"Fukushima-1": tsaona uye nemigumisiro yayo

The tsaona panguva "Fukushima-1" kwakakonzerwa nokudengenyeka kwenyika uye kwakatevedzana Tsunami. Roga, ravarwi aiva kumucheto uye chaizoita kutsungirira mumwe rwokuzvarwa chiito.

By tsaona kwakaguma chokuti iri chirimwa yakadhirika maviri chete dzinongoitika dzoga. Nokuda kwenyika patsanura chikuru simba yemapurisa, pakarepo pashure kusanganisira zvashata emagetsi, asi naivowo havana vakashanda kwenguva refu nemhaka Tsunami.

tsaona Zvinokonzera

NPP "Fukushima-1" akanga avaka 70s remakore rapfuura uye panguva tsaona nyore isashande. Project simba renyukireya chirimwa hakurevi nedzidziso kuvapo netsaona utariri zvishandiso yaizova kunze basa.

Uye kana kwepasi chiteshi akamira, Tsunami, sezvataurwa pamusoro apa, mashoko NPP akasiya pasina magetsi.

Pamberi tsaona, aishanda anokwana zviyero zvitatu, uye vakanga vasara pasina kutonhora, sezvo mugumisiro - the coolant pamwero rakadonha, asi kumanikidza kuti akatanga kusika chiutsi, zvakanga nekusiyana, kuwedzera.

Kukura njodzi rakatanga yokutanga chikwata. Kuti reactor haisi kukuvadzwa nokuda yakakwirira kumanikidzwa chiutsi pauri kuti germooblochku asarudza. Asiwo kufurirwa yakawedzera nokukurumidza mairi.

Zvino kuti uchengeteke akatanga chiutsi pauri zvakananga mumhepo. It vakakwanisa kuramba containment, asi rehydrogen, iyo yakaumbwa nokuda denudation peturu leaked obstroyku reactor mupanda.

Zvose izvi zvakaita kuti kuputika yokutanga simba chikwata. Zvino zuva pashure kwenyika yose 12 March. The kuputika zvishoma akaparadza chesamende mamiriro, asi reactor mudziyo haisi zvaparadzwa.

zviitiko

Mushure Kuputika Unit kwazvo kwevari nemwaranzi, asi maawa mashomanana akadonha. On mundima NPP "Fukushima-1" ivhu vakatorwa, uye netsvakurudzo kuvapo necesium. Izvi zvaireva kuti tightness yacho reactor raputsika.

Kuchitonhora kuti reactor akatanga kupomba mvura mugungwa. Zuva rakatevera Zvakazoitika kuti yechitatu chinogumbura wakaremara wegadziriro zvashata kutonhora. Uyewo pane fungidziro kuti mafuta zvinhu zviri zvishoma pachena, uye anogona zvakare kuitika kuputika rehydrogen.

Takatanga kusiyira yegwara containment uye kupomba yomugungwa. Asi hazvina kubatsira, uye kwaiva kuputika musi 14 March. Zvisinei, reactor mudziyo haana kukuvara.

Ramba basa riri kudzorerwa magetsi wokutanga uye wechipiri zvinogumbura. Uyewo akaramba kupomba mvura wokutanga uye wechitatu zvinogumbura.

Pazuva iroro vakaramba nechimbichimbi kutonhora maitiro uye yechipiri simba chikwata. Mutange kupomba yomugungwa kuti kutonhora. Asi pakarepo kuputswa vharafu kusunungura hwemvura uye pumped mvura ndokuva zvisingabviri.

Asi njodzi iyi, "Fukushima-1" haana rapera. Kuputika ari simba yechipiri vachiri aiva mangwanani March 15th. Pakarepo raputika kuchengetera renyukireya mafuta panguva simba wechina. Moto kudzima chete pashure maawa maviri.

March 17 mangwanani vakatanga kusiyira yomugungwa pamwe helicopters kutigumbura Pools 3 uye 4. Mushure Diesel chiteshi akakwanisa kudzosera wechitanhatu chinogumbura, zvaigoneka kupomba mvura achishandisa pombi.

tsaona kubviswa

Kuti tsvimbo hurongwa vakava operative, zvaida kudzoreredza magetsi. Uye nokuda kwayo kupora zvakanga zvakakodzera kupomba mvura kubva nemafashamo turbine nehoro.

All kuoma ndechokuti padanho nemwaranzi mumvura yakanga yakakwirira zvikuru. The mubvunzo akasimuka: apo kupomba kubuda mvura. Kuti izvi zvidaro, takasarudza kuvaka tsvina kurapwa chirimwa.

The boka, iyo muridzi "Fukushima-1", akati kuti aizofanira kurasikirwa matani 10 kwemvura shoma nemwaranzi mugungwa kusunungura kukwira vanokwanisa kuti zvikuru radioactive mvura kubva pakutanga matatu renyukireya simba dzakabatana.

Maererano nepurani, kubviswa migumisiro yakakwana achatora makore anenge makumi mana. Nuclear reactors rakavharwa pasi, uye vakatanga kubvisa aipedza mafuta renyukireya kubva madziva. Pave paya, "Fukushima-1" dismantling zvenyukireya reactors rakakwana zvinofanirwa.

zvakazokonzerwa tsaona

paiva nemwaranzi vhinza Somugumisiro zvose zviitiko. The Hurumende aifanira kununura vanhu kubva 20-kiromita mapazi akapoteredza chirimwa. Vanokurudzirwa kutizira avo vaigara 30 chete kubva renyukireya simba chirimwa "Fukushima-1".

Japan, "Fukushima-1" nemakapoteredza kwakasvibiswa radioactive okunze. Vanewo kuwanikwa mvura yokunwa, mukaka uye dzimwe zvigadzirwa. Rate aiva pasi bvumidzwa, asi nokuda kuvimbiswa kwavo kushandisa kwenguva duku kurambidzwa.

Takabatwa nemwaranzi mu yomugungwa uye ivhu. Mune dzimwe nyika yakawedzera kumashure nemwaranzi.

Kuwedzera kushatiswa kwezvakatipoteredza, pane zvemari nezvinhu. Tersa Company vanosungirwa varipe kuti vawirwa netsaona.

"Fukushima-1" nhasi

Nhasi, simba renyukireya miti mberi liquidating basa. In May 2015 pakava vhinza pamusoro radioactive mvura. Uyewo hazvina anoramba rokuchenesa mvura rakabviswa zvidhinha.

Uyu ndiwo mumwe matambudziko makuru. Zvikuru mvura radioactive zvakawanda, uye muitiro kutonhora zviri reactors, chinotova. Zvinonzi pumped kuva inokosha pevhu reservoirs, zvishoma nezvishoma kuchena.
