Assessment of SBO Fukushima likewise scenario for an IPWR design with RELAP5MOD33 and RELAPSCDAPSIMMOD3. 5 codes Martínez Quiroga, Víctor Manuel; Pérez-Ferragut, Marina; Pericas Casals, Raimon; Freixa Terradas, Jordi (2022)
Open AccessIn recent years Small Modular Reactors (SMR) have become very popular within the nuclear industry. These designs allow to reduce costs as well as to enhance the safety due to passive nuclear safety features. Within these ...
Code improvement and model validation for Asco-II Nuclear Power Plant model using a coupled 3D neutron kinetics/thermal-hydraulic code Pericas Casals, Raimon; Ivanov, K; Reventós Puigjaner, Francesc Josep; Batet Miracle, Lluís (2016-01-01)
Open AccessThis paper provides a Best Estimate validation calculation with a coupled thermal–hydraulic and 3D neutron kinetic model for Ascó-II Nuclear Power Plant. Common NRC codes have been used for its purpose. TRACE is the code ...
Comparison of best-estimate plus uncertainty and conservative methodologies for a PWR MSLB analysis using a coupled 3-D neutron-kinetics/thermal-hydraulic code Pericas Casals, Raimon; Ivanov, K.; Reventós Puigjaner, Francesc Josep; Batet Miracle, Lluís (2017-05-04)
Open AccessThis paper compares the Best-Estimate Plus Uncertainty (BEPU) methodology with the Conservative Bounding methodology for design-basis-accident analysis. Calculations have been performed with TRACE [for thermal-hydraulic ...
Contribution to the validation of best estimate plus uncertainties coupled codes for the analysis of NK-TH nuclear transients Pericas Casals, Raimon (Universitat Politècnica de Catalunya, 2015-05-15)
Open AccessThe calculations that allow the operating license of the nuclear reactors are usually made using conservative methods. This conservatism, often excessive, limits the actual capabilities of the industry to increase energy ...
Multi-physics framework for whole-core analysis of transient fuel performance after load following in a pressurised water reactor Peakman, Aiden; Gregg, Robert; Bennett, Tom; Casamor Vidal, Max; Martínez Quiroga, Víctor Manuel; Freixa Terradas, Jordi; Pericas Casals, Raimon; Rossiter, Glyn (2022-08-01)
Restricted access - publisher's policyThe increasing deployment of renewable energy sources and greater electrification of demand is requiring more frequent use of load following in pressurised water reactors (PWRs) . A limiting aspect with respect to load ...
