摘要

The nuclear power plant Atucha I is in operation from 1974. It is a power station of the type PHWR with a power of 357 MW and with a temperature of operation of 262℃. The nucleus this formed at the present time by 252 fuels channels. The fuels are of 37 bars, one structural and 36 fuels bars of natural uranium with 0,85% enrichment and of a longitude of 6,18 meters. This nucleus this inside a vessel of a steel 22NiMoCr37 and built with badges of different cast. For the characteristics of their design the top of the reactor cannot be retired without a high radiological and economic cost. This takes to that took the decision of placing the samples of the surveillance program in the bottom part of the fuels channels. Initially they were placed two set of test of samples that they should be extracted to 50% and the end of the life of the power plant. This situation takes to design a program of irradiations in experimental reactors, we irradiates material in SCK-CEN in Belgium, with an acceleration of 700 times, showing the material a similar behaviour to the VAK. We irradiates material in Lovissa, Finland, with a factor of advance of 24 times if being necessary it will be irradiated in the reactor RA1, in Argentina. Everything with the purpose of knows the current state of the recipient. In this work this irradiations are analysed, being compared the results and the importance of this knowledge was commented for the design of the surveillance programme of Atucha II.
