ANALISIS PERBANDINGAN KINERJA PERANGKAT BAHAN BAKAR PLTN TIPE PWR AP 1000 DAN PWR 1000 MWe TIPIKAL DENGAN MENGGUNAKAN PROGRAM KOMPUTER
Abstract: Investigation of
fuel element thermal-hydraulic characteristic is important step related to aspect
of fuel bundle reactor design. This paper analyzes of the PWR AP1000 and PWR
1000 MWe Typical of fuel bundle thermal-hydraulic using RELAP5 code. Choosing
PWR AP 1000 and PWR 1000 MWe Typical because the both of them have almost same
power that is 3400 MWth and 3410 MWth but have differences on fuel bundle sum,
the high of active core, and rod diameter. On the fuel bundle, there are 17x17
fuel rods that have a radial factor the power varies. Modelling of fuel bundle
are divided into 4 channel groups, ie. power factor of 1.396, range power
factor of 1.203 to 1.394, power factor of le then 1.198 down and bypass
channel. Axially, the channels are divided into 3 zones there are stand-off assembly
at the bottom, an active length of the channel and the zone of upper plenum.
The active length divided into 10 axial nodes. The goal of this analysis is
fuel bundle design validation of PWR AP 1000and PWR 1000 MWe Typical and get
thermal-hydraulic comparison for steady-state condition. The analysis result
including cooling floe rate, axial temperature distribution of cladding and
cooling temperature, heat flux and pressure drop. In steady condition, the
model was verified with the parameter of AP-1000 and PWR 1000 thermal-hydraulic
design in which shows a good agreement. Verification results show that the
model is made still need refinement, however qualitatively within realistic
limits. Further updating of the model will be done to get a better verification
results.
