36 years after the Chornobyl crisis, Ukraine presents a test for nuclear reactor survivability

This story was originally published in The Revelator.

CHORNOBYL, UKRAINE — It took less than a minute after an unexpected power surge for one of the nuclear reactors at Chornobyl (Chernobyl in the Russian spelling) to explode on April 26, 1986, ripping the roof off and spewing dangerous toxins into the air.

The event, and emergency cleanup that followed, left 30 workers dead, thousands exposed to cancer-causing nuclear material and later death, and a legacy of radiation. Now, 36 years later and with war raging, Ukraine is desperate to prevent another nuclear disaster.

Nuclear reactors generate more than half of the country’s power. Ukraine is the first country with such a large and established nuclear energy program to experience war, according to the International Atomic Energy Agency.

Richard Lagdon is Professor of Practice in Nuclear Engineering at the University of Tennessee. He also is Engineering Manager, Systems Integration and Chief Engineer, Nuclear Operations & Safety with Bechtel National Inc. Reston, VA.
He will review the status of current projects for Natrium and VTR fast reactors, the challenges of advanced reactor licensing and how the development of the Nuclear Licensing Course NE486/586 at UT reckons with these challenges. 

He has forty years of progressive nuclear experience managing projects, developing technical policy, interfacing with stakeholders and developing long range plans. He is an accomplished nuclear professional, practiced in engineering, emergency operations, plant startups and conduct of operations while supporting operational goals.

From working as Shift Test Engineer for the reactors of the nuclear Navy to developing life cycle maintenance plans for aircraft carriers, Captain Lagdon’s broad range of assignments over 30 years in the Navy Reserves, earned him the Leo Bilger award for outstanding leadership. The civilian side of his career included a decade as Chief of Nuclear Safety in the U.S. Department of Energy, where he lead nuclear construction reviews for projects totaling more than $15 billion.

While some hope that nuclear energy will end the climate crisis others point out that it will be too expensive and take too long to scale up while climate disasters grow exponentially. What most can agree upon is that the reliable output of existing nuclear plants remains indispensable for the foreseeable future and that maintaining their safety is paramount.
