STUK approves periodic safety assessment of Fortum’s Loviisa power plant

STUK (Finland’s Radiation and Nuclear Safety Authority) notes in its decision

on the Loviisa nuclear power plant’s periodic safety assessment, published on 6

February 2017, that continued operation of the Loviisa nuclear power plant is

safe and meets the requirements set by legislation.



In 2007, the Loviisa power plant’s operating licenses were extended to 2027

(for unit one) and 2030 (for unit two) on the condition that a periodic safety

assessment of the plants be performed every ten years. STUK requires that two

periodic safety assessments of the Loviisa power plant are performed during the

license period.



Fortum submitted the first periodic safety assessment materials for STUK’s

approval within the required timetable, i.e. by the end of 2015. In practice,

the assessment is a massive set of reports and documents regarding the nuclear

power plant’s safety status, the possible targets of development, and the

maintaining of the safety. The scope of the periodic safety assessment

corresponds to the assessment performed in conjunction with the renewal of an

operating license. In addition to the documents submitted by the company, STUK

has performed various inspections at the power plant.



“The Loviisa power plant has produced electricity with nuclear power for nearly

forty years. During this time, safety and availability have been continuously

developed with new technical improvements and by continuously investing in

know-how and in the development of the safety culture,” says Deputy Director

Thomas Buddas, responsible for nuclear safety at the Loviisa power plant.



“The most extensive modernisation programme in the Loviisa power plant’s

history is currently under way and will ensure safe and reliable electricity

production to the end of the existing operating licenses. The safety

improvements included in the programme will be implemented at both plant units

in 2016-2018, and STUK is monitoring and overseeing the progress of the

projects as part of continuous monitoring,” Buddas continues.

Nuclear plants’ periodic safety assessments in Finland and at Loviisa power

plant

Renewal of a nuclear power plant’s operating license requires a thorough

assessment of safety. If the operating license is granted for a period longer

than 10 years, STUK will conduct a periodic safety assessment during the

operating license period. The scope of the safety assessment corresponds to the

assessment performed in conjunction with a renewal of the operating license.

The assessments review the condition of the plant, and especially the impact of

ageing on the plant and its equipment and structures. Additionally, the

conditions of the organisation for the continued safe operation of the plant

are assessed.



A condition of the operating licenses granted to the Loviisa power plant in

2007 is that two periodic safety assessments are carried out during the license

period. The first of them was submitted for STUK’s approval at the end of 2015,

and the second one will be submitted by the end of 2023.



Loviisa power plant

In 2016, the load factor at Fortum’s fully-owned Loviisa nuclear power plant

was 91.1%. On an international scale, the load factor was among the best in the

world for pressurised water reactor power plants. The plant produced a total of

8.33 terawatt hours, which is approximately 13% of Finland’s total electricity

production. The Loviisa power plant employs approximately 500 Fortum employees

and 100 permanent contractors. In 2016, Fortum invested EUR 100 million into

the Loviisa nuclear power plant.
