Vim li cas aluminium alloy 6061 feem ntau siv nyob rau hauv nuclear reactor Cheebtsam?
Alloy 6061 muaj kev ua kom zoo neutron nqus cov khaub lig - teb (0.23 barns) rau kev thaiv hluav taws xob. Nws corrosion tsis zoo tshaj 10,000 teev nyob rau hauv cov tshuaj tua dej hauv cov tshuaj tiv thaiv dej (paw) ntawm 300 degree. Lub Tem Tem Fem muab 310 mpa kom muaj zog rau cov ntawv thov txheej txheem. Tsis ntev los no Ioonse cov lus qhia (SSG-45, 2025) Txoj cai txiav txim nws siv nyob rau hauv cov pas dej roj. Piv rau zirconium alloys, nws txo nws cov kev pheej hmoo hydrogen ntau los ntawm 62%.
Aluminium ua ua li cas hauv high - hluav taws xob ib puag ncig piv rau lwm cov hlau?
Txhuas tswj qhov seem ruaj khov txog li 10 ^ 18 lub neutrons / cm² flux, outperforming hlau. Nws qhov chaw ua haujlwm qis ua cov khoom luv luv- nyob isotopes (al {{12} {{12} - Lub Neej: 2.24 feeb). Lub 2025 iTer Project lees paub tseeb Aluminium's superonority tshaj titanium rau fusion reactor ua ntej phab ntsa. Txawm li cas los xij, nws ua brittle sab saum toj 150 qib hauv cov neeg yug rog sai. Tshiab aluminium- scandium alloys (al-sc-0.5%) Peb npaug kev puas tsuaj rau kev ua siab ntev.
Dab tsi yog cov qauv tam sim no rau txhuas cladding hauv nuclear roj rods?
ASTM B209-25 qhia meej 99.99% kev coj dawb huv rau Uranium roj cladding. Thickness yuav tsum yog 0.38 ± 0.02mm nrog saum npoo roughness<0.8µm RA. NRC 10CFR50.46 now requires self-passivating oxide layers >50nm. Tshaj tawm - Kev kuaj kab txawv teb chaws} irradiation yuav tsum muaj<0.1% swelling after 18 months. South Korea's APR-1400 reactors use nano-laminated aluminum-zirconium cladding for 40% longer lifespan.
Yuav ua li cas txhuas kev siv nyob rau hauv Nuclear Txhiav Cov Tshuab Khov?
High - Purity Aluminium (99.999 %%} {Resistant Barriers Hauv Ntau}} Txheej khib nyiab canisters. Tus 2025 Doe txheem txheem ua kom 10cm -} tuab txhuam cov plhaub rau plutonium cia. Anodized txheej tswj kom tiv thaiv microbial - inducle corrosion hauv cov chaw tsheb thauj khoom hauv av hauv av. Aluminium Matrix Composites nrog Boron Carbide muab cov kev tiv thaiv neuron rau kev thauj khoom roj. Switzerland Lub chaw tshiab Zwilag tshiab siv Aluminium-}} Cov kab ntxau rau cov khib nyiab vitrified rau Vitrified pov tseg.
Dab tsi tshwm sim txhuas thev naus laus zis yog hloov nuclear decommissioning?
Robotic txhuas ua npuas dej txau tshuab tam sim no Foob cov chaw tsis huv nrog 95% efficiency. Cov duab - nco couminium alloys pab rhuav tshem cov cheebtsam tsis muaj kev txiav. UK lub NDA tsim txhuas-} Raws li cov chelatory. Nyiv lub alps - ich siv nanoporous aluminium lim rau tritium scasing rearer reactor dismantling nrog 30% txo nqi.
