Power Start-Up Underway at New Power Unit 6 of Leningrad NPP

The power start-up at the Leningrad NPP Unit 6, containing ROSATOM’s flagship Generation III+ VVER-1200 reactor, has begun following the green light from Russia’s watchdog Rostekhnadzor. Power start-up comprises a complex series of stages over the course of which reactor’s power is gradually increased from 1% to 35-40%. That power level generates sufficient energy to turn on the turbogenerator, which, when connected to the grid, then begins producing electricity – a milestone scheduled for this autumn.

The commissioning of Leningrad NPP Unit 6 began on 19 July 2020, when the first assembly with fresh nuclear fuel was loaded into the reactor core prompting the unit’s physical launch. During physical start-up, nuclear scientists successfully brought the reactor to a power level of about 1% and confirmed that the unit’s physical characteristics comply with those stipulated in its design. The scientists also evaluated the efficiency and reliability of the reactor’s security systems and safety interlocks.

The Unit 6 is expected to enter commercial operation in 2021. It will replace Leningrad NPP Unit 2 equipped with RBMK-1000 reactor, which has successfully operated for 45 years.

Core Catcher Vessel Installed at Akkuyu NPP Unit 2

Installation of the core catcher vessel into design position has been completed in the Reactor Building of Power Unit 2 of the Akkuyu NPP. The height of the core catcher shell is 5.8 metres, diameter 6.1 metres, weight 169 tonnes. The vessel being the main part of the core catcher is a tank, which, in case of an emergency, will securely hold core melt within the sealed volume of the Reactor Building and prevent it from leaking in the environment. It is partially filled with a special material, which allows stopping chain reaction immediately and keeping core melt stable.

The next important stage in construction of Unit 2 reactor building will be installation of the first tier of inner containment into design position.

Cantilever truss shall provide protection of core catcher vessel and communications in hypothetical case of core melt-down. It is also designed for arrangement of communication lines - water supply, steam discharge, pass-through of communications for measurement instrumentation. Cantilever truss structure also provides special corridors for "catcher" inspection.

By virtue of the core catcher Akkuyu NPP shall be protected from any severe accidents. Previously, a similar "core catcher" has been installed at Akkuyu NPP Unit 1. These devices are used in modern nuclear power plants of Russian design with generation "3+" VVER-1200 nuclear reactors. The core catcher has maximum safety characteristics: increased seismic resistance, hydrodynamic and shock strength, flood protection and simplified installation technology.

Installation Time Reduced for Foundation Pit at Rooppur NPP

Engineering Division specialists have applied the Russian Sheet-Pile Walls, abbreviated as RShS in Russian, technology in constructing foundation pit retaining structures for water intake structures and for the feed pump station at the Rooppur NPP construction site in Bangadesh.

Russian Sheet-Pile Walls are a construction kit featuring a ready-made range of standard solutions based on sheet piles with beams as reinforcing members. Other technical solutions for foundation pit retaining structures like, for instance, a slurry-wall technology, were unsuitable for the Rooppur NPP construction site due to the complex hydrogeological conditions. That is why the Technology Transfer Center of the Engineering Division proposed that an RShS technology, selected and added to the industry-wide Database of Best Available Technologies, be implemented at the Rooppur NPP.

As compared to similar sheet-pile structures like, for instance, tubular sheet piles (abbreviated as TSh in Russian), the RShS technology boasts such advantages as a simplified assembly process at the construction site and high stability at low costs. It takes less time to drive piles for RShS in comparison with TSh which is a great advantage in the context of constructing an NPP. Thanks to the RShS high stacking density, logistics costs can be reduced. This solution allows you to reduce the installation time for retaining structures to a value of up to twice as low, and to cut the costs of works and materials by about 30%.

With a view to successfully implementing the said technology, the TTC has formed a technological alliance involving Aquatic JSC, GK Profil Ltd. and Orgenergostroy Institute JSC and interacting with the Nizhny Novgorod Design Institute, a branch office of the Atomenergoproekt JSC, for design issues. Such a formation has made it possible to unite experience and competencies of the members by creating a continuous process chain ranging from the design to the implementation.

Rosatom Submits Hanhikivi-1 NPP Design to Fennovoima Oy

ROSATOM’s RAOS Project Oy, the plant supplier of Hanhikivi-1 NPP, has submitted the Basic Design Stage 1 documentation package containing technical solutions description to Fennovoima Oy, the NPP Customer. The package has been reviewed by Fennovoima’s specialists and conditionally accepted for further work. The Basic Design Stage 1 package comprises the main stages of documentation development for the creation of the NPP design. In accordance with the EPC contract, the submitted package includes description of such key areas as conceptual and functional NPP design, 3D model, NPP systems and buildings design.

The newly submitted design documentation provides the basis for the Preliminary Safety Analysis Report, which shall be reviewed and accepted by the Finnish Radiation and Nuclear Safety Authority before the construction license is granted by the Finnish government.

Consisting of 15 batches, PSAR is the main document of the license application. It presents a detailed description of all safety-related aspects: NPP site selection, basic design and technical solutions, safety measures, as well as the results of design validations from a safety point of view.

To date, five PSAR batches have already been submitted by the Customer to STUK for review. The goal of RAOS Project is to deliver two more batches of documents to Fennovoima before the end of this year and to complete the Preliminary Safety Analyses Report in spring 2021.

STUK requirements in terms of the detailing level of documents at licensing stage are higher if compared to most other countries. This high level of detail at the construction license stage provides advantages for further project stages, avoiding delays and saving the need for works to be re-designed after the actual construction started.

Vattenfall Ringhals 1 Nuclear Reactor Shuts Down

The nuclear power plant, Ringhals 1, was shut down as planned on New Year’s Eve. After nearly 45 years of power operation, the nuclear fuel will now be removed from the reactor, after which the plant will be prepared for decommissioning. Ringhals 1 was put into commercial service on 1 January 1976 and at the time of its final shutdown was estimated to have delivered 220 terawatt hours of electricity, which corresponds to the whole of Gothenburg’s consumption of electricity during the same period.

Even though both Ringhals 1 and 2 have now been shut down, electricity generation at Ringhals continues with the Ringhals 3 and 4 reactors. These reactors have been equipped with independent core cooling, an investment of SEK 900 million and a regulatory requirement to continue operations after the turn of the year. Ringhals 3 and 4 provide approximately 12 percent of the country’s electricity generation, previously the four reactors combined answered for around 20 percent of Swedish electricity generation.

Robot Tested at Leningrad Nuclear Power Plant

A unique robot assigned with the task of performing diagnostics and repair of the wall lining and bottom of the cooling ponds of VVER-1200 reactor-enabled units was tested at the Leningrad NPP. The robotics device was constructed specifically for servicing new types of nuclear power plants. Additional operations like draining water from the pool or unloading fuel in order to operate the NPP are no longer required, unlike the current way of NPP operation. The distinguishing feature of the robot is its versatility: it looks for potential leaks, determines their coordinates, cleans up the defective surface and performs plating of the surface by welding. Its repair modules are equipped with swivel brackets. This allows for work in any hard-to-reach areas of the pool, for example, in the corners.

The device was tested at a special stand, where experts simulated the entire chain of operations it needs to perform. The robot is ready for operation in the storage pools of Leningrad NPP Units 5 and 6.

The spent fuel pool is a reinforced concrete structure with a metal cladding filled with water with boric acid. The storage cassettes with spent nuclear fuel are stored for several years until heat dissipates and radioactivity levels decrease.

De kern van kernenergie
Kernenergie is in Nederland een beladen onderwerp. Maar zo nu en dan popt het omhoog. Tijd om de plussen en minnen op een rij te zetten.

19-11-2020
Kernafval
In deze editie van de rubriek Duurzaam Dilemma van ASN Bank kijken we kritisch naar de plussen en minnen van deze energiesoort en haar plek in de energiemix.

We schrijven niet vaak over kernenergie, omdat het met slechts één werkende kerncentrale (die in het Zeeuwse Borssele) voor de meeste lezers waarschijnlijk een ver-van-mijn-fornuis-show is. In de herfst kwam dit onderwerp weer wat dichterbij toen Minister Wiebes bekendmaakte dat hij kernenergie wel degelijk als een ‘serieuze optie’ ziet in de toekomstige ‘energiemix’.

Hoe werkt kernenergie eigenlijk?
Voor alle lezers die niet vooraan zaten in het natuurkundelokaal eerst nog even een korte uitleg. Een kerncentrale maakt met stoom stroom. De vrijkomende stoom laat turbines met een dynamo draaien en die genereren elektriciteit. En hoe ontstaat die stoom? Niet door verbranding (zoals in een klassieke energiecentrale op steenkool) maar door atoomsplitsing.

Nog even terug naar de kern: wat is een atoom? Dat zijn de piepkleine ‘legosteentjes’ waar mensen en dieren, maar ook tafels en zware metalen uit bestaan. In 1934 ontdekte Enrico Fermi, een Italiaanse uitvinder, dat het zware metaal uranium zeer geschikt was om energie mee op te wekken. Een wereldoorlog en wat jaren verder werd in 1956 in Engeland de eerste kerncentrale geopend. Ruim 60 jaar later zitten we nu ongeveer 440 kerncentrales in circa 30 landen actief.

Kernenergie: de plussen
Bij het opwekken van kernenergie komt geen CO2 vrij. De grondstoffen uranium en in de toekomst wellicht thorium zijn nog volop aanwezig. En voor kernenergie is relatief weinig vierkante meters nodig. Dus geen grote windparken op zee of zonneparken op land.

En de veiligheid dan? Na de kernrampen in Harrisburg (1979), Tsjernobyl (1986) en Fukushima (2011) hebben ingenieurs hard gewerkt aan het verbeteren van de veiligheid. Volgens ontwerpers is de kans op een zeer ernstig ongeluk met de huidige veel moderner kerncentrales nu eens in de miljoen jaar.

In elektriciteitsscenario’s voor Europa wordt kernenergie vaak genoemd. Naast zon en wind en overige bronnen als biomassa en gascentrales met CO2-opslag. Als uitgangspunt van deze scenario’s geldt dat de energiebron betaalbaar moet zijn en geen CO2 uitstoot.

Kernenergie: de minnen
Het prijskaartje van een nieuwe kerncentrale bedraagt zo’n € 10 miljard. Maar dit bedrag kan makkelijk veel hoger uitvallen. Dat bleek bij de bouw van nieuwe kerncentrales in Finland en Engeland.

Wie gaat dit financieren, is de grote vraag. Banken zitten niet te wachten op dit soort langlopende, financieel lastig voorspelbare projecten. Energieproducenten zijn voor het merendeel in buitenlandse handen en staan ook niet te springen. En de staat? De grote vraag is of de Nederlandse overheid financieel wil bijspringen.

Wist je dat een kerncentrale pas rendabel is als er meer dan 90% van de capaciteit wordt benut? Nederland focust zich de afgelopen jaren vooral op wind- en zonne-energie en bij deze energievormen is vooral aanvullende elektriciteit nodig. Voor als er geen zon of wind is.

Protest bij de kerncentrale in het Zeeuwse Borssele

Een kernramp heeft grote gevolgen in geld en oppervlakte. In 2011 lekte een Japanse kernreactor in Fukushima (Japan) radioactief materiaal nadat een Tsunami de centrale had platgelegd. Een groot gebied moest worden ontruimd en 10 jaar later is gebied van 370 km2 (zo groot als onze 5 Waddeneilanden) nog steeds verboden terrein. Het opruimen van de schade vindt nog steeds plaats en gaat een geschatte 1000 miljard dollar kosten, de prijs van 100 nieuwe kerncentrales.

Ook een bekend bezwaar is het kernafval dat kernenergie met zich meebrengt. Opslag van kernafval diep onder de grond zal technisch best mogelijk zijn maar is het ook veilig? Het hoogactieve afval blijft wel meer dan 100.000 jaar lang gevaarlijk. Is het fair om dat voor talloze generaties na ons te beslissen?

Tot slot is de verwachting dat duurzame energietechnieken als zon, wind, waterkracht en geothermie de komende tien jaar nóg goedkoper gaan worden en dat ook de opslag van elektra uit die bronnen haalbaar en betaalbaar wordt. Hebben we die dure kerncentrale dan nog wel nodig?

Tot slot
Heb jij een mening over kernenergie? Bij ASN Bank volgen we de ontwikkelingen op de voet en zien we kernenergie niet als een duurzame oplossing. Investeren in kernenergie doen we dus niet.

Waarom kunnen we ons kernafval niet de ruimte in schieten. Van een kerncentrale komt niet meer als een zeecontainer vol radioactief afval. Lang niet meer zoveel als vroeger. Schiet het in een raket naar de zon zou ik zeggen, dat is een grote kernreactor op zichzelf. Jammer dat mensen zich zo stuk staren op fouten van vroeger. Kijk eens de serie chernobyl zou ik zeggen, als je ziet wat daar aan vooraf allemaal fout ging dan snap je dat dit tegenwoordig toch niet meer gebeurd.

PIK Neutron Reactor Put into Energy Operation Mode

PIK neutron reactor was put into power operation at the National Research Center Kurchatov Institute in St Petersburg Institute of Nuclear Physics on February 8, the Day of Russian Science. The unique features of neutron radiation make it a universal method for interdisciplinary research in biology, materials science, medicine, the study of archaeological artefacts, etc. Neutron scattering techniques are already used in many areas of natural science, but their use in the adatomic studies and high molecular weight structures in biology, biophysics and condensed matter physics is one of the most dynamically developing. Thus, a neutron source gives science in any country a unique research tool. A mega-installation such as a neutron or synchrotron light source is designed not just for a single institute, but also for the joint use of all scientists from Russian and foreign scientific centers.

The Russian government made a decision to create an International Center for Neutron Research in the field of nuclear physics, medicine, materials science, nanobiotechnologies at the site of the Kurchatov Institute. Some of the experimental stations are being created jointly with German colleagues. The commissioning of the PIK research reactor complex will provide a significant increase in Russia’s share in the world markets for the provision of high-tech services for the use of neutron and nuclear methods in the development of new materials, products and technologies, including for biomedicine. The new complex will make it possible to carry out large-scale neutron research not only by scientists from Russia and the CIS countries, but also from other foreign countries. In today’s scientific landscape of Russia, the commissioning of the PIK reactor will further strengthen our country’s leading position in the field of megascience.
