Kev nce lub peev xwm ntawm cov reactors ntau lawm

Thawj pib, thawj Mayak reactor ua haujlwm nrog lub peev xwm ntawm 100 thermal MW. Txawm li cas los xij, tus thawj coj ntawm Soviet nuclear riam phom program, Igor Kurchatov, tau hais tias lub reactor yuav tsum khiav ntawm 170-190 MW nyob rau lub caij ntuj no thiab 140-150 MW nyob rau lub caij ntuj sov. Txoj hauv kev no tso cai rau lub reactor tsim yuav luag 140 grams ntawm plutonium muaj nuj nqis ib hnub.

Hauv xyoo 1952, kev tshawb fawb puv ntoob tau ua tiav txhawm rau txhawm rau ua kom muaj peev xwm ntau lawm ntawm cov reactors ua haujlwm los ntawm cov hauv qab no:

  • Los ntawm kev nce cov dej ntws siv los ua kom txias thiab ntws los ntawm thaj chaw nquag ntawm kev teeb tsa nuclear.
  • Los ntawm kev ua kom tsis muaj zog rau qhov tshwm sim ntawm corrosion tshwm sim nyob ze ntawm lub channel liner.
  • Txo tus nqi ntawm graphite oxidation.
  • Rising kub hauv cov roj hlwb.

Vim li ntawd, cov dej ntws ntawm cov dej ntws tau nce ntxiv tom qab qhov sib txawv ntawm cov roj thiab cov phab ntsa ntawm cov channel tau nce ntxiv. Peb kuj tau tswj kom tau tshem ntawm corrosion. Txhawm rau ua qhov no, peb xaiv cov aluminium alloy uas tsim nyog tshaj plaws thiab pib nquag ntxiv sodium bichromate, uas thaum kawg ua kom cov softness ntawm cov dej txias (pH los ntawm 6.0-6.2). Graphite oxidation ceased yog ib qho teeb meem ceev tom qab nitrogen tau siv los txias nws (yav tas los tsuas yog siv cua xwb).

Raws li xyoo 1950 tau ze, kev tsim kho tshiab tau muab tso rau hauv kev xyaum, txo qis qhov tsis tsim nyog ballooning ntawm uranium tshwm sim los ntawm hluav taws xob, txo cov cua sov ntawm uranium rods, txhim kho cladding kuj, thiab txhim kho kev tsim khoom.

Production at Mayak

"Chelyabinsk-65" yog ib qho ntawm cov chaw tsim khoom zais cia uas tsim riam phom-qib plutonium. Muaj ob peb lub reactors ntawm lub lag luam, peb yuav tau paub lawv txhua tus zoo dua.

Reactor A

Chav tsev tau tsim thiab tsim ua raws li kev taw qhia ntawm legendary N. A. Dollezhal. Nws ua haujlwm nrog lub zog ntawm 100 MW. Lub reactor muaj 1149 vertically teem tswj thiab roj raws nyob rau hauv ib tug graphite block. Tag nrho qhov hnyav ntawm cov qauv yog li 1050 tons. Yuav luag tag nrho cov channel (tshwj tsis yog 25) tau ntim nrog uranium, tag nrho cov huab hwm coj yog 120-130 tons. 17 channel tau siv rau kev tswj cov pas nrig thiab 8 rauua kev sim. Qhov siab tshaj plaws tsim hluav taws xob tso tawm ntawm cov roj cell yog 3.45 kW. Thaum xub thawj, lub reactor tsim txog 100 grams ntawm plutonium ib hnub twg. Plutonium hlau yog thawj zaug ua rau lub Plaub Hlis 16, 1949.

Technological flaws

Cov teeb meem loj heev tau txheeb xyuas yuav luag tam sim ntawd, uas muaj kev xeb ntawm aluminium liners thiab roj cell txheej. Cov uranium rods kuj o thiab tawg, thiab cov dej txias ntws ncaj qha mus rau hauv cov tub ntxhais ntawm lub reactor. Tom qab txhua qhov xau, lub reactor yuav tsum tau tso tseg ntev txog 10 teev kom qhuav cov graphite nrog cua. Thaum Lub Ib Hlis Ntuj xyoo 1949, cov channel liners tau hloov. Tom qab ntawd, lub community launch tau tshwm sim rau lub Peb Hlis 26, 1949.

Riam phom-qib plutonium, kev tsim khoom ntawm Reactor A tau nrog txhua yam teeb meem, tau tsim nyob rau lub sijhawm 1950-1954 nrog lub zog nruab nrab ntawm 180 MW. Kev ua haujlwm tom qab ntawm lub reactor pib nrog nws cov kev siv ntau dua, uas ib txwm ua rau kev kaw ntau zaus (txog 165 zaug hauv ib hlis). Yog li ntawd, thaum Lub Kaum Hli 1963, lub reactor raug kaw thiab rov pib ua haujlwm tsuas yog thaum lub caij nplooj ntoo hlav xyoo 1964. Nws ua tiav nws txoj kev sib tw xyoo 1987 thiab tsim 4.6 tons ntawm plutonium nyob rau tag nrho lub sijhawm ntawm ntau xyoo ntawm kev ua haujlwm.

AB Reactors

Nws tau txiav txim siab los tsim peb lub AB reactors ntawm Chelyabinsk-65 kev lag luam nyob rau lub caij nplooj zeeg xyoo 1948. Lawv lub peev xwm tsim tau yog 200-250 grams ntawm plutonium ib hnub. Tus thawj tsim ntawm qhov project yog A. Savin. Txhua reactor muaj 1996 raws, 65 ntawm lawv yog tswj raws. Ib qho kev tshiab tshiab tau siv hauv kev teeb tsa - txhua lub channel tau nruab nrog lub ntsuas cua txias tshwj xeeb. Qhov kev txav no ua rau nws muaj peev xwm hloov tau cov liners yam tsis tas yuav tsum ua haujlwm ntawm lub reactor nws tus kheej.

Thawj xyoo ntawm kev ua haujlwm ntawm cov reactors pom tias lawv tsim tawm txog 260 grams ntawm plutonium ib hnub. Txawm li cas los xij, txij li xyoo thib ob ntawm kev ua haujlwm, lub peev xwm tau maj mam nce, thiab twb nyob rau xyoo 1963 nws daim duab yog 600 MW. Tom qab lub thib ob overhaul, qhov teeb meem liners tau daws tag nrho, thiab lub peev xwm twb 1200 MW nrog ib xyoos ib zaug plutonium zus tau tej cov 270 kilograms. Cov ntsuas no tseem nyob mus txog thaum kaw tag nrho cov reactors.
