A discussion OF some sf the important assmptiofts ana results for
the major accounts follows e
Account 21. Structures and improvements. The primary and major
structure in the DMSR plant is the reactor containment building. While
layouts of internal areas would differ, comparable costs with the PWR
are expected. An allowance has been entered for plant lifetime storage
of radioactively contaminated items including provisions to facilitate
decommissioning operations.
The other structures parallel the PWR structures in cost. The tur-
bine rooms are considered comparable. A supercritical steam turbine for
the DMSR is considerably smaller than a PWR turbine, but space was allowed
for extra piping and equipment that may be required to adapt the super-
critical system to a molten-salt steam generator.
Space was also allowed
for handling and storing coolant salt fog. noma1 operations and for
