Basic Statistical Analysis of LWR Pin Power Data
This article details the basic mathematical formulas used to statistically compare pin power data sets from a reference and an alternate LWR.
Due to the migration of our articles from MediaWiki to Markdown, the formulas are not showing up properly. Unfortunately, Markdown does not have a lot of support for mathematical characters. We will soon be migrating back to MediaWiki pages, at which point this article will be back to normal.

Pin Power Dataset Representation
First, let's view the pin power dataset of each LWR as a 4D matrix P(i, j, k, l) where
Variable | Represents |
---|---|
i | pin row |
j | pin column |
k | axial level |
l | assembly number |
In order to compare two of these pin power datasets, we shall define the following 4D pin power datasets:
Variable | Represents |
---|---|
A | reference power data set |
B | alternate power data set |
C | power difference data set |
where
_C = B - A _ (a basic power difference)
or
_C = (B - A) / A _ (a relative power difference)
In addition, each element in C can be weighted by a 4D matrix W.
