Weekly Nuclear Boomerang - Heti Nukleár Bumeráng

Week 31 (2025.07.28–2025.08.03) Nuclear Energy News Summary

Small Modular Reactors and Advanced Nuclear Technologies

The week marked significant progress in Small Modular Reactor (SMR) development, with several international partnerships forming. Fermi America partnered with South Korea's Hyundai Engineering & Construction to develop nuclear components for what is planned to be the world's largest private grid for next-generation AI applications[1]. This collaboration highlights the growing demand for nuclear power to support energy-intensive AI infrastructure.

Norway continued its nuclear expansion plans as Trondheimsleia Kjernekraft AS and Korea Hydro & Nuclear Power agreed to conduct a feasibility study for constructing a power plant using multiple Korean-designed i-SMR reactors in the municipalities of Aure and Heim[1]. This partnership demonstrates the increasing international cooperation in advanced reactor deployment.

Major Construction and Infrastructure Developments

China General Nuclear announced the installation of the bottom head containment vessel for unit 3 at the Taipingling nuclear power plant, marking another milestone in China's nuclear expansion program[1]. The country continues to lead global nuclear construction with multiple projects advancing simultaneously.

In the United States, BWX Technologies began fabrication of the reactor core for the Project Pele prototype mobile microreactor, the first microreactor to be built and operated in the US[1]. This represents a significant step toward deploying portable nuclear power systems for military and remote applications.

Nuclear Safety and Regulatory Developments

The International Atomic Energy Agency reported explosions and smoke near Ukraine's Zaporizhzhia Nuclear Power Plant on August 2nd, with an auxiliary structure being targeted[2]. The facility, located 1,200 meters from the plant perimeter, continued to emit smoke throughout the afternoon, highlighting ongoing nuclear security concerns in the conflict zone.

Japan provided the IAEA with reports on discharge records and seawater monitoring results at the Fukushima Daiichi Nuclear Power Station for April 2025[3]. The reports confirmed that radiation levels in sampled water remained substantially below operational targets set by TEPCO.

International Nuclear Cooperation

Ocean-Power and Copenhagen Atomics signed a memorandum of understanding to study the potential for producing electricity and heat in Norway using thorium-based molten salt reactors[1]. This partnership represents growing interest in alternative nuclear fuel cycles and reactor designs.

Russia and Niger signed a memorandum of understanding for cooperation on peaceful nuclear energy applications[1], expanding Russia's nuclear influence in Africa despite ongoing international sanctions in other sectors.

Nuclear Fuel Cycle and Waste Management

Slovakia and Urenco signed a contract for enriched uranium supply to the Bohunice and Mochovce nuclear power plants extending to the mid-2030s[4]. This agreement ensures continued fuel security for Slovakia's nuclear fleet.

China's largest uranium mining project successfully produced its first barrel of uranium products on July 12th, exactly one year after construction began[5]. The National Uranium No.1 demonstration project in Ordos uses CO2 and O2 in-situ recovery technology, marking China's entry into a new era of green, intelligent uranium extraction.

Fusion Energy Breakthrough

Helion Energy announced the beginning of construction work on its Orion fusion power plant in Malaga, Washington[1][6]. The facility will provide electricity to Microsoft, representing a significant milestone in commercial fusion energy development with operations planned by 2028.

31. hét (2025.07.28.-2025.08.03.) nukleáris energetikai hírek összefoglalója

Kis moduláris reaktorok és fejlett nukleáris technológiák

A hét jelentős előrelépést hozott a kis moduláris reaktorok (SMR) fejlesztésében, több nemzetközi partnerség jött létre. A Fermi America együttműködési megállapodást írt alá a dél-koreai Hyundai Engineering & Construction vállalattal nukleáris komponensek fejlesztésére, amely a tervezett világ legnagyobb magán hálózatának része lesz a következő generációs mesterséges intelligencia alkalmazások számára[1]. Ez az együttműködés kiemeli a nukleáris energia növekvő keresletét az energiaigényes AI infrastruktúra támogatásában.

Norvégia folytatta nukleáris bővítési terveit, miután a Trondheimsleia Kjernekraft AS és a Korea Hydro & Nuclear Power megállapodtak egy megvalósíthatósági tanulmány elkészítésében több koreai tervezésű i-SMR reaktor használatával Aure és Heim önkormányzatokban[1]. Ez a partnerség a fejlett reaktorok telepítésében folyó növekvő nemzetközi együttműködést demonstrálja.

Főbb építési és infrastrukturális fejlesztések

A China General Nuclear bejelentette a reaktortartály alsó fejének beépítését a Taipingling atomerőmű 3. egységénél, ami újabb mérföldkő Kína nukleáris bővítési programjában[1]. Az ország továbbra is vezeti a globális nukleáris építkezéseket több egyidejűleg haladó projekttel.

Az Egyesült Államokban a BWX Technologies megkezdte a Project Pele prototípus mobil mikroreaktor magja gyártását, amely az első, az Egyesült Államokban épített és üzemeltetett mikroreaktor[1]. Ez jelentős lépést jelent a hordozható nukleáris energia rendszerek katonai és távoli alkalmazásokhoz való telepítése felé.

Nukleáris biztonság és szabályozási fejlesztések

A Nemzetközi Atomenergia Ügynökség robbanásokat és füstöt jelentett az ukrajnai Zaporizszsjai Atomerőmű közelében augusztus 2-án, egy kiegészítő létesítményt értek találatok[2]. A létesítmény, amely 1200 méterre található az erőmű kerületétől, egész délután füstöt bocsátott ki, kiemelve a konfliktus övezetében fennálló nukleáris biztonsági aggodalmakat.

Japán jelentéseket nyújtott be az IAEA-nak a leeresztési rekordokról és a tengervíz-monitoring eredményekről a Fukushima Daiichi Atomerőműnél 2025 áprilisában[3]. A jelentések megerősítették, hogy a mintavételezett víz sugárzási szintjei jelentősen a TEPCO által meghatározott működési célértékek alatt maradtak.

Nemzetközi nukleáris együttműködés

Az Ocean-Power és a Copenhagen Atomics együttműködési megállapodást írt alá a tórium alapú olvadt só reaktorok használatával történő áram- és hőtermelés lehetőségeinek tanulmányozására Norvégiában[1]. Ez a partnerség a nukleáris üzemanyag-ciklusok és reaktortípusok alternatíváinak növekvő érdeklődését képviseli.

Oroszország és Niger együttműködési megállapodást írt alá a békés nukleáris energia alkalmazások terén való együttműködésről[1], bővítve Oroszország nukleáris befolyását Afrikában, annak ellenére, hogy más szektorokban nemzetközi szankciók vannak érvényben.

Nukleáris üzemanyag-ciklus és hulladékkezelés

Szlovákia és az Urenco szerződést írt alá dúsított urán szállítására a Bohunice és Mochovce atomerőművek számára a 2030-as évek közepéig[4]. Ez a megállapodás biztosítja Szlovákia nukleáris flottájának folyamatos üzemanyag-biztonságát.

Kína legnagyobb uránbányászati projektje sikeresen előállította első hordó urántermékeit július 12-én, pontosan egy évvel az építkezés megkezdése után[5]. Az Ordosban található Nemzeti Urán Szám 1 demonstrációs projekt CO2 és O2 in-situ kitermelési technológiát használ, jelezve Kína belépését a zöld, intelligens uránkitermelés új korszakába.

Fúziós energia áttörés

A Helion Energy bejelentette az építési munkálatok megkezdését Orion fúziós erőművén Malaga-ban, Washington államban[1][6]. A létesítmény áramot fog szolgáltatni a Microsoft számára, jelentős mérföldkövet képviselve a kereskedelmi fúziós energia fejlesztésében, a tervezett üzembe helyezéssel 2028-ban.
