4.4 MSR Performance Tests
4.4.1 Scope
TEI will provide a sufficient number of internal sensors and provisions for
the lead wires or pressure tubing to exit the pressure boundary (proprietary -
see photographs at end of chapter), as well as locally mounted read-out
devices so as to be able to gather and record data which positively indicates
internal performance. Performance verification instruments will be installed
on the four MSR vessels to determine performance parameters. The internal
sensors will be located in zones which are indicative of the actual
thermohydraulic events.
TEI has had a great deal of practical experience in the planning of data
requirements, hardware, installation, and recording. Our engineering
Methods Group is highly qualified to evaluate such data and assess its impact
on plant parameters.
The performance of the MSRs will be verified by the direct measurements of
pressures, temperatures and flow rates of steadcondensate around each
reheater and vessel. All pressure taps will be installed with isolation valves
supplied by TEI, ready for connecting to the pressure gauges. All
temperature connections will be fitted with thermowells or thermocouples.
Annubars or equivalent meters, will be used to measure the steam and
condensate flow rates. Other data required for heat balance calculations will
be mutually established with CR-3 personnel.
TEI will prepare data sheets in a format which allows a complete and a
consistent recording of all data necessary for the performance verification.
TEI will coordinate and participate with your plant personnel in recording the
data and evaluating same, as requested.
