Title of Paper:

Subchannel Analysis of Wire Wrapped SCWR Assembly

Journal:

Science and Technology of Nuclear Installations

Summary:

Application of wire wrap spacers in SCWR can reduce pressure drop and obtain better mixing capability. As a consequence, the
required coolant pumping power is decreased and the coolant temperature profile inside the fuel bundle is flattened which will obviously decrease the peak cladding temperature.The distributed resistance model for wire wrap was developed and implemented in ATHAS subchannel analysis code. The HPLWR wire wrapped assembly was analyzed.
