Penfield and Enos: Outage planning in the COVID-19 era
Energy Harbor’s Beaver Valley plant, located about 34 miles northwest of Pittsburgh, Pa., was one of many nuclear sites preparing for a scheduled outage as the coronavirus pandemic intensified in March. The baseline objective of any planned outage—to complete refueling on time and get back to producing power—was complicated by the need to prevent the transmission of COVID-19.
While over 200 of the plant’s 850 staff members worked from home to support the outage, about 800 contractors were brought in for jobs that could only be done on-site. Nuclear News Staff Writer Susan Gallier talked with Beaver Valley Site Vice President Rod Penfield and General Plant Manager Matt Enos about the planning and communication required.
Beaver Valley can look forward to several more outages in the future, now that plans to shut down the two Westinghouse pressurized water reactors, each rated at about 960 MWe, were reversed in March. “The deactivation announcement happened in the middle of all our planning,” Enos said. “It’s a shame we haven’t had a chance to get together as a large group and celebrate that yet.”
While the focus remains on safe pandemic operations, the site now has two causes for celebration: an outage success and a long future ahead.

This paper reports the main results of the activation analysis of the ARIES-ACT1 power plant and its attractive environmental characteristics. The approach aims at examining several activation-related effects that influence the neutron-induced radioactivity, decay heat, waste classification, recyclability, and clearability of radioactive materials. Detailed studies are presented and provide information about the interdependence of material choices and activation response functions. It is also shown how the activation analysis can help address the inboard decay heat problem, one of the most important safety-related issues for tokamaks, and point the way to proper solutions through redefining the radial build to meet the design needs. Furthermore, the study suggests an integral management strategy to change what is now a costly waste disposal concern for fusion into a valued commodity via the further development of the recycling and clearance approaches.
