Information Requested 1
General, Front Sections Please explain the extent to which NEI 99-01, Rev. 5, will be incorporated or explain why not. Please note any other sections in the updated NEI guidance that may add value to the EALs for your site:
3.9 Emergency Action Levels 3.10 Treatment of Multiple Events and Classification Level Upgrading 3.11 Emergency Classification Level Downgrading 3.12 Classifying Transient Events 3.13 Operating Mode Applicability 2
Section 3.2 Please explain the basis for choosing to adopt new Operating Mode definitions for implementation of NEI 99-01 EALs. Specifically, explain why having Operating Modes 1 (power), 2 (hot standby), 3 (hot shutdown), 4 (cold shutdown), 5 (refuel), and D (defueled) would not work for your EALs. Normally, EAL Operating Modes are reserved for Operating Modes as stated in the approved Technical Specifications (TS), with the addition of D (defueled).
3 Section 3.3 Please explain the extent to which NEI 99-01 Rev. 5, definitions will be adopted and identify any variances that OPPD proposes to take from those definitions. Explain the basis for any differences.
Normally, definitions in a scheme change are adopted uniformly with the exception of definitions specific to plant type (i.e., PWR or BWR).
