Why does air must be excluded from the reactor vessel during cracking?

Disclosed is a method for preventing hydrogen-induced disbanding of austenitic stainless steel cladding, which is made on a low alloy steel, in a reactor vessel which has been used in a high-temperature and high-pressure hydrogen atmosphere so the air must be excluded. The clad steel is cooled from its operating temperature to a temperature which is not lower than 100° C. Then, the clad steel is maintained at a temperature between said temperature which is not lower than 100° C. and a post weld heat treatment so as to effect hydrogen degassing treatment. Thereafter, the clad steel is further cooled.

What are the functions of pressure vessel and turbine in a nuclear reactor?
The pressure vessel contains the reactor core with its fuel, coolant, moderator, control elements, and emergency systems. The turbine is the device that on receiving the steam it spins and turns the electric generators to produce electricity.
Does an operating nuclear reactor make a lot of sound?
The reactor itself does not make a lot of sound when operating. Nuclear fission is silent, but moving water in the core (in a pressurized water reactor) might be heard as it circulates. But it would not be easy to put your ear to the reactor vessel as radiation levels would be very high and the vessel would be very hot. Certainly the pumps that are running to circulate coolant will be audible.
Why is the reactor core of a nuclear reactor in a thick steel vessel surrounded by concrete walls?
The thick steel vessel is to contain the high pressure of the water in the reactor, the concrete is to provide radiation shielding, for the operating crew mainly but also to prevent outside equipment from becoming irradiated
What is the function of shielding in a nuclear reactor?
The first line of shielding is to limit the neutron bombardment of the pressure vessel, to give it a safe life of 40 or more years. Then you need to protect personnel who have to go into areas close to the reactor for maintenance, and also to limit the exposure of equipment which may need maintanance done during the life of the plant
What are the two structure that produce chemicals that can kill bacteria?
A still for producing alcohol and a reactor vessel for producing all sorts of other chemicals with antiseptic properties.
How big is the reactor vessel in a boiling water reactor?
A reactor vessel in a boiling water reactor is approximately 300 tons.
What is stirred vessel reactor and its configuration?
'Stirred vessel'? Not an expression I know.
What are the necessary components for a nuclear reactor?
for pressurized light water reactor type, as an example, the nuclear reactor components are * Reactor vessel (that contains the nuclear fuel and surrounded with water and contains control rod for power control and for safety) * reactor coolant pump * steam generator * reactor pressurizer * piping out of the vessel to the pressurizer, from pressurizer to steam generator, from steam generator to reactor coolant pump, and from pump back to the reactor vessel.
What is a part of a nuclear power plant that undergoes a fission reaction?
Nuclear fission takes place in the nuclear fuel rods that are placed in the reactor core that is situated in the reactor pressure vessel. The reactor pressure vessel is usually situated inside the reactor containment.
Fuel rods in the reactor vessel are made of?
Uranium-235
What is powered by a nuclear reactor?
A steam turbine/generating unit, or a naval vessel
What part of a nuclear power plant that undergoes a fission reaction called?
the reactor vessel
What would happen if the base of a containment vessel were made out of the same material as the control rods during a nuclear meltdown?
Making the base of a reactor vessel out of a neutron absorbing material like the control rods are made out of (like boron) would have little effect on a meltdown. The primary source of heat in a meltdown is the radioactive decay of fission fragments. This decay heat cannot be stopped by anything. It can only be carried away by a coolant of some kind. If a meltdown is severe, the molten fuel and cladding will pool on the bottom of the reactor vessel and melt through it. This will be true in a gross meltdown regardless of the material from which the reactor vessel bottom is made.

Why the steam inlet at the top and coolant circulation from bottom of the reactor why we can't use the glass lined reactors for alkali reactions?
In the PWR the top houses the steam outlet, not inlet, and coolant flow is applied to the pressure vessel inlet connections. A glass lined vessel would simply not be durable enough for a 40 or hopefully 60 year life. If it started cracking or peeling off, how would it be repaired?
