China's Nuclear Expansion

China's nuclear sector continued its aggressive expansion with the State Council's previous approval of ten new reactors across five provinces gaining momentum[14][15][16]. The approved projects utilize primarily HPR1000 (Hualong One) technology, with some CAP1000 units, supporting China's goal of reaching 65 GW of nuclear capacity by 2025.

Magyar Nyelvű Összefoglaló: 29. Hét (2025. július 14-20)

Főbb Építkezési és Infrastrukturális Fejlesztések

Egyesült Királyság - Hinkley Point C Mérföldkő

Jelentős építési mérföldkövet ért el a brit Hinkley Point C atomerőmű a héten. A 2. blokk konténment kupolája sikeresen a helyére került, ezzel lezárultak a reaktorépületek főbb építőmérnöki munkálatai[1]. Ez kulcsfontosságú lépést jelent az Egyesült Királyság nukleáris energia reneszánsza felé, és folyamatos előrehaladást mutat Európa egyik legjelentősebb nukleáris infrastruktúra projektjén.

Kína Reaktor Építési Fejlődése

A kínai nukleáris projektek folytatták gyors fejlődési ütemüket több reaktor beépítéssel. A Liaoning tartományban található Xudabao atomerőműben beépítették az 1. blokk reaktor nyomástartályát, amely az egyik lesz a két CAP1000 reaktor közül[1]. Továbbá a Guangdong tartományban található Lufeng atomerőműben beépítették a 6. blokk belső konténment kupoláját, amely az első lesz a két épülő HPR1000 (Hualong One) egység közül[1].

Banglades Nukleáris Program Fejlődése

A bangladesi Rooppur atomerőmű újabb üzembehelyezési mérföldkövet ért el, amikor az első blokk megkezdte a forró tesztelési eljárásokat[1]. Ez a következő kritikus szakaszt jelenti Banglades első atomerőműve üzembe helyezésében, orosz VVER-1200 technológiával.

Egyesült Államok Nukleáris Politikai és Technológiai Fejlesztései

Fejlett Reaktor és Üzemanyag Ellátási Lánc Kezdeményezések

Az amerikai Energiaügyi Minisztérium jelentős kísérleti programot jelentett be a fejlett nukleáris reaktorok fejlesztésének felgyorsítására és a hazai nukleáris üzemanyag ellátási láncok megerősítésére[2][3][4]. A program kvalifikált amerikai cégeket keres nukleáris üzemanyag gyártósorok építésére és üzemeltetésére DOE engedélyezés alatt, az első jelentkezési határidő 2025. augusztus 15. Ez a kezdeményezés támogatja a szélesebb DOE erőfeszítést, hogy három fejlett reaktor design 2026. július 4-ig elérje a nukleáris kritikusságot.

Kis Moduláris Reaktor Fejlődés

Több SMR-rel kapcsolatos fejlesztés történt a héten. Az Oklo Inc kiválasztotta a Kiewit Corporation-t vezető kivitelezőként első kereskedelmi Aurora fejlett hasadási erőművéhez az Idaho Nemzeti Laboratóriumban[1]. A Kairos Power beépítette a reaktor edényt harmadik Mérnöki Teszt Egységéhez Oak Ridge-ben, Tennessee-ben, amely új gyártási technikák kipróbálására szolgál[1]. Továbbá az olasz Terra Innovatum Srl egyetértési megállapodást írt alá első SOLO mikroreaktorának Illinois államban történő telepítésére[1].

Zaporizsja Atomerőmű Incidensek

A Nemzetközi Atomenergia Ügynökség aggasztó katonai tevékenységről számolt be az ukrajnai Zaporizsja Atomerőmű közelében. Az üzemben állomásozó IAEA csapatok több száz kislövedékes lövést jelentettek, számos kis kaliberű töltény hüvelyt találtak az 5. és 6. reaktor egységek közelében[5][6]. Rafael Mariano Grossi főigazgató hangsúlyozta, hogy ilyen katonai tevékenység egy nagy atomerőműnél "egyértelműen elfogadhatatlan" és veszélyezteti a nukleáris biztonságot.

Nemzetközi Együttműködés és Finanszírozás

Világbank Nukleáris Energia Politikai Fordulat

Történelmi fejlemény történt a Világbank évtizedes nukleáris energia finanszírozási tilalmának megszüntetésével[7][8]. Ajay Banga Világbank elnök és Rafael Mariano Grossi IAEA főigazgató partneri megállapodást írtak alá azon országok támogatására, amelyek nukleáris energiát választanak fejlesztési stratégiájukba. Ez a politikai váltás új finanszírozási lehetőségeket nyit a fejlődő országok nukleáris projektjei számára.

Szabályozási és Gazdasági Fejlesztések

Amerikai Nukleáris Szabályozási Bizottság Frissítések

A Nukleáris Szabályozási Bizottság több szabályozási változtatást vezetett be a nukleáris fejlesztés egyszerűsítésére. Egy közvetlen végső szabály meghosszabbította a nukleáris reaktorok tervezési tanúsítványainak időtartamát 15-ről 40 évre, 2025. szeptember 15-i hatállyal[10]. Az NRC véglegesítette a 2025-ös pénzügyi évben alkalmazandó díjszabályt is, jelentős kedvezménnyel a fejlett nukleáris reaktor pályázók számára, óradíjat 148 dollárra csökkentve - több mint 50%-os csökkentés a korábbi díjhoz képest[11].

Technológiai és Innovációs Fejlődés

Fejlett Nukleáris Technológiák

Több technológiai fejlesztés haladt előre a héten. A Framatome megállapodást írt alá nukleáris üzemanyag egységek szállítására az UAE-beli Barakah Nukleáris Állomásra, amely az ellátási lánc diverzifikációs erőfeszítéseket képviseli[13]. Az USA folytatta a hazai nukleáris üzemanyag termelési kapacitások fejlesztését a külföldi forrásoktól való függés csökkentése érdekében, különösen a fejlett reaktor technológiák esetében[2].
