Division Spotlight
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

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.
Ionizing radiation affects living things on the atomic level by ionizing cells. When the radiation reaches a cell, any of the following can happen.
In addition, there is evidence to suggest that unless radiation exposure reaches ten (10) times the normal background level, there is no harm to humans from radiation. Furthermore, there appears to be evidence that radiation at or near the normal background level may be beneficial to, and even necessary, for life.
For low levels of radiation exposure (under 10,000 mrem), the biological effects are so small they may not be detected at all. The body’s natural repair mechanisms often repair any damage to the cells before any effect is felt or detected. This protective effect of low levels of radiation is called “radiation hormesis.”
