SUMMARY
I . Project Title
Conceptual Design of Reactor Coolant Pump of Integral Test Facility for
Simulating PWR
II. Objective and Importance of the Project
In the design of integral test facility currently carried out in KAERI, the
reactor coolant pump provides sufficient forced flow to primary coolant
system and provides the same temperature distributions in the primary
system to the reference plant. At the initial blowdown phase of small break
LOCA, the behavior of the reactor coolant pump can affect the core flow and
system behavior, and thus can change overall accident scenario. Therefore,
proper scaling analysis should be performed to correctly simulate the
reference reactor coolant pump. This report presents the scaling analysis
results and provides design data for reactor coolant pump of integral test
facility.
III. Scope and Contents of Project
This report includes the basic information on general reactor coolant pump
and the scaling methods for reactor coolant pump used in conventional
integral test loops. The conceptual design of reactor coolant pump is
performed using scaling laws.
IV. Result and Application of Project
This report is thought to be very useful for the design and selection of
the reactor coolant pump of integral test facility, and is expected to be used
as a guide for the detailed design
operational and accidental transients
in view of thermal hydraulics.
of reactor coolant pump to simulate the
to be occurred in the integral test facility

Abstract(15-20 Lines)
In the design of integral test facility currently carried out in KAERI, the reactor coolant
pump provides sufficient forced flow to primary coolant system and provides the same
temperature distributions in the primary system to the reference plant. At the initial
blowdown phase of small break LOCA, the behavior of the reactor coolant pump can affect
the core flow and break flow, and thus can change overall accident scenario. Therefore,
proper scaling analysis should be performed to correctly simulate the reference reactor
coolant pump. This report presents the scaling analysis result and provides design data fox
reactor coolant pump of integral test facility. This report summarizes basic inforrnations
about reactor coolant Pump. Also, this report includes the parameters of general reactor
coolant pump and the scaling methods for reactor coolant pump used in conventional
integrel test loops. Fhmlly, the conceptual design of reactor coolant Pump is performed using
scaling laws. This report is thought to be very useful for the design and selection of the
reactor coolant pump of integral test loop, and is expected to be used as a guide at the
detailed design of reactor coolant pump to simulate the operational and accidental transients
to be occurred in the integral test looP in view of thermal hydraulics.
