1. Rationale
The major changes that are being proposed are summarized as follows: The term end-of-license (EOL) was replaced with the term maximum design fluence (MDF) to provide a consistent means to scale the capsule withdrawal schedule independent of different definitions and lengths of license life used by different regulatory authorities. Dosimeter measurements other than from the capsules are recommended, if there are long periods between capsule withdrawals. The amount of required archive material and the material sampling were changed in consideration of small modular reactor designs. An additional restriction on specimen location was added consistent with ASME NB-2223.
