EDF stoppt SMR-Projekt
Auch zweiter Versuch gescheitert
Von den Befürwortern der Atomindustrie wurde uns über Jahre versichert, dass Atomkraft wirtschaftlich nutzbar wäre, wenn es erst den "Small Modular Reactor" (SMR) geben würde. Handlich und sicher wäre das die Stromversorgung für mittlere energieintensive Unternehmen und Städte. Wie man das weiterhin ungelöste Atommüllproblem dabei bewältigt, wurde nicht erwähnt.
Interessant ist in diesem Zusammenhang, dass einige Internetgiganten wie Google und Microsoft kürzlich ankündigten, für die Stromversorgung ihrer KI-Labore eigene AKWs auf ihrem Firmengelände bauen zu wollen. Das wird mit SMR jetzt wohl nichts, deshalb will Microsoft in den kommenden Jahren einen Reaktor im stillgelegten fast-Supergau-US-Atomkraftwerk Three Mile Island wieder hochfahren lassen ...
Nun bleiben uns SMRs für die nächste Zeit erspart - d.h. natürlich nicht, dass nicht weiter Milliarden in ähnliche Projekte versenkt werden. Aber vor einem Jahr hatte bereits das US-Startup Nuscale sein SMR-Projekt beerdigt, weil es sich als zu teuer herausgestellt hat. Nun berichtet .ausgestrahlt:
Der staatliche französische Atomkonzern EDF hat nach vier Jahren Entwicklungsarbeit sein Projekt eines „small modular reactors" (SMR) wegen technischer Schwierigkeiten und ausufernder Kosten gestoppt. An dem Vorhaben der EDF-Tochter Nuward waren auch die Schiffsreaktorbauer und Rüstungskonzerne Naval Group und Technicatome, das französische Atomenergiekommissariat CEA, Framatome and Tractebel beteiligt.
Die Regierung hatte einen „Innovationszuschuss" von 500 Millionen Euro bewilligt, der Bau des Reaktors hätte 2030 starten sollen. EDF kündigte an, beim nächsten Versuch nur noch auf bereits verfügbare Reaktortechnik und -komponenten setzen zu wollen. Das Genehmigungsverfahren für das Reaktordesign muss dann neu aufgelegt werden.

Die 500 Millionen Euro "Innovationszuschuss" und mindestens ähnlich soviel eigenes Geld hat die wegen fehlenden Kühlwassers und ständigem Reparaturbedarf seiner AKW klamme EDF auf jeden Fall erst einmal erfolgreich versenkt. Mehr dazu bei .ausgestrahlt, Nr. 62, S.4 https://ausgestrahlt.de

The first small modular reactor in Romania will be installed on the land of the former thermal power plant in Doicesti, Dambovita County.
Can small modular nuclear plants be a part of renewable energy plans?
“Our results show that most small modular reactor designs will actually increase the volume of nuclear waste in need of management and disposal, by factors of 2 to 30 for the reactors in our case study,” said Lindsay Krall, the study’s lead author, in a release announcing the study results. “These findings stand in sharp contrast to the cost and waste reduction benefits that advocates have claimed for advanced nuclear technologies.” [...]
The study found that the smaller SMR design will experience more neutron leakage than a conventional reactor, affecting the amount and composition of waste streams. Neutron leakage is a term to describe neutrons escaping from the core, striking surrounding structural materials that then become radioactive. “The more neutrons that are leaked, the greater amount of radioactivity created by the activation process of neutrons,” Ewing said. “We found that small modular reactors will generate at least nine times more neutron-activated steel than conventional power plants. These radioactive materials have to be carefully managed prior to disposal, which will be expensive.”
NuScale will get the final approval nearly six years after starting the process.
Huge (pun intended)! Making a standard design constructed off-site will lead to huge cost benefits for licensing, construction, operation, and maintenance of future nuclear plants.
NuScale has more details on their website but the goal is that power plant facilities house 12 self-contained reactors that can provide "154 MWe to a mission critical facility micro-grid for 12 years without new fuel following a catastrophic loss of offsite grid and transportation infrastructure."
They estimate the cost of production for the n-th plant to be in the range "approximately $40/MWh to $65/MWh" and their first project has a contractual cap on costs at $58/MWh, all of which is price-competitive with large, established reactors like Diablo Canyon, though their small plant footprint generates a tenth of the electricity output.
They also support air-cooled designs, "which can reduce plant water consumption to as little as 1.1 gal/MWh" and the "high-temperature heat can be directly used to produce hydrogen through electrolysis, thus reducing efficiency losses". "Hydrogen produced by a NuScale HTSE system is forecasted to be cost competitive with high capacity factor renewable hydrogen cost estimates while also providing continuous, controlled hydrogen production."
Used fuel will be stored on-site:
NuScale reactor building and VOYGR plant design incorporates a proven safe, secure and effective used fuel management system. A stainless steel lined concrete pool holds used fuel for at least 5 years under 60 feet of water. The used fuel is protected both by the ground and the Seismic Category 1 reinforced concrete reactor building designed to withstand an aircraft impact, and a variety of natural and man-made phenomena.
After cooling in the spent fuel pool, spent fuel is placed into certified casks, steel containers with concrete shells, on site of the plant. The NRC Waste Confidence Rule states that this is a safe and acceptable way to store used fuel for an interim period at the plant up to 100 years. The NuScale's standard facility design includes an area for the dry storage of all of the spent fuel for the 60-year life of the VOYGR plant.
The plant also supports recycled fuel, or mixed uranium-plutonium oxide (MOX) fuel, helping to reduce nuclear waste.
“Энергоатом” и американская NuScale подписали меморандум о внедрении малых модульных реакторов в Украине
НАЭК “Энергоатом” и компания NuScale Power подписали Меморандум о взаимопонимании с целью изучения возможности строительства АЭС NuScale в Украине. Об этом сообщает пресс-служба “Энергоатома”. Согласно меморандуму NuScale будет оказывать поддержку компании по следующим вопросам: экспертиза технологии малых модульных реакторов (ММР), включая технико-экономическое обоснование предложенных площадок; разработка сроков и промежуточных результатов проектов; исследования затрат; технический анализ; […] Сообщение “Энергоатом” и американская NuScale подписали меморандум о внедрении малых модульных реакторов в Украине появились сначала на ANTIRAID. http://dlvr.it/S6nqQb
NuScale’s small nuclear reactor is first to get US safety approval
One hope buoying nuclear energy advocates has been the promise of “small modular reactor” designs. By dividing a nuclear facility into an array of smaller reactors, they can largely be manufactured in a factory and then dropped into place, saving us from having to build a complex, possibly one-of-a-kind behemoth on site. That could be a big deal for nuclear’s persistent financial problems, while also enabling some design features that further improve safety.
On Friday, the first small modular reactor received a design certification from the US Nuclear Regulatory Commission, meaning that it meets safety requirements and could be chosen by future projects seeking licensing and approval.
The design comes from NuScale, a company birthed from research at Oregon State University that has received some substantial Department of Energy funding. It’s a 76-foot-tall, 15-foot-wide steel cylinder (23 meters by 5 meters) capable of producing 50 megawatts of electricity. (The company also has a 60-megawatt iteration teed up.) They envision a plant employing up to 12 of these reactors in a large pool like those used in current nuclear plants.
