• This curve is valid for all assemblies that have cooled at least 9 years.

• • All assemblies loaded into DSC must meet the source spectra requirements of Technical Specification 2.1.

• • • This bounding radiological limit curve may be superceded with bundle specific source spectra calculations based on actual cooling times.
