SINGAPORE (ICIS) – Ikigo cy’amashanyarazi cy’Abayapani Tokyo Electric Power Co., TEPCO, cyongeye gusubukura ibikorwa by’ubucuruzi kuri sitasiyo y’amashanyarazi ya kirimbuzi ya Kashiwazaki-Kariwa (KK) Unit 6, ikaba ari umwanya ukomeye kandi w’ingenzi mu bikorwa byo kugabanya ikenerwa rya LNG mu rwego rw’amashanyarazi mu Buyapani mu gihe igihugu kirimo guhangana n’ibibazo by’ingufu nshya zishobora guterwa no gushaka andi masoko mashya.
Ku ya 16 Mata, TEPCO yavuze ko yongeye gutangiza ibikorwa by'ubucuruzi kuri 1.35GW nyuma yo kubona icyemezo cyo kubikoresha mbere y'uko bikoreshwa ndetse n'icyemezo cyo kugenzura Ikigo gishinzwe kugenzura ikoreshwa ry'ibinyabutabire mu Buyapani (NRA).
Gutunganya ubucuruzi byasubukuwe saa yine z'umugoroba ku isaha yo muri ako gace, bikaba ari byo bya mbere ishami rya kirimbuzi rikorera muri KK kuva mu 2012 nyuma y'uko inganda zose z'ingufu za kirimbuzi mu gihugu zifunzwe nyuma y'impanuka y'uruganda rwa kirimbuzi rwa Fukushima Daiichi rukorera muri TEPCO yatewe na tsunami ikomeye muri Werurwe 2011.
Abitabiriye isoko bavuze ko kongera gutangiza KK Unit 6 - ikigo kinini cyane cya kirimbuzi mu Buyapani iyo ibisate byose birindwi bibasha kujya kuri interineti, ibyo bikaba bisa nkaho bitashoboka kuko Unit 7 ari yo yonyine ishoboka mu mwaka umwe cyangwa ibiri uri imbere - byakuraho uburyo butaziguye umusaruro ukoresha gazi mu gace k’ibicuruzwa bya TEPCO, cyane cyane mu bihe by’impeshyi aho umusaruro wa kirimbuzi ushobora gukora ku bintu byinshi bifatika.
Mu gihe ikoreshejwe neza, KK Unit 6 ishobora kugabanya ubushyuhe bwa LNG muri rusange dukoresheje gusimbuza ikoreshwa rya turbine ya gaze ihuza imikorere, nk'uko abacuruzi n'abasesenguzi babiteganya, nubwo kwimura imikorere bizaterwa n'igihe cyo guhagarara, ubusabe bw'umuyoboro w'amashanyarazi, n'ubukungu bwo kohereza ubushyuhe.
Abacuruzi benshi bavuze ko gusubukura indege bishobora kugabanya ibicuruzwa bya LNG by’Ubuyapani ku mutwaro umwe kugeza kuri ibiri buri kwezi buri mwaka, bitewe n’uko umusaruro wa nyukliya uhagaze neza.
Umucuruzi w’Umuyapani yagize ati: “Gutangiza KK Unit 6 bigabanya igitutu ku bisabwa ku mutwaro w’amashanyarazi kuri LNG mu burasirazuba bw’Ubuyapani. Ibi bivuze ko igitutu gito ku bikenewe kuri LNG, nubwo kimwe muri byo gishobora kutagaragara vuba mu kugabanuka kw’ibiciro cyangwa ibikorwa byo kongera kugurisha.”
Ariko amasomo twize mu mbogamizi zishingiye ku mategeko, uburyo ikoranabuhanga ryo kongera gutangiza icyuma gitera ingufu z’amashanyarazi n’uburyo gikoreshwa n’abafatanyabikorwa nyuma y’imyaka hafi 14 kidakora neza, ni byo bivuga inkuru yagutse ku kongera gutangiza izindi mashini cumi n’umunani za kirimbuzi ubu zitakora neza kandi bishoboka ko zishobora kongera gukoreshwa ku rwego rwo hejuru, tutibagiwe n’inganda nshya za kirimbuzi.
“Kwimura kongera gutangiza uruganda urwo arirwo rwose rukora ibikoresho bya kirimbuzi mu Buyapani bivuze ko hagomba kuba ibiganiro rusange, igenzura ry’amategeko n’ibitekerezo by’ingenzi bya politiki mu karere,” nk’uko byatangajwe n’umusesenguzi w’ingufu muri Singapuru.
“Twabibonye kuri KK; Guverineri yagombaga gufata icyemezo no kujya mu nama z’ubwoko bwose. Ariko wenda urukurikirane rw’ibibazo by’ingufu byatewe na tsunami yo mu 2011, intambara ya Ukraine ndetse n’ubu hamwe n’Uburasirazuba bwo Hagati – politiki n’imyumvire ya rubanda bishobora kuba byiza kurushaho.”
Hamwe na KK, Ubuyapani bufite inganda 15 za kirimbuzi kuri interineti, kandi bitewe n’uburyo bwo kubungabunga no gukoresha neza, bushobora gukoresha ubushobozi bwa kirimbuzi bugera kuri 33 GW, nk’uko amakuru aherutse gutangwa n’Ikigo gishinzwe gutanga amakuru ku ngufu muri Amerika (EIA) abigaragaza.
Izindi nganda 24 z'amashanyarazi za kirimbuzi zafunzwe burundu.
INTAMBWE ZIKURIKIRA
Ubusabe bwa gazi mu Buyapani buri mu biganiro mpaka kuri politiki kandi bufitanye isano n’urwego runini rw’inganda mu bijyanye na gari ya moshi zitanga ingufu, ubwikorezi bw’ubwato n’ibikorwa remezo by’ingufu - aho amasoko ya lisansi akomoka ku bikomoka ku bimera n’ibitari ibya kera akunze kuvugwaho mu bijyanye n’izindi gahunda zo gukuraho karuboni nko gufata no kubika karuboni (CCS).
Mu ntambara ya Irani, abatumiza ingufu muri Aziya, harimo n'Ubuyapani, berekeje ku migambi y'umutekano w'ingufu yagaragaje ibimenyetso by'uko abaguzi ba LNG basanzwe bagabanya ikoreshwa ry'amashanyarazi, abakoresha ingufu bashaka inzira yo kuzungukiramo amakara n'ibinyabutabire aho bishoboka no gushyira isoko mu bikorwa bigamije gutuma inyungu y'ingufu za politiki ikomeza kwiyongera.
Gutangiza ikoreshwa rya lisansi ya kirimbuzi kandi binongera ikiguzi cya TEPCO cyo gukora, kuko umusaruro wa lisansi ya kirimbuzi uhendutse cyane ugereranije n’ikoreshwa rya lisansi ya kirimbuzi ikoreshwa na LNG hakurikijwe ibiciro bya lisansi na karuboni. Abasesenguzi biteze ko ikoreshwa rya lisansi ya kirimbuzi ryiyongera rizagira ingaruka ku masaha yo kohereza lisansi ikoreshwa na lisansi n’ikwirakwira ry’ibishashi mu burasirazuba bw’Ubuyapani.
Ku bagurisha LNG, kugaruka kw'ingufu nini za kirimbuzi bitera impungenge ku bijyanye no kugabanuka kw'ibikenewe mu Buyapani mu gihe kirekire, cyane cyane ko kuvugurura amasezerano ari byo byiganje mu biganiro byo gutanga amasoko mu mpera z'iki mwaka, nk'uko umuyobozi ushinzwe ishyirwaho rya LNG yabibwiye ICIS.
“Bigaragaza ko nubwo hazabaho inzitizi nyinshi – Ubuyapani bushobora kongera umuvuduko w’ingufu za kirimbuzi binyuze mu gushishikariza guverinoma cyane no gukuraho bimwe mu bisabwa.”
Mu myaka ibiri iri imbere, imbaraga zo kongera gukoresha ingufu za kirimbuzi mu Buyapani zishobora gutuma ibice bitatu by'ingenzi bitangira gukoreshwa: Tomari 3 (0.91 GW, Hokkaido Electric Power), Tokai Daini (1.16 GW, Japan Atomic Power Company), na Onagawa 3 (0.83 GW, Tohoku Electric Power).
Kongera gutangira bundi bushya birenze ibi birashoboka cyane ko bizagwa mu gihe cya 2027-28 kandi bigomba gufatwa nk'ibintu byiza aho kuba ibintu bigoye kwitega.
Imodoka ya Tohoku Higashidori Unit 1 (1.1 GW) iracyari mu isuzumwa rya NRA, aho tsunami nyinshi n'imitingito bikomeje kuvugurura, nubwo bivugwa ko ari "izongera gutangira".
Mu buryo nk'ubwo, Shimane Unit 3 (1.37 GW Chugoku Electric) yuzuye mu buryo bwa tekiniki, ariko ikigo cy’amashanyarazi cyashyize imbere gutangiza Shimane 2 mbere ya byose kandi ibibazo byo gukurikirana muri NRA bivuze ko Unit 3 idashoboka ko ari yo itangira gukora mbere ya 2027.
Hagati aho, Chubu Electric yahagaritse intego zo kongera gutangiza indege za Hamaoka mu gihe gito, aho indege zo mu bwoko bwa Units 3–5 (3.6 GW) zikomeje kutagira aho zihuriye n’akazi mu gihe habayeho igenzura rikomeye nyuma y’imitingito ya Fukushima ndetse n’inzitizi z’amategeko ku bijyanye n’ibyago byo kwangirika kw’imirongo y’amazi n’ibyago bya tsunami, ibi bikaba byarasize ikigo cy’amashanyarazi mu gace k’Ubuyapani kigiye kongera gutangiza indege za kirimbuzi.
