The space below each of the following questions may be used to record the results of judgments and findings.Additional space is provided at the end of this checklist for documenting other comments.1. Does anchorage of equipment in the area appear to be free of potentially adverse seismic conditions (if visible without necessarily opening cabinets)?

Yes 2. Does anchorage of equipment in the area appear to be free of significant degraded conditions?

Yes 3. Based on a visual inspection from the floor, do the cable/conduit raceways and HVAC ducting appear to be free of potentially adverse seismic conditions (e.g., condition of supports is adequate and fill conditions of cable trays appear to be inside acceptable limits)?Yes 4. Does it appear that the area is free of potentially adverse seismic spatial interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

Yes 5. Does it appear that the area is free of potentially adverse seismic interactions that could cause flooding or spray in the area?Yes 6.

Seven and six of these items were located in containment for DCCNP1 and DCCNP2 inside the Shield Wall and could not be included in the walkdown when the units were at power. There were eight and nine electrical equipment items that could not be opened during the walkdown due to safety reasons.The remaining items (one in each unit) were in enclosures that also could not be opened for safety reasons in the Auxiliary Building.

The electrical equipment items will be inspected at the next service outage for this equipment.

The items in containment and the two items in enclosures in Auxiliary Building will be inspected during the next RFO for the respective unit.Table E-1 and E2 summarizes the reasons each item is inaccessible during normal plant operation.

There are also three Area Walk-Bys associated with the items in Containment.

It is noted that all accessible areas of the plant included Area Walk-bys including the rooms containing inaccessible electrical equipment.

Cook Unit I and Unit 2 Instructions for Completing Checklist This peer review checklist may be used to document the review of the Seismic Walkdown Equipment List (SWEL) in accordance with Section 6: Peer Review. The space below each question in this checklist should be used to describe any findings identified during the peer review process and how the SWEL may have changed to address those findings.

Additional space is provided at the end of this checklist for documenting other comments.1. Were the five safety functions adequately represented in the SWELl selection?

YN NEI The basis for how selection of equipment for the SWEL I is described in the SWEL Scope Development document and the basis includes a description that indicates that the 5 safety functions are represented.

However, the information provided on the SWEL does not include the safety function(s) supported by each item.2. Does SWEL 1 include an appropriate representation of items having the following sample selection attributes:

a. Various types of systems?b. Major new and replacement equipment?

The basis for how selection of equipment for the SWEL I is described in the SWEL Scope Development document and the basis includes a description that indicates that modified and new equipment is considered.

However, the information provided on the SWEL does not indicate if the equipment is new or has been modified.c. Various types of equipment?

d. Various environments?

It appears that the equipment on the SWEL is located in various environments.

Although not specifically required by the EPRI TR 1025286, it appears that equipment in the Drywell is not represented.
