Tijekom posljednjih pet godina senzor koji bilje\u017ei emisije neutrona duboko u ru\u0161evinama nuklearne elektrane \u010cernobil pratio je postupni skok aktivnosti.<\/p>\n\n\n\n

Broj u porastu mo\u017eda nije ni\u0161ta. Mo\u017eda se \u010dak i spusti natrag, s obzirom na vrijeme. Znanstvenici nisu ba\u0161 voljni riskirati, jer se potencijal odbjegle reakcije nuklearnog cijepanja u budu\u0107nosti ne mo\u017ee isklju\u010diti dok ne znamo \u0161to se doga\u0111a.<\/p>\n\n\n\n

Na\u017ealost, precizno mjesto raspadaju\u0107eg materijala ispod ru\u0161evina i te\u0161kih betonskih plo\u010da \u010dini detaljna istra\u017eivanja i potencijalna rje\u0161enja gotovo nemogu\u0107ima i punima izazova.<\/p>\n\n\n\n

Tijekom desetlje\u0107a izotopi urana nastavili su ispu\u0161tati neutron iz svojih jezgri. Oni kojima se dogodi da se dovoljno pribli\u017ee jezgri drugog izotopa riskiraju naru\u0161iti vlastitu osjetljivu ravnote\u017eu, osloba\u0111aju\u0107i vi\u0161e neutrona.<\/p>\n\n\n\n

S obzirom na dovoljno visoku koncentraciju atoma, lan\u010dana reakcija izgubljenih neutrona mo\u017ee u kratkom vremenu generirati enormne koli\u010dine energije, s potencijalno eksplozivnim posljedicama.<\/p>\n\n\n\n

Neutroni izba\u010deni iz raspadaju\u0107e topline atoma urana obi\u010dno se kre\u0107u malo prebrzo da bi se lako uhvatili. Sve se to mijenja kada su neutroni prisiljeni prolaziti kroz odre\u0111ene medije, poput vode. Usporeni, imaju mnogo ve\u0107e \u0161anse da se zalijepe za jezgru i izazovu njezino vlastito propadanje. Imaju\u0107i ovo na umu, malo je iznena\u0111enje da stope cijepanja unutar FCM-a sko\u010de kad god se nakvase.<\/p>\n\n\n\n

Budu\u0107i da se emisije tako sporo pove\u0107avaju, rizik od prijetnji u bliskoj budu\u0107nosti \u010dini se niskim. Najgori scenariji tako\u0111er bi bili daleko od katastrofe 1986. godine.<\/p>\n\n\n\n

Ipak, s obzirom na osjetljivo, raspadaju\u0107e stanje FCM-ova \u2013 a smatra se da soba naziva 305\/2 sadr\u017ei oko polovice izvornog goriva reaktora \u2013 \u010dak i mala eksplozija mogla bi eksplodirati radioaktivni otpad dovoljno daleko dodatno kontaminira prostor nekoliko desetaka kilometara oko elektrane.<\/p>\n\n\n\n

U planu je \u010di\u0161\u0107enje goriva, privremeno skladi\u0161te trenutno \u010deka dozvolu ukrajinskog regulatora. Za sada se malo mo\u017ee u\u010diniti no ostaje nada da \u0107e se brojke ipak smiriti same od sebe.<\/p>\n\n\n\n
