Julie Ezold

Julie Ezold is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Julie Ezold rather than just read about it. In short: Julie Ezold (née Graudons) is a nuclear engineer at the Oak Ridge National Laboratory. She is campaign manager for the 252-Californium Campaign and was involved with the discovery of tennessine.

Key takeaways

Julie Ezold belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Julie Ezold to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Julie Ezold from memory before moving on to harder problems.

Reference excerpt

Julie Ezold (née Graudons) is a nuclear engineer at the Oak Ridge National Laboratory. She is campaign manager for the 252-Californium Campaign and was involved with the discovery of tennessine.

Early life and education Ezold took lessons and performed in ballet, tap, jazz, and baton at Merritt's Dance Center in Schenectady, New York. In her fifth year she received an award for her examinations at Merritt. Her sixth grade teacher encouraged Ezold to pursue radio and nuclear chemistry due to her early interests in the field. During high school Ezold completed a summer program in nuclear chemistry at the University of Lynchburg. She studied nuclear engineering at Rensselaer Polytechnic Institute, graduating in 1990. She earned her master's degree in nuclear engineering in 1992 at North Carolina State University, Raleigh, NC using the High Flux Isotope Reactor at Oak Ridge National Laboratory.

Career Ezold has worked at Oak Ridge National Laboratory since completing her postgraduate studies in 1992. Her early work considered Iodine-129 using Neutron Activation Analysis. She is the Californium Program manager, responsible for producing 252-Californium, 249-Berkelium and 252-Einsteinium. One microgram of Californium-252 can emit 2 million neutrons a second. Her work concentrates on transuranium elements and applications. She received the US Department of Energy Defense Programs Award of Excellence in 2002. Her commitments to education were recognized at the UT-Battelle Awards Night for Exceptional Community Outreach. In 2009 she earned a Presidential Citation from the American Nuclear Society. She was awarded the Patricia Bryant Leadership Award of Nuclear Energy Institute's Women in Nuclear group. In 2010 Ezold was one of the team who discovered Tennessine. She studied the reactions of Berkelium-249 and Calcium-48, directly involved in the experiments and production of Berkelium-249 at Oak Ridge National Laboratory. Her recent work looks to optimize the production of transcurium isotopes. Also, for nuclear isotopes like nickel-63, selenium-75, and neptunium-237, Ezold designs and directs safe and efficient nuclear material processing research and development.

Awards and honors In 2018 she was recognized by Marquis Who's Who Top Engineers for her sustained contributions to nuclear engineering. In 2009 Ezold her leadership was recognized by the Nuclear Endergy Institute with the "Patricia Bryant Leadership Award for Women in Nuclear".

Worked examples

Example 1 — a first encounter with Julie Ezold

Start with the simplest possible case. Write down what Julie Ezold claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Julie Ezold before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Julie Ezold ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Julie Ezold

In research: Julie Ezold appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Julie Ezold in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Julie Ezold is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century American engineers, 20th-century American physicists, 20th-century American women physicists, so understanding it makes those chapters shorter.
In everyday life: Look for Julie Ezold outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
