No, the spill was discovered 13 years ago, but it happened even earlier. The article doesn't say when the spill from the 58-year-old building happened, just that it was detected 13 years ago. To me, the fact that an untold number of year passed before this massive, highly radioactive spill was detected, and the further fact that it took them 13 years to figure out how bad the spill was, doesn't inspire confidence that they have a full handle on the situation and have accurately measured just how widespread the contamination is.
The article did indicate that there was work being done in the 80’s during which the floor of a “hot cell” was damaged and allowed the radioactive material to leak out into the soil.
