My story: Abraham Weitzberg, ANS member since 1962
. . . and today.
Weitzberg then. . .
My first exposure to nuclear engineering was in 1956–57 when I was a fourth-year chemical engineering undergraduate at MIT. The previous summer, I worked at an oil refinery in New Jersey and our class visited a Monsanto sulfuric acid factory in Boston Harbor. I lost my enthusiasm for chemical engineering and decided to take a couple of introductory nuclear engineering courses as a senior. After a summer job at Y-12 in Oak Ridge, I started on a nuclear engineering master’s degree program. (An Atomic Energy Commission fellowship certainly helped my decision.)
The following summer, I performed reactor physics experiments at Brookhaven with Herb Kouts, Joe Hendrie, Rudy Sher, and Henry Windsor. In January 1962, after defending my Ph.D. dissertation on measuring uranium-238 capture in lattices of uranium rods in heavy water, I headed to Los Angeles to work on SNAP reactors for Atomics International. There, I performed critical experiments and managed their aerospace safety program.
Since 1911, PowerLabs has continually provided customers quality calibrations and testing. First established under the Philadelphia Electric Company’s testing section, we have since grown and expanded our laboratory capabilities not only in metrology but in testing and analysis over the last half century. Today, PowerLabs is the primary calibration and testing laboratory for Constellation. We have labs strategically located from the upper-Midwest to the Northeast to better support the urgent demands of quality driven industries.
We maintain both A2LA Accreditations for ISO 17025 calibrations and Appendix B calibrations, assuring our technical competence as a laboratory. Many of the listed parameters and ranges here are accredited. Please see our Scope of Accreditation for each of our sites on our website. As an Approved Nuclear Supplier, we adhere to strict code requirements including 10 CFR 50, Appendix B, NQA-1 and ANSI N45.2. These guidelines are the basis for which we have built our Quality Program.
