Limiting Factors of Plant Life Time • Technical Life Time
• Components which are demanding, expensive or very time consuming to change, e.g. containment
• Difficulties to modify the NPP to fulfil the newest safety regulations
• Economical Life Time• Costs of plant modifications become bigger than replacement costs with
same technical properties (new power plant)
• Strategic Life Time• New political decisions• Remarkable changes of the energy business environment• Availability of the nuclear fuel
17
Pertti Simola15.10.2007
Development Principles of TVO NPP’s• Power plant units are improved continuously instead of one-time major investments• Technical development is exploited
• new safety requirements• advanced design solutions
• Own and other plants operational experiences and best practises are utilized• PSA-, cost-benefit -, and probabilistic availability analysis methods are applied• Well-functioning contacts to vendor and consulting companies as well as to research institutes and to regulatory body• The modifications are implemented during normal service outages⇒Goal: Rolling 40 years lifetime
