ORNL-2106 - the Molten Salt Energy Technologies Web Site

ANP PROJECT PROGRESS REPORT
the necessary information for two of the six lnconel
shells is available, and Lycoming is expediting
work on these two shells. Additional design in-
formation is still needed for the remaining shells,
but mandrels are being rough machined for pro-
ducing them.
The beryllium reflector for the ETU is being
machined by The Brush Beryllium Co., but some
information on this item is still lacking because
of design modifications, The island holes are
now being drilled at ORNL and the island will
be sent to The Brush Beryllium Co. for contouring
when this operation is completed.
The heat exchanger suppliers are still studying
assembly methods and techniques for fabricating
the channel sections of the fuel-to-NaK heat ex-
changers. Potentially, this equipment still appears
to be one of the controlling factors in the assembly
schedule.
Orders for the boron carbide tiles and boron-
copper cermets have been placed with the Norton
Company and the Allegheny Ludlum Steel Corp.,
respectively. A fabricator has not yet been se-
lected to form the boron-copper cermets into the
desired shapes.
Fabrication of the heavy l-in.-thick pressure
shells, which must be specially formed, will re-
74
quire equipment that is not widely available.
Because of the special dies which will be re-
quired, the delivery of these heavy shells may
also affect the reactor comptetion date.
Knapp Mills, lnc.; has been selected as the
supplier of the lead shielding, which will be pre-
formed and bolted to the reactor. It is proposed
that only the side pieces be mounted on the ETU
because of space and time considerations. No
design drawings are available to describe the
water shield, but it is anticipated that this, too,
will be prefabricated.
A number of jigs and fixtures for use in assembly
have been designed and are being procured. These
include fixtures for assembling the reflector-
moderator, assembly and checking fixtures for
the main heat exchangers, templates and a gage
for checking the shells, and several handling
devices.
An area in Building 9201-3 is now being modi-
fied for use as a reactor assembly area. The
area will be enclosed and air-conditioned, and
it will be serviced by an overhead crane. It is
anticipated that the area will be ready for use
when the first reactor parts arrive in August.
