The BWRX-300 is the latest, tenth generation of BWR designs developed by GE Hitachi Nuclear Energy. The technologies used in this reactor have proven reliability in previous generations of reactors and the newer solutions have been licensed by the US Nuclear Regulatory Commission (NRC). It is a small modular reactor with an electrical capacity of 300 megawatts, using naturally circulating water cooling (pumps are not required for reactor safety). Passive safety systems have been used to keep the reactor in a safe condition in all circumstances without human intervention.<\/p>

The construction of the first\u00a0builds the reactor<\/a> Ontario Power Generation in Canada, and will enter commercial operation between 2027 and 2028.<\/p>

The same type of reactor can be built in Estonia once all the necessary nuclear safety requirements are in place, a national regulator is in place to oversee the construction of the plant, and the first reactor under construction in Canada is completed.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Smaller<\/strong>\u00a0\u2013 The BWRX-300 station fits on a land area of 170 x 280 meters. The grid connection switchyard, cooling tower, office, parking lot, warehouse and other necessary auxiliary buildings are within the boundaries of this area. The emergency planning zone is estimated to be about 8 hectares.<\/h3>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Cheaper<\/strong> - A small reactor nuclear power plant is called a. The small reactor reactor is smaller than a conventional nuclear plant and also requires less construction material, both in terms of total volume and electricity (MW) produced. Thus, the small reactor plant is more competitive than larger plants, as the smaller construction volume results in fewer construction delays (BWRX-300 can be built in 24-36 months). The simplicity of design and the proven performance of previous generations of BWRs also makes the BWRX-300 more cost-effective than other small reactors 60%.\u00a0<\/h3>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Safer<\/strong> - passive safety systems reduce the risk of accidents, caused by the loss of cooling water. Reactor steam condensation and cooling systems based on nature laws, ensure the safety of the reactor without human intervention, even in the most severe case of an unlikely accident, for at least a week. After which it is sufficient to add cooling water using a conventional water pump or fire truck pump. It is also sufficient to use one of the four water reservoirs to cool the reactor.<\/h3>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Established efficient supply chain<\/strong>
The reactor and its main components (steam separator, steam dryer, control rods and their actuators) as well as the isolated condensation system are used in many reactors. Experienced manufacturers exist in the USA, Canada, Japan, Mexico and Europe (GE Power's turbine factories in France and generator factories in Poland). The supply chain does not have to be built from scratch.<\/p>

Conventional components<\/strong>
The steam turbine and generator are off-the-shelf technologies produced by GE on a large scale. For example the TOPAIR generator has been manufactured, shipped and synchronized by GE in 3,570 units worldwide. Fermi Energia, in cooperation with Estonian mechanical engineering and manufacturing companies (Estanc, Estonian Heavy Indistries, Scanweld, BLRT, Maru, Aquaphor, Kunda Nordic Cement, etc.), is convinced that almost 30% of the components can be produced and delivered from Estonia.<\/p>

Familiar to regulators<\/strong>
Both in the USA and in Europe (Switzerland, Spain, Finland, Sweden, Germany) there are several energy companies with long-term safe and economical experience dealing with boiling water reactors. There is a group of BWR owners and a Japanese BWR Operator Training Center. Technology is familiar to national regulators and many technical support organizations. GE Hitachi has performed maintenance and replacement for dozens of reactors. The long-term operation of reactors (aging management) for 40-50 years is well known.<\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
