Effects of Radiation on Materials in a Nuclear Reactor
Amy GingVan Vleck High School / Van Vleck ISD
Dr. Lin ShaoDepartment of Nuclear Engineering
Nuclear Reactor
Effects of Radiation on Steel in the Reactor Vessel
Steel under radiation Irradiation Assisted Stress Corrosion Cracking (IASCC) Radiation + Stress + Environment
From the Lab to the Classroom
In the lab, we are measuring the resistance and resistivity of materials before they are exposed to radiation and after they are exposed to radiation
Resistivity is a measure of how many defects radiation has caused in the material that it has come in contact with
In the classroom, we will perform the same experiments and calculate the resistance and resistivity of provided samples
The Plan…Day One
Introduction / Overview What is radiation? How does it affect us in our daily lives? Radiation Applications – medical,
electricity Tie in with IPC class discussion on the
periodic table and radioactive elements
Day Two
What is the South Texas Project? What do they do out there? How much? Who uses it? Why do we care? What are the concerns?
Diagram of Plant Pictures of Damage
Homework will be a research project over nuclear power in the United States.

Day Three
Introduction to Resistance and Resistivity
Resistance V=I R Resistivity ρ=2πsR Homework over both equations, with
information provided, solving for one variable
Day Four
Hands – On Day (in IPC lab) Looking at periodic table, which sample should
react the least to radiation? Is this material a good choice for use in a reactor?
Use Four Point Probe to measure resistance of provided samples
Work at least one example together as a class Homework over both equations again, this time
over results found in the lab
Day Five
Review of Resistance and Resistivity Activity
What did the results mean? Which sample would react least to radiation?
Conclusion of Information Career opportunities at STP Education necessary for those careers Salary information for careers Possible speaker from STP on this day
Algebra I TEKS and TAKS Covered
a(2) – Algebraic thinking and symbolic reasoning
a(3) – Function concepts a(4) – Relationship between equations and
functions b(1)B – Gather and record data b(1)D – Represent relationships b(1)E – Interpret and make decisions b(3)A – Use symbols to represent unknowns
Sample Pre-Test Questions
Use the following equation to solve problems 4-5, A=l * w
4. Solve the equation for l.
a. l=A*w c. l=A/w
b. l * w= A d. l=w/A
5. Solve the equations for w.
a. w=A/l c. w=l * A
b. l= A/w d. w= l/A
What did I learn this summer?
A very broad understanding of the engineering field
A very narrow understanding of nuclear engineering, particle acceleration and the effects of radiation on materials
And most importantly…
Research is a slow process, filled with ups and downs, starts and stops, successes and failures.
But there is no such thing as failure in research, because we learn from every failure.
