Hpa Majaw Nuclear Wan Hkrun Lam Nkau Hta Cooling Tower N Nga Ai Kun?

 

 

 

I.Cooling Ladat gaw Cooling Tower ni ra kadawn ai lam hpe dawdan ya ai

 

Nuclear wan jak langai a core cooling ra ai lam gaw, nbung turbine kaw na pru wa ai nbung a n kaja ai nbung hpe shapraw kau na matu re. Cooling system ni hpe masum hku garan nna:kalang-katsi ai hku nna, pat da ai-loop bai shinggrup ai katsi ai, Htenbung katsi ai. Katsi ai nta ni hpe pat da ai-loop bai shinggrup ai katsi ai jak ni hta sha lang ai.

 

 

 

2.Pat da ai-loop bai shinggrup ai katsi ai (katsi ai nta ni ra ai)

 

Hka n law ai majaw pat shingdang hkrum ai mungdan kata na Nuclear wan jak ni gaw, .hka shinggrup ai + katsi ai ntamode. Hka shinggrup ai gaw condenser ni hta katsi ai hpe hkap la nna, katsi ai hpe shapraw kau na matu hte katsi ai hpe shayawm kau na matu, hka lim ai hku nna katsi ai hpe shayawm kau na matu, hka hpe bai jai lang na matu bai lwi wa ai hpang, hka hpe n jahten kau lu ai. Mungdan kata na Nuclear wan jak masing ni (ga shadawn, Europe hte America mungdan ni hta nga ai mungdan kata na Nuclear wan jak nkau mi) hta, masat da ai hkrang masa hku nna, katsi ai nta ni hpe jung da ra ai.

 

3.Nbung katsi ai ladat (htunghking katsi ai nta n ra ai)

 

Katsi katsang re ai shara ni hta nga ai wan jak nkau mi gaw, nbung hte nbung galai shai ai arung arai ni a lapran hkrak (sh) n hkrak hkra matut mahkai ai lam hku nna, nbung katsi ai hpe direct (sh) indirect air cooling hku nna jai lang ma ai. Ndai ladat gaw nbung n-gun yawm ai lam n lawm ai sha, katsi ai nta ni hpe mung n ra ai, raitim, nbung galai shai ai atsam yawm ai hte nbung galai shai ai shara kaba ni hte fan n-gun grau law hkra jai lang ra ai.

II. Mungdan hte Hka Hpawk Masa ni a Madung Hkrun Lam

 

1.Hka hkin gau/hka hkin gau-htingbu shara ni a akyu ara

 

Panglai hka hte hka hkin gau hka law law gaw, hka lum ai hku nna kalang- hka lu la ai hte hka pru ra ai hpe hkap la lu ai majaw, katsi ai nta npawt ni hpe n ra sai. Ya aten hta Miwa mungdan hta bungli galaw nga ai Nuclear wan jak yawng gaw panglai hkin-gau makau kaw nga ai majaw, katsi ai nta ni hpe madung hku nna n jung da ai.

 

2.Lamu ga kata/hka-n law ai shara ni a pat shingdang ai lam ni

 

Inland ginra ni hta hka n law ai hpe hkrum sha nga ai. Kalang -hkang nna katsi ai hpe grup yin makawp maga tara ni hte hka n-gun hpe shadawn sharam ai hku nna pat shingdang da ai majaw, pat da ai-loop recirculating katsi ai hpe ra sharawng ai hku lata la ra ai, katsi ai nta ni hpe dai hku nna madang masat da ai daw langai byin wa ai. Ga shadawn, Amerikan hte France mungdan ni hta nga ai lamu ga kata na Nuclear wan jak ni yawng hta, hyperboloid cooling tower kaba ni hpe lang da ai.

III. Reactor amyu hte Coolants ni a shai hkat ai lam ni

 

Cooling system design ni gaw reactor amyu myu hta n bung ai, reactor amyu nkau mi gaw shingra tara hku nna htunghking hku nna katsi ai nta ni hpe n ra ai.

 

Reactor amyu	Katsi ai	Katsi ai arawn alai	Katsi ai Tower ra ai lam
Hka hpe n-gun dat dat ai jak (PWR)	Hka n-gun kaba -	Primary hte secondary loop ni hpe garan tawn da ai; Lahkawng ngu na loop gaw nbung pru ai wan hpe katsi shangun ra ai	Kalang lang-katsi ai hku nna lang ai panglai hkin-gau hpun ni a matu n ra ai; pat da ai-loop katsi ai hpe lang nna lamu ga kata na hpun ni a matu ra ai
Hka lum ai jak (BWR)	Hka	Dai coolant gaw direct hku nna hka lim nna steam pru wa ai; Hka pru ai wan n-gun hpe shayawm kau ra ai	Kalang lang-katsi ai hku nna lang ai panglai hkin-gau hpun ni a matu n ra ai; pat da ai-loop katsi ai hpe lang nna lamu ga kata na hpun ni a matu ra ai
Sodium-katsi ai lawan ai n-gun dat jak	Ntsin sodium	Liquid metal gaw katsi ai hpe galai shai ya lu ai atsam kaba hpe jaw ya ai; Evaporative katsi ai lam n ra ai	Madung hku nna htunghking hku katsi ai nta n ra ai
Tsaw-Katsi ai Gas-Katsi ai Reactor	Helium	Gas hpe katsi ai hte katsi ai hpe galai shai ai hku nna katsi ai hpe shapraw kau ai	Htunghking hku nna katsi ai nta n ra ai
Thorium- hpe madung tawn ai Hka Hku Hkrun Lam	Hka lum ai sau	Molten sau hpe katsi shangun ai; system design gaw katsi ai hpe shapraw kau na matu hka n-gun n ra ai	Htunghking hku nna katsi ai nta n ra ai

 

 

 

 

IV.Hkringmang daju a grup yin makawp maga lam hte sut masa lam ni a lapran na sut masa-off

 

1.Grup yin hpe hkan sa ai lam

Kalang-katsi ai hku nna hka pru ai hka n-gun hte nbung n san seng ai lam hte seng nna grup yin masat masa ni hpe hkan sa ra ai. Hka hkin gau ginra ni hta hka htung kaba ni nga ai majaw, hkan sa ra ai lam ni hpe hkan sa na matu loi ai. Inland closed-loop recirculating katsi ai gaw grup yin tara ni hpe hkan sa na matu katsi ai nta ni hku nna katsi ai hpe hkang ai.

 

 

2.Sut masa

Once-through cooling gaw, n law ai capital gawgap ai manu hte bungli galaw ai manu ni hpe madun dan ai raitim, hka npawt nhpang a majaw pat shingdang ai lam ni nga ai. Closed-loop recirculating cooling galaw na matu gaw, hka lim ai nta ni hpe gawgap ra ai, dai hta gumhpraw law law bang ra ai raitim, hka n law ai shara ni hta gaw htuk manu ai. Nbung katsi ai ladat ni gaw hka-hpe hkye la ai raitim, fan n-gun law law jai lang ai majaw, aten galu-bungli galaw na matu manu grau law hkra jai lang ra ai.

                                                

laksan mabyin masa ni hte hkrang shapraw ai lam hpe grau kaja hkra galaw ai

 

1.Nuclear n-gun n-gun jat ai lam (sanghpaw/hka kata sanghpaw)

Laksan shara n law ai majaw, n-gun n law ai katsi ai ladat (ga shadawn, panglai hka hpe kalang-katsi ai hku nna, n-gun ja ai-katsi ai nbung galai shai ai jak ni hte kayau kaya galaw ai) hpe jai lang ai, katsi ai nta ni hpe n jung da ai.

 

2.Kaji ai n-gun dat jak (SMR)

Nkau design ni gaw, nbung katsi ai (sh) nbung katsi ai hpe hpawng de da ai majaw, dai ladat hpe asan sha galaw ya nna, katsi ai nta kaba ni hpe n ra sai.

 

Ngut nna tsun ga nga yang, Nuclear wan jak langai hta katsi ai nta ni hpe bang na kun ngu ai gaw, katsi ai ladat, ginra masa, reactor hkrang shapraw ai lam, sut masa lam ni hpe madung tawn nna, hkum tsup ai hku dawdan ra ai. Coastal once- hku nna katsi ai ladat ni, laksan reactor amyu myu (ga shadawn, sodium-katsi ai lawan ai reactor ni, n-gun ja ai-katsi ai gas-katsi ai reactor ni), nbung katsi ai ladat ni gaw htunghking hku katsi ai nta ni hpe n ra ai, lamu ga kata de pat da ai re}lo circulating{7 katsi ai nta ni. Nuclear n-gun hpe lamu ga kata hte hka-n law ai shara ni de jat wa ai hte maren, katsi ai nta ni hpe jai lang ai lam grau nna chyam bra wa na re. Dai aten hta, nbung hpe katsi shangun ai hpaji masa ni hte reactor amyu nnan ni mung, katsi shangun ai ladat hpe gyin shalat ai lam hpe amyu myu hku nna shabyin ya nga ai.
