The stability analysis was performed on a new CMFD method (lpCMFD) for both k-eigenvalue problem (EVP) and transient fixed source problem (TFSP), and an unconditionally stable variant of lpCMFD method was presented in this paper. The lpCMFD is a new

Verification and Validation (V&V) serves an important role in assessing the numerical methods implemented in a neutron transport code. However, very few benchmarks are available for verifying and validating the transient capability of neutron transpo

Coarse Mesh Finite Difference (CMFD) method is a very effective method to accelerate the iterations for neutron transport calculation. But it can degrade and even fail when the optical thickness of the mesh becomes large. Therefore several methods, i

Partial convergence of CMFD can help to stabilize multiphysics iteration schemes. In this paper, an efficient multiphysics iteration scheme with near-optimal partially convergent CMFD implemented in MPACT is presented. In the new scheme, the feedback

Mesoporous carbon (m-C) has potential applica- tions as porous electrodes for electrochemical energy stor- age, but its applications have been severely limited by the inherent fragility and low electrical conductivity. A rational strategy is presente
