In the last years, it operates at 4.5MW for 8h on Mondays, Tuesdays and Wednesdays. In every day of operation, a sample is taken from the pool water both before starting the reactor and at the end of the day and analyzed in an HPGe detector, in order to verify for possible problems with the fuel elements or other issues. In this work, the results obtained in these analyses spanning for some months are discussed regarding the radionuclides frequently identi ed and the dependence of their activities with time.579-583openAccessfuel elementshigh-purity ge detectorsiear-1 reactorradiochemical analysisradioisotopesradiometric analysistime dependencewaterTexto completo de evento0000-0002-6318-6805https://orcid.org/0000-0002-6318-6805https://orcid.org/0000-0002-9351-9201https://orcid.org/0000-0003-3237-8588
