Zirconium: Tus ORUG OFFOD ntawm Nuclear Hwj Chim

Nyob rau hauv lub ntiaj teb cov ntsiab lus ntawm kev ua kom muaj zog thiab huv lub zog, lub hwj chim nuclear ib txwm ua lub luag haujlwm tsis tseem ceeb. Lub neej uas ua haujlwm kom muaj kev nyab xeeb thiab cov khoom siv hluav taws xob nuclear nyob hauv qhov tseem ceeb ntawm reasor - Cov khoom siv roj. Ntawm lawv, ib qho hlau hu ua "zirconium"Tau dhau los ua tus neeg tsis paub txog kev nyab xeeb ntawm qhov kev nyab xeeb ntawm no" vim nws qhov kev ua tau zoo tshaj plaws hauv kev txhim kho tshiab thiab kev lag luam kev lag luam.
1, the irreplaceable 'Tus Saib Xyuas Xeev Txog': tus tseem ceeb ntawm zirconium
Vim li cas zirconium? Cov lus teb stems los ntawm ob lub innate tistents:

• Qhov kawg Neutron Kev Lag Luam: Zirconium muaj hla dhau ntawm qhov tsis zoo, uas tau ua kom muaj zog ntawm kev siv cov tshuaj tiv thaiv kev siv hluav taws xob, uas tau txhim kho kev siv hluav taws xob, uas tau ua kom zoo dua qub
• Zoo heev corrosion resprier: nyob rau hauv lub siab kub, kev kub siab thiab ruaj khov thiab ruaj khov yeeb yaj kiab tuaj yeem tsim nyob rau saum npoo ntawm zirconium alloy. Zaj yeeb yaj kiab no zoo li "armor", muaj txiaj ntsig zoo thaiv cov xeb ntawm cov roj nuclear ntawm cov dej txias thiab khov kho hauv cov khoom siv hluav taws xob.

Nws yog qhov tseeb tau ob tus cwj pwm uas ua rau zirconium alloy qhov kev xaiv uas nyiam tshaj plaws rau kev tsim cov roj nuclear roj, tshwj xeeb tshaj yog cov roj cladding roj.
2, los ntawm "Armor" rau "Skeleton": Cov Ntawv Thov Tseem Ceeb ntawm Zirconium Alloy

• Core Daim Ntawv Thov: Roj Cladding Tube
  Qhov no yog qhov tseem ceeb tshaj plaws thov ntawm zirconium alloys. Nws yog zoo li "armor" ntawm nuclear roj pellets, ncig ib ncig ntawm uranium dioxide ceramactive cov tshuaj, thiab tswj cov xov tooj cua zoo nkauj flow raws. Nws qhov yuav tsum tau rau corrosion tsis kam, kev siv zog, creep tsis kam, thiab hluav taws xob kev loj hlob tau mus txog qhov huab.
• Kev Siv Ntxiv: Lwm cov txheej txheem txheej txheem
  Ntxiv rau Cladding Tubes, zirconium alloys tseem muaj dav nyob rau hauv cov khoom siv xws li cov tsiaj tswj hwm cov roj av) ntawm cov kev sibtaws roj. Hauv qee cov dej ua kom hnyav, zirconium alloys kuj tseem siv los tsim cov kav dej siab uas nqa cov qauv kev ua haujlwm tseem ceeb.

3, evolution thiab cov nyom: cov thev naus laus zis evolvution txoj kev ntawm zirconium alloys
Zirconium alloys tsis zoo li qub, thiab lawv cov thev naus laus zis tau ua kom tau raws li cov qauv kev nyab xeeb ntau dua thiab cov kev yuav tsum tau ua haujlwm

• Cov kev hloov kho ntawm cov khoom siv ntshiab: los ntawm cov tshuaj tiv thaiv kom ntxov, zr-are ® 2 (ZR-4 ®, M5 ® thiab Suav tus kheej tau tsim muaj alloys xws li N36. Lub cim tshiab ntawm zirconium alloys tau txhim kho tseem ceeb hauv kev txhim kho, thiab hydrogen embrittures los ntawm kev ntxiv cov ntsiab xws li niobium, tin, thiab hlau.
• Frontier tsom mus rau: Txhaum cov roj rau cov xwm txheej

Tom qab Fukushima kev sib tsoo, kev sib tsoo roj tau dhau los ua cov kev tshawb fawb thoob ntiaj teb thiab kev txhim kho hotspot. Ib qho ntawm nws cov tswv yim tseem ceeb yog ntxiv cov txheej tiv thaiv nyob rau saum npoo ntawm ib txwm muaj kev sib tsoo ntawm cov tshuaj tiv thaiv kev sib tsoo, thiab yuav lub sijhawm muaj txiaj ntsig zoo rau pov tseg kom muaj kev nyab xeeb. Qhov no sawv cev rau ib qho tseem ceeb rau kev thov yav tom ntej ntawm zirconium cov ntaub ntawv.
4, cov tsav tsheb ua lag luam thiab yav tom ntej
Tam sim no, muaj ntau yam yog ua ke tsav lub booming kev loj hlob ntawm cov qib no zirconium khoom lag luam:

• Tsav tsheb tsav tsheb yuam kev:

Cov phiaj xwm tshiab: hauv qab kev pom zoo thoob ntiaj teb ntawm cov phiaj xwm carbon neutrality, Tebchaws Europe, thiab lwm thaj chaw tshiab, thiab lwm yam kev xav tau zoo rau qhov siab-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Zoo siv cov ntaub ntawv zirconium.
Lub neej txuas ntxiv thiab rov qab los: Kev rov ua ntawv thov rau ntau lub zog ua lag luam tau txhais tau tias yog kev ua lag luam ntev dua thiab ua lag luam ruaj khov, muab cov ntaub ntawv thov kev txhawb nqa tau zoo rau zirconium cov ntaub ntawv.
Qhov nce ntawm SMR: Kev loj hlob thiab kev xa tawm ntawm cov modular cov tshuaj tiv thaiv me me tau coj cov khoom lag luam tshiab thiab cov kev lag luam rau zirconium khoom siv.

• Muaj saw hlau thiab zosization:

Nws yog tsim nyog sau tseg tias Tuam Tshoj tau ua tiav qhov sib txig tseem ceeb hauv kev ua haujlwm roj av, thiab muab cov khoom lag luam ruaj khov los ntawm kev tsim kho cov roj av thiab kev nyab xeeb ntawm lub teb chaws kev lag luam nuclear.

5, Txhawb lub neej yav tom ntej ntawm nuclear hwj chim nrog cov khoom zoo heev
Los ntawm kev ua kom muaj kev nyab xeeb thiab ruaj khov ua haujlwm ntawm cov reassing uas twb muaj lawm los txhawb kev ua haujlwm loj tshiab, cov tswv yim txuas ntxiv ntawm kev ua haujlwm siab tshiab ntawm kev ua haujlwm siab tshaj plaws. Nws qhov kawg nrhiav kev nyab xeeb, kev khwv nyiaj txiag, thiab kev ua tau zoo yuav txuas ntxiv tsav cov kev kawm ntawm cov ntaub ntawv tshawb fawb.

Hauv txoj kev taug kev no ntawm lub zog hluav taws xob kev ruaj ntseg thiab kev ua kom zoo thev naus laus zis zirconium cov khoom lag luam yog ua lub luag haujlwm tseem ceeb. Sawv cev los ntawm Shaanxi Zhongheng Weichuang, lub tuam txhab tau cog lus los muab cov neeg yuav khoom muaj kev ua haujlwm siab zirconium thiab cov kev daws teeb meem. Nws cov khoom nruj ua raws li cov kev paub tseeb nuclearance, nrog kev ntsuas ntsuas ntsuas cov qauv ntsuas kev ua haujlwm thoob ntiaj teb. Lawv tau ua tiav zoo nyob rau hauv ntau qhov kev ua haujlwm nuclear loj, muaj zog "rau kev nyab xeeb thiab kev txhim kho ntawm lub zog kev lag luam nuclear.
