          Abstract

          Two load following (LF) tests on CANDU type fuel elements were performed in TRIGA Research Reactor of INR Pitesti. In the first LF test the 78R fuel element has successfully experienced 367 power cycles, mostly between 23 and 56 kW/m average linear power. In the second LF test, the fuel element withstood 200 power cycles from 27 to 54 kW/m average linear power as well as additional ramps due to reactor trips and restarts during test period. New LF tests are planed to be performed in order to establish the limits and capabilities for CANDU fuel in LF conditions. This paper presents the results of the LF tests performed in TRIGA Research Reactor and their relation to CANDU fuel performance in LF conditions.

          Kurzfassung

          Zwei Tests wurden nach der Beladung (LF) mit Brennelementen vom CANDU-Typ am TRIGA Forschungsreaktor des INR Pitesti durchgeführt. Beim ersten LF Test hatte das 78R Brennelement erfolgreich 367 Leistungszyklen meist bei durchschnittlicher Leistung zwischen 23 and 56 kW/m absolviert. Beim zweiten LF Test widerstand das Brennelement 200 Leistungszyklen zwischen 27 and 54 kW/m durchschnittlicher linearer Leistung, sowie zusätzlichen Anstiegen aufgrund von Reaktor Schnellabschaltungen und Neustarts während der Testperiode. Neue LF Tests sind geplant, um Grenzen und Leistungsvermögen für CANDU Brennelemente unter LF Bedingungen zu bestimmen.
