Light Water Reactors (LWR)

The light-water reactor (LWR) is a type of reactor that uses normal water, as opposed to heavy water, as both its coolant and neutron moderator; furthermore, a solid form of fissile elements is used as fuel. The LWR reactors are the most common type of nuclear reactor.

There are two versions of light-water reactors: the pressurized water reactor (PWR), and the boiling water reactor (BWR).

Micro-Modular Reactors (MMR)

NNE will also focus on a reactor size called Micro-Modular Reactors (MMR) or as we like to call them Nuclear Batteries. NNE uses the term nuclear batteries, as many of the different types can be in operation for a long-time on one charge.

The Nuclear Batteries have a number of advantages, some of which are as follows:

Scalability and flexibility
• Series production in a factory means very high costs.
• Can be installed very close to consumers.
• Can be increased in power depending on need.
• Low production costs result in low electricity prices.

Easy installation and commissioning
• From planning permission to commercial operation is approx. 12-15 months.
• Can be operated up to 20 years on one charge.
• Passive safety systems and innovative fuel.
• Modules are serially produced in the factory and consist of standard components.

Uncomplicated settlement
• No risk of spreading radioactive material.
• No need to store nuclear fuel on site.
• Spent fuel remains in the hearth (FCM).
• The spent fuel can be stored dry in, for example, a storage room without additional cooling in a decommissioned mine.

Rapid Advancement of Competence and Experience (RACE).

The purpose of RACE is to transfer competence and empirical knowledge from experienced nuclear power engineers to the energy engineers of the future. Through this competence transfer, it is also facilitated and ensured that Sweden's planable fossil-free electricity production maintains the highest imaginable level. We did it before and we can do it again.

Another aim is to accelerate learning so that skills can be put to use faster than in a traditional academic way. RACE is open to anyone in the energy industry, but is perhaps best suited to the nuclear industry.
