Responses to questions by Newal
Agnihotri, Editor of Nuclear Plant
Journal.
1.
Can HydroAire supply spare parts
“on demand” to the plants?
While HydroAire does not stock
parts, these can in certain cases, be fast-
tracked to ensure the earliest possible
delivery. Where deemed necessary, and
as part of a wider agreement, parts can be
stocked to guarantee same, or next day,
delivery.
2.
How is the challenge of obsolescence
handled, where a safety-related pump
manufacturer is out of business?
Obsolescence is a very important is-
sue within the nuclear fleet of plants. Hy-
droAire has been pro-active in supporting
our customers with these obsolescence
issues. The first step is the need being
communicated to our Account Manager.
In order to ensure suc-
cess we require the
Bill of Material and
General
Assembly
drawing of the pump
in question. Our en-
gineering team will
then review the exist-
ing design checking
materials, configura-
tion, and method of
operation. Addition-
ally, we will ask the
customer if there are
any issues with the
existing pumps’ oper-
ation that may affect
availability or reliability. If so, we will
seek to incorporate any required modifi-
cation through a design change package
with which we will support the plant. In
the design change package we would ad-
dress the modification through a failure
mode analysis and also perform a seismic
analysis. In addition we will create a list
of critical characteristics of the modified
component. We would submit all relevant
documentation in a design change pack-
age.
In many cases the client elects not
to perform any changes or modifications;
instead requesting an identical pump with
equivalent components.
Once HydorAire’s engineering has
performed its review and we accept the
project, we request the client to ship the
components to HydroAire. Upon receipt,
we will disassemble the pump and create
a bill of material of the actual parts

NuScale Power has created a new kind of
nuclear power plant, an innovative design
that incorporates all of the components for
steam generation and heat exchange into
a single integrated unit, the NuScale Power
Module™ (NPM). The design eliminates
many costly, complex systems while cutting-
edge manufacturing cuts time and cost
of production. The result: a power source
that is simultaneously safe, reliable, scalable,
carbon-free, and economical.
