and discharged from an outlet nozzle section 10. As a result, a flow is produced in the plenum 2 and the temperature layering phenomenon can be prevented.

Abstract: PURPOSE: To bulk convert a polycrystalline ceramic body into a single crystal body within solid state by heating the polycrystalline ceramic body joined monolithically with a seed crystal above the lowest temp. to get a crystal grain boundary migration but below the m.p. of the body.  
     CONSTITUTION: A solid state polycrystalline ceramic body is joined with a seed crystal having the desired crystal orientation and the same chemical composition as the polycrystalline ceramic body. Subsequently the solid state polycrystalline ceramic body is bulk converted into a single crystal body having the same crystal orientation as the seed crystal by heating above the lowest temp. to get a crystal grain boundary migration but below the m.p. of the polycrystalline ceramic body. Following this process, by heating to 1100-2050°C a combination of a polycrystalline alumina body having ≤100 weight ppm magnesia content and comparatively uniform ≤70 μm grain size and a sapphire body to join them, the polycrystalline alumina body can be bulk converted into the sapphire body by heating again the joined structure to 1,100-2,050°C.

Abstract: PURPOSE:To prevent the reduction of the computing speed of the data of a complement form of '2' for a product sum computing element which can deal with both types of data of the complement form of '2' and a no-code absolute value form. CONSTITUTION:The data of a no-code absolute value form are divided into a part concerning the highest order bit and a part concering only other bits in regard of the multiplication process by the instruction of a selection signal 35. The multiplication of the former part is carried out by a 16-bit adder 31, and the multiplication of the latter part is carried out by a (16X16)-bit multiplier 15 respectively. The computing result of the adder 31 is added to the higher order bit part of the computing result of the multiplier 15 by an adder 33 and inputted to a selector 34. The selector 34 outputs the received result of addition as it is by the instruction of the signal 35. This outputted result is inputted to an adder 17 together with the lower order bits of the computing result of the adder 15. Then the adder 17 and an accumulator 18 totalize successively these computing results. In regard of the data of a complement form of '2', the higher order bits of the computing result of the adder 15 are inputted to the adder 17 via the selector 34. Meanwhile the lower rank bits are directly inputted to the adder 17 respectively.

IPC: F23C6/04
Filed: 1988-09-10
Abstract: PURPOSE:To reduce the NOX by keeping down the flame temperature and accelerate the contact heat transmission so as to reduce the boiler burning chamber in size and weight by disposing a number of heat absorbing water tubes in a single burning chamber which is contiguous to the burner section. CONSTITUTION:A number of heat absorbing water tubes 5b are disposed in a single burning chamber 1. As for the burning method according to different fuel and air supply ratios, burning chambers having heat absorbing water tubes in it are serially connected in three stages, for example. and, in the first stage 11, the lean burning with an air excess of 1.25 air ratio is conducted to control the amount of NOX which is produced immediately, or so-called prompt NOX. In the second stage 12, the reduction ambient burning is conducted by supplying fuel only or adding a small amount of air to the fuel to allow an air ratio of less than one to reduce the NOX and, in the third stage 13, the burning is conducted with the air ratio of about 1.05 which is the final optimum air ratio. Thus, the NOX released from the boiler is reduced, and, at the same time, the size of the boiler is reduced to about 1/2 of conventional devices, allowing the boiler to be compact and light weight.
