RiskSpectrum® provides confidence for Brazil’s nuclear plans.

Eletrobrás Termonuclear S/A becomes the first RiskSpectrum® software licensee in Brazil


Development of nuclear power generation in Brazil is now safer by design thanks to Lloyd's Register Energy's RiskSpectrum® software which is being used in the upcoming build by Eletrobrás Termonuclear of the all-new Angra 3 reactor with AREVA.

Edmundo Selvatici, Training and Safety Manager at Eletrobrás Termonuclear S/A says: "We chose Lloyd's Register Energy and their RiskSpectrum® software to help us safely develop our new nuclear power plant. RiskSpectrum® provides a complete set of tools for developing, documenting, quality assuring, and monitoring the risk in the operation of our plants."

Probabilistic safety analyses (PSA) – a feature of the RiskSpectrum® software – is being performed to demonstrate the safety of the new power plant in Brazil. The scope of PSA for Angra 3, Brazil's newest nuclear power plant under construction, is being performed through a contract with the plant designer, AREVA, which also utilizes RiskSpectrum® as its PSA development tool.

Eletrobrás Termonuclear S/A builds and operates nuclear plants in Brazil. The company generates around 3% of Brazil's electricity and meets more than 50% of Río de Janeiro state's power needs. It currently has two nuclear plants including the 640 MWe Angra I facility and the 1.350 MWe Angra II plant. Four more large reactors are proposed to come on line from 2020.

"Our work with Eletrobrás Termonuclear S/A shows the strength of their commitment to provide industry and the local community with the reassurance that they are addressing long-term nuclear capacity by using technically advanced risk and asset management tools that support the safe, effective development of nuclear power plant," says Ola Bäckström, Vice President of Software Development from the consulting arm of Lloyd's Register Energy.

The PSA model that is built in to the RiskSpectrum® software covers safety functions in a nuclear power plant. It is designed to analyse scenarios where safety systems are challenged by a set of initiating events, such as disturbances in the normal operation of the nuclear power plant. The results are required in the regulatory process that ensures continued safe operation of the nuclear plant.

Socio-political and economic conditions have given rise to the worldwide renaissance in nuclear power. The reality is that the global challenges of climate change and energy poverty still require solutions. Many countries are deploying or considering nuclear power for the first time because it is the only mature technology capable of generating base-load electricity that is clean, secure, affordable and dependable.

Jerzy Grynblat, Nuclear Business Director from the consulting arm of Lloyd's Register Energy, says: "Nuclear power has a pivotal role to play in tackling the global challenges of climate change, energy security and energy poverty, but the success of efforts by government and operators alike to build public confidence and trust will determine its influence.

"Nuclear must always have a high safety focus. The safety culture for nuclear must be built in by operating companies at every stage in the nuclear supply chain, and RiskSpectrum® is a critical part of that focus."

The RiskSpectrum® software is licensed for use at 50% of the world's nuclear power plants for PSA studies. 80% of nuclear power plants in Europe use RiskSpectrum® software.
