INTRODUCTION ~
LTo further the' demonstration effort begun in SCOUT, the PROTOTYPE Program was established to irradiate a large number of' test fuel : rods for the purpose of providing statistical data. on fuel perfo'rmance of alternate high burnup fuel designs.
This process is being accomplished
.in discrete step-wise ' fashion (with SCOUT and PROTOTYPE). to potentially.
l lead-the design of future'rel.oads.
l alternate fuel designs
~
which offer high potential for extended burnop are the: primary-design concepts used in this program.
PROTOTYPE ~ consists of 4 assemblics, three of which are identical.
The assemblies will be irradiated in symmetric positions within the core
- f-PROTOTYPE Gul0ELINES
- In designing the PROTOTYPE demonstration, certain guidelines were followed which aid in a description of the demonstration:
s
, 1.
No exterior changes' were made in the fuel rods or assemblies, 6
i.e., all changes wera limited to fuel and inte,rnals of the fuel rod.
-. 2. -
Test rod locations are non-limiting.
