From 06 through to 15 July, a SALTO* peer review mission of the International Atomic Energy Agency (IAEA) was held. It reviewed the activities for ensuring long-term operation (LTO) of Units 5 and 6.
The mission team implemented a thorough review of the documentation, and during working meetings with experts and managers of the nuclear power plant discussed the activities in the review areas of “Organization of ageing management and LTO activities”,“ Scope setting, plant programmes and corrective action programmes”, “Ageing management of mechanical SSCs”, “Ageing management of electrical and I&C SSCs”, “Ageing management of civil SSCs”, and “Human resources, competence and knowledge management for LTO”.
The review team, composed of experts from the Czech Republic, Spain, Slovakia, and UAE, together with three IAEA representatives, found good performance that will be shared with the international professional community. Suggestions were made for further improvement of the activities implemented for safe long-term operation.
The Chief Executive Officer of Kozloduy NPP appreciated highly the IAEA support for the nuclear power plant pointing out that the results from this mission would contribute for enhancing the activities that ensure the safe operation of Units 5 and 6 in the extended lifetime period.
The IAEA Team Leader, Gabor Petofi, noted that Kozloduy NPP staff demonstrated professionalism, openness, and receptiveness to the suggestions for improvement, and that the measures for safe LTO were performed in a timely manner and in compliance with the IAEA safety standards.
This SALTO mission was preceded by two pre-SALTO missions – one on Unit 5, in 2016, and one on Unit 6, in 2018.

Set to begin commercial operations soon, it will supply 1,400MW power to national grid.
Abu Dhabi: The UAE is the first Arab country with a functional power plant. By the end of this month, its Barakah Nuclear Power Plant is set to begin commercial operations.
When the plant is complete, the electricity it produces without generating any carbon will be able to power more than half a million UAE households for a whole year. These 5,600 megawatts of clean electricity will prevent the release of 21 million tonnes of carbon emissions every year, which amounts to the carbon absorbed by 350 million trees over ten years.
Already, the plant’s first Unit has been connected to the UAE national grid. This is a big deal: The UAE — an energy producer that has historically relied on carbon-producing fossil fuels for its energy needs — is setting the lead for a clean energy future, even in a world facing economic setbacks as a result of the COVID-19 pandemic.
Located in Abu Dhabi’s Al Dhafra area, the Barakah plant is owned by the Emirates Nuclear Energy Corporation, and operated by Nawah Energy Company. Its activities are overseen by the Federal Authority for Nuclear Regulation (FANR).
In 2020, the first of its four units was connected to the grid. At the same time, FANR granted the operating licence for Unit 2 on Tuesday. Eventually, the plant will supply 25 per cent of the UAE’s peak electricity demand.
“It is historic that the UAE is the first Arab country in the region to operate a nuclear power plant, and it is the culmination of 13 years of effort in building such a programme. This milestone was achieved due to the UAE’s vision and its leadership to build a peaceful nuclear energy programme to cater for the future needs of energy in the country,” said Hamad Al Kaabi, UAE Permanent Representative to the International Atomic Energy Agency (IAEA) and FANR deputy chairman.
Ahead of the plant’s commercial operations, here are all the important facts to know about the UAE’s journey towards the peaceful use of nuclear energy.
What is nuclear fuel made of?
Uranium is a naturally occurring, mildly radioactive element that fuels many nuclear energy plants. Uranium-235 is an isotope, or form, of the element that can undergo fission, the process of splitting an atom. This makes it an ideal fuel for nuclear reactors.
How is nuclear fuel made?
Just like oil and coal, the material for nuclear fuel, called uranium ore, comes from underground. It is found in mines in nearly 20 countries around the world. After it is mined, uranium ore goes through several processes. This includes separating it from other substances, changing it into a material that is usable for nuclear fuel, and manufacturing fuel pellets.
The fuel pellets are about the size and shape of a pencil eraser or an adult fingernail. They are loaded into metal tubes. These tubes, called fuel rods, are about four meters long. When bundled together, the rods create a fuel assembly.
How much fuel does a nuclear reactor use?
A nuclear reactor can use more than 200 fuel assemblies at one time, depending on the design. The APR-1400, the reactor design used at Barakah, operates using 241 fuel assemblies. Each fuel assembly weighs about 650kg.
What happens during fuel load?
Fuel load is the safety-led process that involves filling a nuclear reactor with uranium, the fuel that is used as a source of heat to generate electricity. As part of the Fuel Load process, Nawah’s expert operators and fuel handlers transferred 241 fuel-assemblies, one-by-one, into the reactor. With safety being the overriding priority at every stage, the carefully planned task took roughly 14 days to complete. With all the fuel assemblies loaded, the reactor vessel at Unit 1 of the Barakah Plant contains 241 nuclear fuel assemblies. Each pellet contains enough energy to produce electricity for one Emirati household for up to four months, with zero carbon emissions.
Is fresh fuel radioactive?
New fuel assemblies have a low level of radioactivity. A person can stand next to a fuel assembly without threat to their health. During the process of manufacturing of fuel assemblies, workers wear special gloves to protect the tubes and components of the assembly from the oils and moisture which accumulate on a person’s skin. When they are brought to the site, fuel assemblies are transported in specially designed shipping casks. These casks are secure and robust, and made primarily of stainless steel. They are designed to protect the fuel from damage during transport.
Is used nuclear fuel radioactive?
Used fuel is highly radioactive. Countries around the world have safely transported and stored used fuel for decades. Carefully designed containers are used to store and to transport used fuel, and prevent the release of radioactive material into the environment. The UAE is committed to ensuring the implementation of the highest international standards of quality and safety when handling used nuclear fuel to protect employees, the public and the environment. Does nuclear fuel need to be replaced?
Each fuel assembly can last up to six years in a reactor. Workers replace the fuel assemblies when they no longer produce enough heat. They replace about one-third of a reactor’s fuel every 12 to 24 months. At Barakah, refuelling will take place every 18 months but engineers are working to improve the efficiency of the reactor and the fuel being used in order to move to a 24-month operating cycle. This will ensure the reliable delivery of continuous and clean electricity to the UAE for two years before a reactor has to be shut down to be refuelled.
What happens to nuclear fuel once it is removed from a reactor?
Once it is removed from a reactor, used nuclear fuel is stored in concrete and steel-lined pools located adjacent to the reactor building for about five years. Cool water circulates through the pools to remove heat from the fuel until it is cool enough to move to long-term storage or to reprocess.
What happens after the used fuel is cool?
When the used fuel is cool, it is moved to concrete and steel containers called dry casks. These casks can be securely stored on-site at a nuclear energy plant or at an interim or long-term storage facility. As part of its commitment to nonproliferation, the UAE decided to forgo reprocessing from the start of the nation’s peaceful nuclear energy programme.
How does a nuclear plant work?
A nuclear plant uses uranium as fuel to generate heat. The heat makes steam, which spins a turbine connected to a generator, producing electricity.
Where does the heat come from?
Inside the nuclear fuel assemblies, there are fuel pellets made of uranium. One pellet is the size of a fingernail, but it contains the same amount of energy as one ton of coal, or 471 litres of oil. Uranium is a special element and has an interesting property — if it absorbs a small particle called a neutron, it will split into two lighter elements, releasing a lot of heat together with more neutrons. This process is called fission. The new neutrons then hit more uranium atoms, which split, releasing more heat and neutrons and so on. This is called the chain reaction and it goes on and on by itself.
Doesn’t this process go out of control?
No, because in a nuclear plant, workers control the reaction by using special equipment that absorbs neutrons. In this way, the number of neutrons absorbed by the uranium is limited, thus limiting the amount of heat generated as well. This also means that the plant workers, known as reactor operators, can completely stop the reaction, and safely shut the reactor down.
So, what is reactor startup?
Reactor startup is when the chain reaction is launched. It is the first time a neutron is sent to a uranium atom, which releases heat and more neutrons. The reaction is then allowed to continue, increasing the amount of heat inside the reactor.
What is grid synchronisation and connection?
Grid synchronisation or grid connection, is a historic moment for any energy plant. This marks the first time that the electricity produced at the plant is delivered to the national grid. To do this, the plant’s operators and engineers bring the electric generator to the same conditions as the electric grid, allowing the two to connect safely.
How does grid connection happen in a nuclear plant?
In a nuclear energy plant, grid connection happens in the same way as in any gas, coal or oil-fired plant. The equipment and process for grid connection are all the same. The main difference with any fossil-fuelled plant is that a nuclear plant uses uranium pellets as fuel to generate heat, which creates steam that spins a turbine, which in turn drives the electric generator to produce electricity. This process creates zero CO2 emissions.
To connect a nuclear plant to the electrical grid, the reactor operators slowly increase the heat generated by the reactor to generate enough steam to begin spinning the turbine and driving the generator. Once the reactor is at about 15 per cent power, enough steam is created to have the turbine spinning at its optimal speed. This allows the electric generator to prepare to synchronise and connect to the national electricity grid.
What happens next?
Following the successful startup of the reactor and then the grid synchronisation and connection of unit’s generator, the plant operators slowly increase reactor power and electrical output. This process is called Power Ascension Testing (PAT). Numerous tests are conducted at different power levels, ensuring that all equipment is performing safely and as designed. This process takes several months to complete, until the unit reaches 100 per cent reactor power.
ENEC has already answered common questions about nuclear safety.
Are nuclear energy plants safe?
Yes. The performance records of approximately 450 nuclear energy facilities operating in more than 30 countries have demonstrated that nuclear energy is safe.
The World Association of Nuclear Operators tracks data about plant performance, including safety system performance, fuel reliability and industrial accident rates. The performance data consistently show positive results.
In the UAE, the FANR plays an essential, and entirely independent role in ensuring that the Barakah Nuclear Energy Plant is safe, secure and reliable through robust regulation and oversight.
The Barakah plant follows international best practices and uses a defence-in-depth safety approach. This includes:
— Multiple physical barriers that protect against accidental radiation release.
— Multiples layers of redundant and diverse plant safety systems which ensure that the reactor operates normally and shuts down automatically if necessary.
— The emergency response plan, which is regulated, tested and exercised with FANR, and has been reviewed by the International Atomic Energy Agency (IAEA)
Does the UAE have any plans to enrich uranium for its own fuel?
No. It is enshrined in the UAE Nuclear Law that the UAE will not enrich uranium, and this is reinforced in the UAE Policy on the peaceful use of nuclear energy. Following a comprehensive procurement process, ENEC entered into contracts with six suppliers to provide materials and services, including uranium enrichment. KEPCO Nuclear Fuels (KNF) in South Korea fabricates the fuel assemblies which are then shipped to the UAE following all regulations and international best practices.
Will the UAE reprocess used nuclear fuel?
No. In addition to forgoing domestic enrichment, another part of the UAE’s commitment to nonproliferation is to forgo the reprocessing of nuclear fuel.
The UAE is a signatory of all relevant international agreements and treaties for nonproliferation, and is a member of the relevant organizations and regimes. The UAE also signed a 123 Agreement with the United States of America, which incorporates nonproliferation commitments.
What will the UAE do with the fuel once it is removed from a reactor?
The Federal Government of the UAE is developing its long-term storage policy for spent fuel, but ENEC must ensure the safe disposal of solid radioactive waste in accordance with the laws of the UAE and the legislation of the Federal Authority for Nuclear Regulation and the International Atomic Energy Agency.
The UAE is a signatory of the IAEA Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management, and submits a regular report to the organisation to describe its efforts on the steps taken to fulfil its obligations as a Contracting Party to the Convention.
The UAE is well ahead in developing its plans, with storage needs not required for at least two decades, as the Barakah plant can safely store waste for the first 20 years of operations.
Note: The IAEA is the global body that facilitates cooperation in the field of nuclear energy.
The Federal Authority for Nuclear Regulation (FANR) was established in 2009 as an independent nuclear regulator. Its mandate is to ensure the safe, secure and peaceful use of nuclear and radiation activities in the UAE.
Mission: The FANR works to protect the public and the environment from the harmful effects of ionising radiation.
Workforce: More than 245 people work at FANR, including 67 per cent Emirati and 41 per cent of women. Its nuclear experts hail from 31 different countries, and possess a strong nuclear safety, security and nonproliferation record.
Standards: The FANR built a robust regulatory system based on international standards, including IAEA best practises and standards followed in United States, Canada and South Korea.
Barakah Nuclear Power Plant
This is the first nuclear power plant in the UAE, and in the Arab World.
Location: It is located in Al Dhafra area in Abu Dhabi emirate, 280 kilometres away from the capital city.
The nuclear power plant will produce electricity to cover 25 per cent of the UAE’s peak energy needs when fully completed.
The electricity generated through the plant will help prevent the release of 21 million tons of carbon emissions annually.
FANR is responsible for regulating the design, siting, construction, operation and decommissioning.
The Emirates Nuclear Energy Corporation (ENEC) was established in 2009 to construct the plant.

What’s the risk of an accident like TMI, Chernobyl, Fukushima happening at Barakah?
The Barakah plant has implemented lessons learned from Three Mile Island and Chernobyl. Post-Fukushima, the APR1400 design used at Barakah underwent a significant review using the European Stress Test method. This method determined that the plant design was already fairly robust against Fukushima-type events. To ensure this, FANR integrated the lessons learned from Fukushima into the requirements for the construction of the Barakah plant and reported on their implementation to the IAEA in 2017.
The event will take place on Friday, February 19, 2021, from 14:00 to 16:00.
The round table will be held in English and in Bulgarian with translation provided through the platform zoom webinars.
Together with representatives of companies from the industry, institutions and non-governmental organizations will discussed the main challenges and opportunities for the development of nuclear technologies in Bulgaria.
