Diagram of intermediate reactor
This diagram (Fig. 2.2a) is
The hoL-sing (1, 2, 3) is
similar to the previous two diagrams.
the same as in the thermal neutron reactor.
The fuel elements 4 are installed in a shell of structural material
just as in a rapid neutron reactor. The radial reflector 5 is
similar tp that in a fast neutron reactor as is the control, carried
out by cylinder 6 located in reflector 5. Here ýI~oo are the cylinders

Fig. 2.2. Structural diagrams of nuclear reactors: a - on intermediate
neutrons; b - heterogeneous on thErmal neutrons.
Figure ?.2b gives.a structural diagram for a heterogeneous
reactor w•._,h a gaseous working medium.
'The housing 1 of the reactor, the end walls 2, !nd the pipes
for the fuel elements and the passage oP the heau-tr.::icer agent 3
are a r±l~d all-welded des~ign of t'e dirpct-flow type. T'c fuel
elements 4, in the form of plates, shown in the flgur'2 or •.i .ight,
are set by ,ection3 into the pipes 3. The controlling and emergency
rods 5 "_nd 6 are made similarly to the diagram ci' a thermal reactor.
