{{#Wiki_filter:ENT000618 Submitted: August 10, 2015 Randy G. Lott Consulting Engineer Westinghouse Electric Company, LLC Primary Systems Design and Repair Randy Lott (BSE, nuclear engineering, University of Michigan; M.S., Ph.D., nuclear engineering, University of Wisconsin) is a Consulting Engineer at Westinghouse Electric Company with over 35 years of experience in nuclear materials and radiation effects. Since joining Westinghouse in 1979, Dr. Lott has been a lead test engineer in the Remote Metallographic (Hot Cell) Facility. In this capacity, he has been responsible for numerous investigations of materials-related issues in PWRs. He has supervised testing of RPV surveillance capsules and conducted research programs on irradiation embrittlement and annealing of RPV steels. In addition, he has pioneered the application of the Master Curve testing to characterize the ductile-to-brittle fracture toughness transition in RPV steels. His contributions have provided the basis for the reconsideration of Nuclear Regulatory Guide 1.99, Radiation Embrittlement of Reactor Vessel Materials, Revision 2 (May 1988), the development of Westinghouse RPV annealing technology, the safety analysis of reactor tanks at Savannah River, the determination of crack growth rates used in alternative plugging criteria for nuclear steam generators and the evaluation of RVI performance.
During his career at Westinghouse Dr. Lott has participated in the evaluation of aging degradation or failure of numerous reactor components including steam generator tubing, BMI flux thimbles, control rod guide tube split pins, baffle-former bolts and clevis insert bolts. He has also conducted numerous research programs on highly irradiated stainless steels, including tensile, fracture toughness and IASCC testing.
For the past eight years, he has been actively involved in the design and implementation of AMPs for RVIs.
As a member of the MRP Reactor Internals Inspection and Evaluation Core Group, Dr. Lott contributed to the EPRI Materials Reliability Program Pressurized Water Reactor Internal Inspection and Evaluation Guidelines (MRP-227-A). His work on aging management strategies for the Westinghouse and Combustion Engineering plants provided the basis for the recommended guidelines. The same recommendations have been adopted in the most recent revision of the NRCs Generic Aging Lessons Leaned (GALL) Report (NUREG-1801).
