Performance and management of IPR-R1 fuel elements
Description
The performance of fuel elements during the 23 years of the reactor operation, is presented aiming to introduce improvements in the fuel load distribution and consequent increase of the reactivity. A computer code CORE was developed aiming to calculate the individual burnup of the fuel elements and the value of the reactivity for several core configurations, establishing a routine to control the nuclear material in the IPR-R1. The values calculated were compared with the experimental results. Some alternatives to augment the reactivity of the present core are presented foreseeing the fuel load availability for operation with 100Km and, for angmenting the power reaction in a next stage.

Relata-se a avaliacao do desempenho dos elementos combustiveis ao longo de 23 anos de operacao do reator, com objetivo principal de introducao de melhorias para a distribuicao de carga combustivel e consequente aumento do excesso de reatividade. Um programa de computador CORE foi implantado para esse fim, o qual permitiu calcular a queima individual dos elementos e o valor da reatividade nas diversas configuracoes do nucleo, estabelecendo rotina para controle de material nuclear no IPR-R1. Os valores calculados no programa foram comparados com resultados experimentais, obtendo-se a concordancia. Sao apresentadas alternativas para aumento do excesso de reatividade do nucleo atual, prevendo-se disponibilidade de carga combustivel para operacao no regime atual de 100 KW e, para o aumento de potencia do reator em proxima etapa.
