Helen Ltd has initiated a Nuclear energy program with the aim of incorporating nuclear energy into Helen's energy system producing carbon-free district heat and potentially electricity as well. The first phase of the multi-year program evaluates various nuclear plant technologies and suppliers as well as screens potential plant locations. The first phase of the program is scheduled to be completed in 2026. Based on the results of the first phase Helen will proceed with the program by detailing the design solutions with preferred plant supplier on a dedicated site(s).

To achieve the goals of the program, Helen is looking for experienced and solution oriented partners to support the project in making technical evaluations and specifications and proactively resolving any technical issues in a cooperative and constructive manner. Helen expects from partners capability to lead the works of given assignments and draw holistic conclusions on wide cross disciplinary questions. Technical evaluations and specifications cover e.g.

The partner shall have in-depth knowledge of the Finnish nuclear legislation and ability to apply it.

The procurement is divided into Parts 1 and 2:

Part 1 – Nuclear & radiation safety and licensing :

• Evaluation of nuclear and radiation safety aspects in design

o compatibility of design solutions with the Finnish regulations and guidelines

o compatibility of design solutions with international regulations, guidelines and standards

• Review of safety related licensing and design documentation, e.g. PSAR and FSAR

• Execution of deterministic safety analyses

• Probabilistic safety assessments

Part 2 – Plant technology, production and construction:

• Evaluation of plant alternatives production capabilities and operational aspects

• Evaluation of the technical characteristics of the plant alternatives, (technical disciplines)

o compatibility of design solutions with international regulations and standards

o compatibility of design solutions with Finnish regulations and guidelines

o design processes and design management

• Evaluation of the facility's operability, usability and life cycle management (maintenance, waste, etc.)

• Evaluation of the facility's constructability and the cost-effectiveness of design solutions

• Evaluation and characterization of the plant site alternatives and plant-site compatibility

Tenderer can offer either Part 1 or Part 2 or both Parts.

During execution of the technical support services, the technical evaluations and specifications will be conducted following Helen Oy's instructions using Helen Oy's structure and criteria set for evaluation.

Partner shall have inhouse engineering capabilities to design facilities and conduct nuclear and radiation safety related analyzes.
