Chaw ntawm Amelikas Txoj Kev Lag Luam Nias Yam Nyuaj Ntaus
Thaum lub Peb Hlis 28, 1979, Ameskas tau ntsib kev phem tshaj plaws - muaj ib feem ntawm qhov reactor tseem ceeb ntawm Lub Ncauj Ncig Peb Ncig Hauv Chaw Noob Teb ze ntawm Middletown, Pennsylvania. Thaum lub sij hawm muaj teeb meem nrawm dhau los, cov ntawv tshaj tawm thiab cov lus qhia tsis sib haum ua rau ntshai, thiab ntau tshaj li ib puas txhiab tus neeg nyob hauv, feem ntau cov menyuam yaus thiab cov poj niam xeeb tub, khiav tawm thaj chaw.
- Thaum sawv ntxov hnub Lub Kaum Hlis 28, ob peb lub chaw dej txias tsis ua haujlwm nyob rau hauv qhov thib ob reactor ntawm Three Mile Island (TMI-2), ua rau lub reactor mus overheat.
- Lub reactor kaw nws tus kheej li yim seconds tom qab, tab sis cov tub ntxhais kub siab ntxiv mus nce vim tias kev tswj kav dej txias thaum muaj xwm ceev raug kaw.
- Kaum xya teev tom qab, tus tub ntxhais tau raug dej nyab kawg thiab nws qhov kev kub ntxhov coj los tswj hwm. Thaum lub sijhawm no, ib nrab ntawm cov tub ntxhais tau tawg, thiab ib feem ntawm nws tau tawg, txawm hais tias nws yog xyoo ua ntej cov kws tshawb fawb pom tau tias lub meltdown tau tshwm sim. TMI-2 tsuas yog ua haujlwm rau 90 hnub thaum muaj teeb meem tshwm sim.
- Thaum lub Peb Hlis 30, tom qab ntawd hu ua "Black Friday," xaiv tau hais txog kev tso tawm ntawm hluav taws xob thiab Pennsylvania tus thawj tswj hwm txiav txim siab ntawm cov menyuam thiab cov poj niam xeeb tub nyob hauv 5 mais ntawm tsob nroj. Tom qab ntawd, nws tau kawm tias qhov kev tso tawm tau npaj kom muaj kev ywj siab hauv lub cev.
- Thaum lub Plaub Hlis 2, 1979, tsib hnub tom qab lub meltdown, qhov teeb meem ntawm Peb Mais Island tau raug tshaj tawm tias yuav dhau mus.
- Txawm hais tias TMI-2 qhov kev tiv thaiv thiab cov ntaub ntawv xov tooj cua tsuas yog tsawg tshaj tawm, tus reactor tau hnyav heev. Tsis muaj leej twg nkag mus rau hauv cov nroj tsuag li ob xyoos.
- TMI-2 reactor yog qhov kawg ntawm lub pob zeb thiab TMI-1 yog rov pib dua xyoo 1986.
Kev cuam tshuam ntawm Peb Mile Island Cov Kev Puas Tsuaj
Ib qho kev sib xyaw ntawm cov khoom tsis ua hauj lwm, tib neeg yuam kev, thiab hmoov phem, qhov kev huam yuaj nuclear ntawm Peb Mais Island stunned lub teb chaws thiab tau hloov hlo nuclear kev lag luam hauv Tebchaws Asmeskas.
Txawm hais tias nws tsis muaj kev tuag los yog raug mob sai sai rau cov neeg ua haujlwm lossis cov neeg zej zog nyob ze, cov teeb meem TMI tau cuam tshuam rau nuclear kev lag luam - Nuclear Regulatory Commission tsis tau soj ntsuam ib daim ntawv thov kom tsim tau ib lub zog tshiab hluav taws xob txij li Tebchaws Meskas txij thaum ntawd. Nws tseem tuaj yeem hais txog kev hloov pauv ntawm kev npaj rau xwm txheej kub ceev, kev cob qhia tus neeg teb xov tooj, kev ua haujlwm rau tib neeg kev lag luam, kev tiv thaiv hluav taws xob, thiab ntau qhov chaw ntawm chaw ua haujlwm nuclear hluav taws.
Kev Noj Qab Haus Huv Ntawm Peb Mais Kob
Ntau cov kev tshawb fawb txog kev noj qab haus huv cov teebmeem, nrog rau kev tshawb fawb los ntawm University of Pittsburgh xyoo 2002, tau txiav txim siab nruab nrab cov koob tshuaj rau cov tib neeg ze ntawm Three Mile Island thaum lub sij hawm ntawm lub meltdown txog 1 millemem - ntau dua qhov nruab nrab, xyoo, natural background koob tshuaj rau cov neeg nyob hauv cheeb tsam hauv cheeb tsam Pennsylvania. Nees nkaum tsib xyoo tom qab, tsis tau muaj qhov loj hauv kev tuag ntawm cov neeg laus nyob ze ntawm qhov chaw Mile Island. Ib qho kev hloov tshiab ntawm kev txheeb xyuas kev soj ntsuam hauv thaj av ntawd ua los ntawm Radiation thiab Public Health Project, txawm li cas los, pom tias cov nqi tuag rau cov me nyuam mos, cov me nyuam, thiab cov neeg laus tuaj nyob hauv thawj ob xyoos tom qab Lub Ntiaj Teb Mile Island nyob rau hauv Dauphin thiab cov cheeb tsam ib puag ncig .
Peb Mile Island Hnub no
Niaj hnub no, TMI-2 reactor kaw ntiag tug thiab raug kaw, nrog lub reactant coolant system drained, dej tsis zoo thiab dej phom, cov khoom pov tseg pov tseg, xa mus rau qhov chaw pov tseg, cov roj reactor, thiab cov khib nyiab khib nyiab ntawm qhov chaw rau Lub Tsev Haujlwm Muaj Zog, thiab cov seem ntawm qhov chaw tau saib xyuas. Asmeskas, muaj kev sib tham txog kev rho tawm hauv chav 2 thaum nws daim ntawv tso cai xaus rau thaum lub Plaub Hlis 2014, tab sis cov kev npaj xa hauv 2013 los ntawm FirstEnergy, uas yog lub tsev 1, tam sim no hu rau "kev sib txuas lus ntawm lub tsev npav 2 nrog rau kev ua hauj lwm Phooj Ywg 1 thaum nws daim ntawv tsav tsheb nyob rau hauv 2034. " Lub decommissioning yuav muab qhov chaw dhau kaum xyoo, nrog rau tag nrho qhov chaw kho kom rov qab los ntawm 2054 - 75 xyoos tom qab qhov kev huam yuaj.
