Framatome has identified a gap in the range of manufacturing of nuclear reactor equipment. This difference concerns the heat treatment of stress relieving applied to the welded joints made for the assembly of the different components of this equipment. The heat treatment was carried out by applying heating muffles. Framatome has recently demonstrated that this process does not allow to maintain a sufficiently homogeneous temperature over the entire length of the welded joint. Thus, the prescribed maximum temperature was exceeded on some circular portions of the welded joint, while in other portions the minimum temperature was not reached.

Undermined by intellectual inconsistencies and unaffordable issues, the economic debate about the treatment of nuclear waste and its alternatives is beyond rationality. The last public sessions of the National Program for Nuclear Waste and Materials Management (PNGDMR), organized by the National Commission for Public Debate (CNNDP), which have just ended, have been devoted to the economy and financing. downstream of the nuclear cycle. How much will cost Cigeo, can we save from the initial estimate, reserves will be sufficient …? All these questions are important, but their questions are deeply concerned. The problem of long time and taboos. Between the beginning of a reactor and its shutdown, it runs from 50 to 70 years. Its dismantling is spread over a period of around 50 years. Nuclear radioactive material (uranium, plutonium, minor actinides) remains radioactive, industrial processes of reprocessing, storage Potential storage of nuclear materials and high-level waste spans the times that often exceed the century.
