Nuclear Power Generation Company · Nuclear Safety Case
Framework explorer, with document tiers and scope
Each cell is a department × element intersection. Documents are stacked by tier, so the document pyramid appears in every cell. Use the scope selector to see what applies company-wide, at station level or in a single reactor unit. Click a cell to see its documents.
The same 202 documents, seen through Nuclear Safety Case. This is a subset lens: it asks one question of every document and keeps those that answer yes. 27 do; the other 175 are outside it by design and still belong to the management system. Nothing is copied between frameworks: each document is recorded once and carries its position in every framework.
“If this document changed, would the change have to be categorised as affecting the safety case, independently assessed, and possibly agreed with the regulator before it is made?”

175 documents are not safety case baseline
They answered no to the question above. That is not a gap: a subset lens is only useful if it leaves most of the system out. They remain in the management system and in every integrated framework view.
