E-CodeUranium enrichment: SWU and feed — a TI-84 Plus CE program
ENRICH is a TI-BASIC program for the TI-84 Plus CE. Feed and tails mass for a product assay from a feed and tails assay, separative work in SWU, and the feed and SWU needed per kilogram of product.
What it asks for and what it shows
It asks for 4 values at its prompts. In the example below it shows FEED KG, TAIL KG, SWU, SWU/KG, FEED/KG.
Example run
One of its oracle test cases: “4.5% LEU”. The inputs are typed in order, and the results are the values the case expects on the screen.
| Step | Value |
|---|---|
| You enter | |
| Input 1 | 4.5 |
| Input 2 | 0.25 |
| Input 3 | 0.711 |
| Input 4 | 1000 |
| The screen shows | |
FEED KG= | 9219.088937 |
TAIL KG= | 8219.088937 |
SWU= | 6871.112989 |
SWU/KG= | 6.871112989 |
FEED/KG= | 9.219088937 |
How it's checked
5 test cases, each checked against the textbook formula it uses. Replayed key by key on a virtual TI-84 Plus CE, they make 31 checks.
How E-Code checks every program
Run it or put it on your calculator
- Open the library in the TI-84 Plus CE calculator and pick “Uranium enrichment: SWU and feed” (ENRICH).
- Put it on your own calculator with a computer and a USB cable, or type it in by hand.
