SINGAPORE (ICIS) – Kampani yamagetsi yaku Japan ya Tokyo Electric Power Co (TEPCO) yayambiranso ntchito zamalonda ku siteshoni yamagetsi ya nyukiliya ya Kashiwazaki-Kariwa (KK) Unit 6, nthawi yatsopano komanso yothandiza kwambiri poyesa kuchepetsa kufunikira kwa LNG mu gawo lamagetsi ku Japan pamene dzikolo likulimbana ndi mavuto atsopano omwe angakhalepo ndipo likuyang'ana njira zatsopano zopangira magetsi.
TEPCO idanena pa Epulo 16 kuti idayambiranso ntchito zamalonda pa 1.35GW boiling water reactor atalandira chitsimikizo cha kugwiritsa ntchito ndi satifiketi yoyendera kuchokera ku Japan's Nuclear Regulation Authority (NRA).
Kupanga kwa malonda kunayambiranso nthawi ya 4:00 pm nthawi yakomweko, zomwe zinali gawo loyamba la nyukiliya pamalo a KK kuyambira 2012 pambuyo poti malo onse opangira mphamvu za nyukiliya mdzikolo adatsekedwa motsatizana pambuyo pa ngozi ya malo opangira mphamvu za nyukiliya a Fukushima Daiichi omwe amayendetsedwa ndi TEPCO chifukwa cha tsunami yayikulu mu Marichi 2011.
Omwe akutenga nawo mbali pamsika adati kuyambiranso kwa KK Unit 6 - malo akuluakulu kwambiri a nyukiliya ku Japan ngati mayunitsi onse asanu ndi awiri adatha kupezeka pa intaneti, zomwe zikuwoneka kuti sizingatheke chifukwa cha Unit 7 yokha yomwe ingatheke chaka chimodzi kapena ziwiri zikubwerazi - zingachotse mwachindunji kupanga kwa gasi m'dera loperekera mafuta la TEPCO, makamaka nthawi ya mapewa ndi chilimwe pomwe kutulutsa kwa nyukiliya kumatha kugwira ntchito pazifukwa zambiri.
Ngati igwiritsidwa ntchito mokwanira, KK Unit 6 ikhoza kuchepetsa kuwotcha kwa LNG ponseponse poganiza kuti ikusintha mphamvu ya turbine ya mpweya yozungulira, amalonda ndi akatswiri akuyerekeza, ngakhale kuti kusamuka kwenikweni kudzadalira nthawi yozimitsira magetsi, kufunikira kwa gridi, ndi ndalama zotumizira kutentha.
Amalonda angapo adati kuyambiranso ntchito kumeneku kungachepetse kuchuluka kwa mafuta a LNG omwe amalowa ku Japan ndi katundu mmodzi kapena awiri pamwezi pachaka, poganiza kuti mphamvu ya nyukiliya ikuyenda bwino.
"Kuyambiranso kwa KK Unit 6 kumachepetsa kupsinjika kwa zofunikira pa mphamvu ya LNG kum'mawa kwa Japan," adatero wamalonda waku Japan. "Izi zikutanthauza kuti kupsinjika kochepa pa zosowa za LNG, ngakhale kuti gawo limodzi lokha silingawonekere mwachangu pakuchepa kwa kugula malo kapena kugulitsanso."
Koma ndi maphunziro omwe aphunziridwa kuchokera ku zopinga zowongolera, zovuta zamakina zoyambitsanso makina oyambitsanso ndi kupanga zinthu mogwirizana pambuyo pa zaka pafupifupi 14 osagwiritsa ntchito magetsi zomwe zimafotokoza nkhani yonse yoyambitsanso zida zina khumi ndi zisanu ndi zitatu za nyukiliya zomwe tsopano sizikugwira ntchito ndipo zingatheke kubwereranso kuntchito kumapeto, osatinso mafakitale atsopano a nyukiliya.
"Kuyambanso kuyambitsanso fakitale iliyonse ya nyukiliya ku Japan kumatanthauza misonkhano ya anthu onse, kuyang'anitsitsa malamulo ndi kuganizira zandale za m'madera osiyanasiyana," anatero katswiri wa zamagetsi ku Singapore.
"Tinaona zimenezo ndi KK; bwanamkubwa anayenera kusankha ndipo anakambirana mitundu yonse ya zokambirana. Koma mwina zochitika zosiyanasiyana zokhudzana ndi mphamvu zomwe zinachitika chifukwa cha tsunami ya mu 2011, nkhondo ya ku Ukraine komanso tsopano ndi Middle East - mfundo ndi malingaliro a anthu atha kukhala othandiza kwambiri."
Ndi KK, Japan tsopano ili ndi malo 15 opangira mphamvu za nyukiliya pa intaneti, ndipo kutengera kukonza ndi kugwiritsa ntchito mphamvu za nyukiliya, imatha kugwiritsa ntchito mphamvu za nyukiliya pafupifupi 33 GW, malinga ndi deta yaposachedwa kuchokera ku US Energy Information Administration (EIA).
Malo ena 24 opangira mphamvu za nyukiliya atsekedwa kwamuyaya.
NJIRA ZOTSATIRA
Kufunika kwa gasi ku Japan ndi nkhani yomwe ikukambidwa m'makambirano andale ndipo ikugwirizana ndi gawo lake lalikulu lopanga zinthu m'magalimoto amphamvu, sitima zoyendera ndi zomangamanga zamagetsi - ndi magwero amafuta obwezerezedwanso komanso omwe si a zinthu zakale omwe nthawi zambiri amakambidwa pokhudzana ndi njira zina zochotsera mpweya woipa monga kugwidwa ndi kusungidwa kwa mpweya woipa (CCS).
Pa nthawi ya nkhondo ya ku Iran, makampani otumiza mphamvu ku Asia konse, kuphatikizapo Japan, adagwiritsa ntchito mapulani achitetezo cha mphamvu omwe adawonetsa zizindikiro zomveka bwino za ogula LNG omwe achepetsa kale kugwiritsa ntchito, ogwiritsa ntchito akufunafuna njira yosinthira ku malasha ndi nyukiliya komwe kungatheke ndikuwonetsetsa kuti msika ukusunga ndalama zoyendetsera zoopsa zapadziko lonse lapansi.
Kuyambiranso kwa nyukiliya kumawonjezeranso mtengo wa TEPCO wopanga zida za nyukiliya, chifukwa kupanga zida za nyukiliya kumakhala kotsika mtengo kwambiri kuposa kupanga zida za LNG pogwiritsa ntchito mitengo ya mafuta ndi kaboni yomwe ilipo. Akatswiri akuyembekeza kuti kupezeka kwa zida za nyukiliya kudzawonjezera nthawi yotumizira mpweya ndi kufalikira kwa mphamvu za nyukiliya kum'mawa kwa Japan.
Kwa ogulitsa LNG, kubwerera kwa mayunitsi akuluakulu a nyukiliya kumabweretsa nkhawa yokhudza kusinthasintha kwa kufunikira kwa nthawi yayitali ku Japan, makamaka pamene kukonzanso mapangano kukulamulira zokambirana zogula kumapeto kwa zaka khumi, mkulu wa bungwe loyambitsa LNG adauza ICIS.
"Zikusonyeza kuti ngakhale zitseko zingapo zitabuka - dziko la Japan likhoza kukweza liwiro la mphamvu za nyukiliya pogwiritsa ntchito mphamvu zamphamvu za boma ndikuchepetsa kufunikira kwina."
M'zaka ziwiri zikubwerazi, kuyesa kuyambitsanso mphamvu za nyukiliya ku Japan kungathe kuwona kuti mayunitsi atatu akuluakulu ayamba kugwiritsidwa ntchito: Tomari‑3 (0.91 GW, Hokkaido Electric Power), Tokai Daini (1.16 GW, Japan Atomic Power Company), ndi Onagawa‑3 (0.83 GW, Tohoku Electric Power).
Kuyambiranso kwina kulikonse kopitilira izi kungakhale mu nthawi ya 2027-28 ndipo kuyenera kuonedwa ngati mwayi wabwino osati woyembekezeredwa.
Sitima yamagetsi ya Tohoku Higashidori Unit 1 (1.1 GW) ikadali pansi pa kuunikiridwa kwa NRA ndipo tsunami ndi zivomerezi zikukonzedwanso kwambiri, ngakhale kuti ikutchulidwa kuti ndi "kuyambiranso kwa mafunde otsatira".
Mofananamo, Shimane Unit 3 (1.37 GW Chugoku Electric) yatha, koma woyendetsayo wayika patsogolo kuyambitsanso Shimane‑2 kaye ndipo mavuto okhudzana ndi kutsata malamulo ku NRA amatanthauza kuti Unit 3 singakhale yoyambiranso isanafike chaka cha 2027.
Pakadali pano, Chubu Electric yachepetsa zolinga zoyambitsanso ndege ku Hamaoka posachedwa, komwe ma Units 3–5 (3.6 GW) sakugwira ntchito ngakhale kuti pali zovuta zambiri pambuyo pa chivomerezi cha Fukushima komanso mavuto okhudzana ndi chiopsezo cha tsunami ndi fault line, zomwe zapangitsa kuti kampaniyo ikhale patali ndi nthawi yomwe dziko la Japan likuyambanso kuyambitsanso ndege za nyukiliya.
