Jacobs (NYSE:J) was selected to lead an international consortium whose cutting-edge research could lead to extensions in the operational lifespan of nuclear power plants around the world.
The INCEFA-SCALE program (Increasing safety in nuclear power plants by covering gaps in Environmental Fatigue Assessment) aims to reduce uncertainties about how critical components will perform when subjected to the harsh conditions inside operational nuclear power reactors.
Although components and materials are extensively tested in laboratories, there are sometimes gaps in understanding the correlation between these tests and actual performance. This can lead to fatigue assessment parameters being set more conservatively than necessary.
The research will fill in those gaps by means of extensive data mining in international fatigue databases and detailed examination of test specimens to improve mechanistic understanding. Greater certainty about component performance will avoid unnecessary closures of nuclear power plants when they are still economically viable and safe to operate.
"By successfully leading this research, Jacobs has demonstrated its capability to knit together an international consortium and to bring together the very best, complementary capabilities," said Jacobs Critical Mission Solutions International Senior Vice President Clive White. "The European Union has sanctioned this follow-on project while the predecessor project is still live, which testifies to the success of the consortium and the relevance of the study topic to nuclear plant safety and lifetime assessments."
Operator of the U.K.'s largest independent nuclear laboratory complex in Birchwood Park, Warrington, Jacobs will contribute to multiaxial, thermo-mechanical and complex waveform testing to provide greater insight into the stresses and strains placed on components. This work will complement component scale tests being carried out in the U.S. by the Electric Power Research Institute, in collaboration with INCEFA-SCALE.
The European Union is providing most of the funding for the five-year, $8.1 million INCEFA-SCALE program, which is a continuation of the previous INCEFA-PLUS program, where Jacobs have led a 16-member European consortium since 2013.
With $13 billion in revenue and a talent force of more than 55,000, Jacobs provides a full spectrum of professional services including consulting, technical, scientific and project delivery for the government and private sector.
