A nuclear reactor is a system that contains and controls sustained nuclear chain reactions. Reactors are used for generating electricity, moving aircraft carriers and submarines, producing medical isotopes for imaging and cancer treatment, and for conducting research.

Fuel, made up of heavy atoms that split when they absorb neutrons, is placed into the reactor vessel (basically a large tank) along with a small neutron source. The neutrons start a chain reaction where each atom that splits releases more neutrons that cause other atoms to split. Each time an atom splits, it releases large amounts of energy in the form of heat. The heat is carried out of the reactor by coolant, which is most commonly just plain water. The coolant heats up and goes off to a turbine to spin a generator or drive shaft. Nuclear reactors are just exotic heat sources.

Most chemical reactions are faster at higher temperatures and heat exchangers are frequently used to provide the heat necessary to increase the temperature of the reaction.
A common heat exchanger is the shell and tube type (Figures 12 and 13) where one part of the process flows through a tube and the other part around the shell.
A good example where heat exchange is important is in the manufacture of sulfur trioxide from sulfur dioxide in the Contact Process where the excess heat is used to warm incoming gases.
The heat from the reaction is transferred to incoming gases across the tube wall (Figure 12) and the rate of heat transfer is proportional to:
i) the temperature difference between the hot gases and the incoming gases and
ii) the total surface area of the tubes.
Thus the rate of heat transfer required will determine the size of the exchanger but when a chemical reaction also occurs in the exchanger (as in the case of tubular reactors ), it is important to take into account the residence time of the materials (whether they be gases or liquids) in the heat exchanger.

1. - "Pressure Relief Valve"- to protect a system (e.g. pump, pipe segment or tank)
from excessive pressure (in excess of the set point).

2. - "Back Pressure Regulator"- to provide a means of retaining desired system
pressure to points of use in upstream line(s).

3. - "Pressure By-Pass Valve"- to protect a pump from 'dead-heading' by enabling
the flow to by-pass an obstruction.

4. - "Back Pressure Valve"- to provide back pressure directly on the discharge
of a pump to enhance its performance.

5. - "Anti-Siphon Valve"- to prevent unwanted chemical
siphoning through a pump; when negative pressure at a lower elevation could
create a siphon and drain a tank. The valve is set to open at the desired pumping
pressure, but seals tightly when a vacuum occurs downstream.

BOILERS: Boilers and thermal liquid heaters generate heat for use in other operations. They differ in the fluid medium used to transfer this heat.
STEAM: Steam boilers heat water to produce steam, which is then used to generate energy or heat for other processes.
GENERAL INFORMATION: Boilers are used to generate steam that then provides heat or power. Water is converted to steam in the boiler. This steam travels through the heating apparatus which can be any piece of equipment that requires steam for operation. The cooled steam is then condensed into water and returns to the boiler to start the cycle again.
USAGE EXAMPLES: Most fire tube boilers are portable and are used in oil fields, saw mills, and at construction sites to generate heat or power. Water tube and cast iron boilers may be solid-fuel fired, or they may operate on standard liquid and gas fuels. The water tube boiler below operates on gas fuel and is part of a co generation plant where heat from the fuel is simultaneously converted into electrical and thermal energy.
