Den föreliggande uppfinningen gör det möjligt att markant förbättra bränsle- rörets resistens mot spänningskorrosion. Enligt uppfinningen uppnås detta genom att zirkoniumet på. kapselrörets insida. bringas att innehålla 0,1-3 viktprocent molybden och/eller 0,034 viktprocent kol, och/eller 0,034 vikt- procent fosfor och/eller 0,034 viktprocent kisel. Zirkoniumet kan dessutom innehålla i föregående stycke angivna andra i kommersiell zirkoniumsvamp av reaktorkvalitet ingående föroreningar i där angivna. halter.The present invention makes it possible to markedly improve the resistance of the fuel pipe to stress corrosion. According to the invention this is achieved by turning the zirconium on. the inside of the canister tube. are made to contain 0.1-3% by weight of molybdenum and / or 0.034% by weight of carbon, and / or 0.034% by weight of phosphorus and / or 0.034% by weight of silicon. The zirconium may additionally contain other impurities contained in the preceding paragraph in commercial zirconium fungi of reactor grade contained therein. halter.
En tänkbar förklaring till den uppnådda förbättringen är följande. Vid till- verlcning av ett kapselrör med invändigt zirkoniumskikt, vilket kan ske genom strängsprutning, utsättas materialen för högre temperaturer. Detta medför att en korntillväxt äger rum i zirkoniumet, som är snabb i fallet med det kända zirkomiumskiktet, där legeringsämnena är lösta. Vid 'tillsatser av molybden, kol, fosfor eller kisel i ovan angivna halter sker en urskilj- ning av stabila föreningar, såsom intermetalliska. föreningar, karbider, fosfider och silicider, i form av fria partiklar i zirkoniummatrisen.A possible explanation for the improvement achieved is the following. When manufacturing a canister tube with an inner zirconium layer, which can be done by extrusion, the materials are exposed to higher temperatures. This means that a grain growth takes place in the zirconium, which is fast in the case of the known zirconium layer, where the alloying elements are dissolved. In the case of additions of molybdenum, carbon, phosphorus or silicon in the above-mentioned levels, a distinction is made between stable compounds, such as intermetallics. compounds, carbides, phosphides and silicides, in the form of free particles in the zirconium matrix.
Denna urskiljning förhindrar komtillväacten, så; att en struktxir med korn erhålles i zirkoniumet än i det kända fallet. Den annorlunda, fin- kornigare strukturen är ansvarig för den ökade resistensen mot spännings- korrosion. I Tjockleken hos zirkoniumskiktet uppgår enligt uppfinningen till 0,005-0,8 mm och företrädesvis till 0,05-0,1 mm.This discernment prevents the comet, so; that a structure with grains is obtained in the zirconium than in the known case. The different, finer-grained structure is responsible for the increased resistance to stress corrosion. According to the invention, the thickness of the zirconium layer is 0.005-0.8 mm and preferably 0.05-0.1 mm.
Den zirkoniumbaserade legeringen, på vars insida zirkoniumskiktet är anord- nat, utgöres' företrädesvis av en zirkonium-tenn-legering, t ex de under han- delsnamnen Zircaloy 2 och Zircaloy 4 kända zirkoniumbaserade legeringarna, vilkas innehåll av legeringsämnen ligger inom gränserna 1,2-1,7 viktprocent för tenn, 0,0?-0, 24 viktprocent för järn, 0,05-O,15 viktprocent för krom, 0-0,08 viktprocent för nickel, 0,10-0,15 viktprocent för syre, rest zirkoniumThe zirconium-based alloy, on the inside of which the zirconium layer is arranged, is preferably a zirconium-tin alloy, for example the zirconium-based alloys known under the trade names Zircaloy 2 and Zircaloy 4, whose content of alloying elements is within the limits of 1,2 -1.7% by weight for tin, 0.0? -0.24% by weight for iron, 0.05 -0, 15% by weight for chromium, 0-0.08% by weight for nickel, 0.10-0.15% by weight for oxygen , residual zirconium
