Numerical Modeling of Tube Forming by HPTR Cold Pilgering Process

Roland Logé

For new fast-neutron sodium-cooled Generation IV nuclear reactors, the candidate cladding materials for the very strong burn-up are ferritic and martensitic oxide dispersion strengthened grades. Classically, the cladding tube is cold formed by a sequence o ...

Investigation of P-V and V-Q based optimization methods for voltage and reactive power analysis

Sidi-Rachid Cherkaoui, Omid Alizadeh Mousavi

The management of voltage and reactive power control sources considering the voltage stability is a challenging issue for secure operation of power systems. Generally the analysis of the stability margin is performed using P V and V Q based approaches. Thi ...

Analysis of selected Phenix EOL tests with the FAST code system - Part I: Control-rod-shift experiments

Rakesh Chawla, Konstantin Mikityuk, Aurélia Chenu

The end-of-life (EOL) tests recently performed at the Phenix reactor present a unique opportunity to validate computational tools used for Sodium-cooled Fast Reactor (SFR) static and transient analysis. In the first part of the current study, PSI's FAST co ...

A novel design approach for a neutron measurement station for burnt fuel

Rakesh Chawla, Mathieu Hursin

The design and characterization of a passive neutron measurement station for highly burnt fuel has been undertaken at the Paul Scherrer Institute (PSI). The measurement station aims at the determination of the total neutron emission rate of full-length lig ...

Experimental investigation of moderator density variation effects in an SCWR-like fuel lattice

Rakesh Chawla

Reaction rate distribution measurements are reported from experiments in an SCWR-like test lattice performed with separated moderator and coolant regions. This work was done at the zero-power research reactor PROTEUS at the Paul Scherrer Institute in Switz ...

Molybdenum boride and carbide catalyze hydrogen evolution in both acidic and basic solutions

Xile Hu, Heron Vrubel

Molybdenum boride (MoB) and carbide (Mo2C) are excellent catalysts for electrochemical hydrogen evolution at both pH 0 and pH 14. ...

Experimental validation of control rod related perturbations of moderator regions in an SCWR-like fuel lattice

Rakesh Chawla

Two different types of perturbations of an SCWR-like fuel lattice have been investigated experimentally in the central test zone of the PROTEUS zero-power research reactor at the Paul Scherrer Institute in Switzerland. In each case, a campaign of high-reso ...
