BOTANI: High-fidelity multiphysics model for boron chemistry in CRUD deposits

Nuclear Engineering and Technology, 2021
We develop a new high-fidelity multiphysics model to simulate boron chemistry in the porous Chalk River Unidentified Deposit (CRUD) deposits. Heat transfer, capillary flow, solute transport, and chemical reactions are fully coupled.

The DISNY facility for sub-cooled flow boiling performance analysis of CRUD deposited zirconium alloy cladding under pressurized water reactor condition: Design, construction, and operation

Nuclear Engineering and Technology, 2023
The CRUD on the fuel cladding under the pressurized water reactor (PWR) operating condition causes several issues. The CRUD can act as thermal resistance and increases the local cladding temperature which accelerate the corrosion process.

A Combined Method for Predicting the Boron Deposited Mass and the CIPS Risk

Science and Technology of Nuclear Installations, 2019
CIPS is a shift in the axial power towards the bottom half of the core, also known as axial offset anomaly (AOA), which results from the deposited of corrosion products during an operation. The main reason of CIPS is the solute particles especially boron

Two-phase Boiling Heat and Mass Transfer Characteristic within PWR CRUD Deposition

Yuanzineng kexue jishu, 2022
The porous chalk river unidentified deposit (CRUD) depositions not only increase the thermal resistance and lead to the deterioration of heat transfer, but also change the power distribution as a result of boron hideout. Therefore, accurate prediction of

Development of boron tracking and boron hideout (CRUD) model based on subchannel approach

Nuclear Engineering and Design, 2018
Abstract In order to keep the reactor criticality, chemical shim is universally used for the control of pressurized water reactors (PWRs). In other words, it is vital to maintain the boric acid concentration uniformly distribution in the primary cycle.
