Mark Peres Mr. Mark Peres

Mark Peres is the Vice President of Engineering at Kairos Power. He is responsible for engineering design of the Kairos Power Fluoride-Salt-Cooled High-Temperature Reactor (KP-FHR). His focus is on developing a plant that is safe, will work, can be constructed, and that clients will buy.

With nearly four decades of experience in the nuclear industry, Mark previously served as Executive Project Director in Fluor’s Nuclear Power Group and Fluor’s Project Manager for a Small Module Reactor (SMR) project. Peres led Fluor’s support to the NuScale SMR from design development to the industry’s first design certification application for an SMR that was submitted to the Nuclear Regulatory Commission. He was also responsible for the reactor plant design, including the reactor module, structures, balance-of-plant, safety analyses, and fuel and core design. Mark also successfully managed several challenging projects including the $2.5 billion K Basins Closure Project, as Vice President, responsible for removing 2,100 metric tons of spent nuclear fuel and more than 50 cubic yards of radioactive sludge from two Cold War era fuel storage basins. Earlier in his career, Mark was a reactor operator and shift manager at the sodium cooled Fast Flux Test Facility (FFTF).

Peres received a Bachelor of Science degree in Mechanical Engineering from Montana State University, and a Master of Science degree in Mechanical Engineering from Washington State University. He has completed required coursework for a PhD in Nuclear Engineering from the University of South Carolina.
