EP-DR 1000 Emergency Plan Current Wording Proposed Wording Reason for Change Section EP-DR-1000 Note: This table provides a summary of changes to documents comprising the Dresden Emergency Plan: EP-DR-1000.

Besides the changes associated with the permanent shutdown evaluated below, there are multiple editorial changes that are proposed in this license amendment request, i.e. , they do not change the intent of the document. They do not impact the ability to comply with Regulatory Guidance or level of commitments made in the Emergency Plan. These changes are marked with revision bars within the Emergency Plan (except changes to step numbers); however, they are not specifically evaluated in the change assessment, since they are editorial. These include:

  • Changes in step numbers as a result of information which has been relocated or deleted .
  • Page number changes within the Table of Contents
  • Changes in the Table of Contents which reflect changes made within the Plan
  • Changes in Revision numbering and Revision History EP-DR-1000 IEMA Technical has both the command authority IEMATeel:lAieal has both the command authority for The revision replaces the reference to the IEMA Technical Part II Section A.2 .a for radiological aspects of a nuclear incident and the radiological aspects of a nuclear incident and the branch .

EP-AA-1004 Annex Besides the changes associated with the permanent shutdown evaluated below, there are multiple editorial changes that are proposed in this license amendment request, i.e., they do not change the intent of the document. They do not impact the ability to comply with Regulatory Guidance or level of commitments made in the Emergency Plan . These changes are marked with revision bars within the Emergency Plan (except changes to step numbers);

however, they are not specifically evaluated in the change assessment, since they are editorial. These include:

  • Changes in step numbers as a result of information which has been relocated or deleted .
