Words and meanings to learn
control rods
are rods that can be inserted into the reactor core to absorb neutrons and slow down or stop the fission chain reaction.
moderator
a material (like water or graphite) used in a nuclear reactor to slow down the fast-moving neutrons, making it easier for them to cause more fission in the fuel.
fission
when the nucleus of a large atom (like uranium) splits into two smaller nuclei, releasing energy.
chain reaction
is a process where each nuclear fission event releases neutrons that cause more fission events, creating a continuous cycle.
reactor core
is the part of a nuclear reactor where the fission happens. It contains the fuel rods (made of uranium), the moderator, and other materials that control the reaction.
Samantha is an accomplished science educator whose current work centres on curriculum design and professional development, supporting teachers to deliver high-quality science education through evidence-informed approaches. She is a former Head of Chemistry and Sixth Form Tutor with extensive Key Stage 4 and 5 experience, and has worked as an AQA examiner, giving her valuable insight into assessment standards and what students need to succeed.
Underpinning this is a strong foundation in applied science built across a range of industry roles. Samantha has held scientific roles at John Smith's Brewery, Yorkshire Water and WasteCare, where she led technical projects, drove operational efficiencies and ensured compliance with industry standards. Across these roles she has first-hand experience of how scientific knowledge translates into measurable outcomes in professional and commercial environments.
