9TH GRADE NUCLEAR ENGINEERING
Scott Griffin
Bay City Independent School District
High School IPC teacher
E3 Summer 2008 Research topic:
“Flooding” during countercurrent flow
Mentor: Dr. Karen Vierow
TAMU Nuclear Engineering Dept.
THE PRINCIPLES AND CONCEPTS THAT RELATE TO MY
STUDENTSTAKS Objectives 4&5 – Chemistry and
Physics
Fission – Elements - Atomic particles - Phase
Heat transfer - Boiling Point - Work, Power and Energy - Nuclear power
TAKS Objective 1 – Lab Safety and The Scientific Method
Accurate measurements – Data Collection and Recording – Graphing Data
AT BAY CITY:
We start with Chemistry – so, the students will have been exposed to the terms and concepts that pertain to chemistry
I will use this project as a “special week” to tie together the Chemistry & Physics aspects
Also to promote the “Engineering” and Nuclear power opportunities that are opening up for them
Pre-testDiagnostic tool
Some of the questions will be from previously covered material
Some from material to be discussed during the week’s activities
Sample:
At what temperature does water boil
A. 100 F
B. 100 C
C. 200 F
D. 212 C
Some Questions from Released
TAKS tests
In winter the air just above the top bunk of a
bunk bed is warmer than the air just above
the bottom bunk because warm air rises.
Which of the following describes the method of
heating that causes this difference in
temperature?
F. Radiation from the room
G. Heat transfer through the walls
H. Convection currents in the room
J. Heat conduction through the bed
TWO LAB ACTIVITIES
1. Who can get their water the hottest?
Boiling is getting rid of heat – 100 degrees C max.
Pressure – Boiling point elevation – Phase change – Nuclear primary loop
2. Heat Transfer in Electrical Power Generation
“Primary Loop” – “Secondary Loop” Heating – Efficiency – Safety – Environmental impact
MESSIN’ WITH THEIR MINDS
Lab Activity
Who can get their water the hottest?
Obviously, VERY CAREFUL SUPERVISION IS REQUIRED ALONG WITH STRONG WARNINGS OF THE DANGERS INVOLVED WHEN DEALING WITH HEAT AND STEAM.
MATERIALS NEEDED: Hotplates, Ring stands, Bunsen burners, beakers or small saucepans, thermometers
Announce that there will be a lab activity in the form of a competition today.
Get the students into as many teams as your equipment and lab space will allow.
Allow them to choose either a hotplate or Bunsen burners for a heat source.
With EXTREME CAUTION, let them heat the water until boiling.
OF COURSE everyone will have the same temperature.
Turn off all heat sources and explain what “boiling” is.
NOW heat some water in a pressure cooker equipped with a pressure gauge and a thermometer.
Explain “boiling point elevation” and how pressure affects the phase change.
Show how this principle is directly related to the primary loop of a pressurized water reactor at a nuclear power plant. ( 550 degrees F and 2200PSI)
Heat Transfer lab
Heat Transfer Lab
Purpose: To understand how heat is transferred from a “primary” loop to a “secondary”
system without mixing the two water sources.
Goal: To record the rate at which the secondary system absorbs heat from the primary loop.
Materials: Hot plate, 2 Erlenmeyer flasks, 2 Thermometers, 3 feet of copper tubing, a
two-hole rubber stopper, timer.
Setup and procedure:
Fill both flasks about half full.
Place two-hole stopper in one of the flasks and place it on the hot plate.
(Place the other flask on a heat resistant surface next to the hot plate.)
Install the copper tubing through one of the holes in the stopper, (just into the air space, NOT into the water.) The coil end of the copper tubing goes into the other flask, (all the way into the water.
Place one thermometer through the other hole in the stopper, (all the way into the water. The second thermometer goes into the other flask.
Students need to understand how
“NUCLEAR” worksIt’s safe
It’s efficient
It’s clean
TAKS & TEKS
TAKS objectives 1, 4 & 51 - Scientific method – accurate measurements
4 & 5 – Chemistry and Physics
TEKS - (c) Knowledge and skills.
(1) Scientific processes. The
student, for at least 40% of instructional time, conducts field and laboratory investigations using safe, environmentally
appropriate, and ethical practices.
The student is expected to:
(A) demonstrate safe practices during field and laboratory investigations; and
(B) make wise choices in the use and conservation of resources and the disposal or recycling of materials.
(2) Scientific processes. The student uses scientific methods during field and laboratory investigations.
The student is expected to:
(A) plan and implement investigative procedures including asking questions, formulating testable hypotheses, and
selecting equipment and technology;
(B) collect data and make measurements with precision;
(C) organize, analyze, evaluate, make inferences, and predict trends from data; and
(D) communicate valid conclusions.
