A UK National Thermal-Hydraulics Facility (NTHF) dedicated to supporting new reactor and other relevant business is being developed, one of the purposes deliver on government’s carbon emission reduction commitments. The facility site foreseen be at Menai Science Park isle Anglesey in North Wales, a region expected see significant low energy deployment coming years. NTHF envisioned cater for nee...

The aim is to give an understanding of the numerical approximation and solution of physical systems, especially in open channel hydraulics, but with more general application in hydraulics and fluid mechanics generally. The marriage of hydraulics and computations has not always been happy, and often unnecessarily complicated methods have been developed and used, when a little more computational ...

The RELAP5/MOD3.2 R/T engineering quality plant simulation code has been developed based on the system thermal-hydraulics code RELAP5 and the nodal spatial kinetics code NESTLE. Preliminary validation of the code as an engineering simulator was performed using a series of NEA PWR control rod ejection and withdrawal problems. Real time performance for simulator applications was demonstrated for ...

The Xi’an Pulsed Reactor (XAPR) is characterized by its small core size and integrated fuel moderator structure, which results in a non-uniform power temperature distribution. Consequently, complex coupling relationship exists between neutronics thermal hydraulics, necessitating the assurance for operational safety of XAPR. To optimize experimental scheme reactor, refined three-dimensional stea...
