English

Subject field(s)
  • Scientific Instruments
  • Nuclear Fission Reactors
DEF

Ratio of the maximum heat flux to the average heat flux in a nuclear reactor.

CONT

Hot-Spot Factor. The maximum value of FQ occurs where the local power density ofr linear heat rate is greatest. It is referred to as the hot-spot factor because of the relationship to maximum temperatures in a fuel pin. The hot-spot factor limits are set to prevent : 1. melting of fuel; 2. cladding-coolant interactions following loss of cooling capability.

OBS

hot spot factor : term and definition standardized by ISO.

French

Domaine(s)
  • Instruments scientifiques
  • Réacteurs nucléaires de fission
DEF

Rapport du flux calorifique maximal au flux calorifique moyen dans l’ensemble d’un réacteur nucléaire.

OBS

facteur de sécurité au point chaud : terme et définition normalisés par l'ISO.
