Location (Bldg, Elev, Room/Area): Area : AUX, 70, CAL-AB-512 Instructions for Completing Checklist This checklist may be used to document the results of the Area Walk-By near one or more SWEL items. The space below each of the following questions may be used to record the results of judgments and findings.

1. Does anchorage of equipment in the area appear to be free of potentially Yes adverse seismic conditions (if visible without necessarily opening cabinets)?

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

Tubing support has dislodged from its wall and some tubing is no longer clipped into its supports, however the tubing is very light and flexible and judged to be adequately supported, therefore not a seismic concern.

3. Based on a visual inspection from the floor, do the cable/conduit raceways and Yes 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)?

Cable tray and conduit supports are attachedto building steel and judged acceptable.

Ducts in area are hung off braced frames and rods; no seismic concern noted.

4. Does it appear that the area is free of potentially adverse seismic spatial Yes interactions with other equipment in the area (e.g., ceiling tiles and lighting)?

Masonry block walls, identified as A, B, C, ZZ and A 1 on drawing A-260, are safety-related and thus seismically ratedper IE Bulletin 80-11.

An overhead light near AHU #11 is supported by clamping to an overhead duct. The clamp surface is slightly sloped such that clamps may fall (i.e. slip off) and light will potentially strike duct, and remain suspended from conduit, either way the light will not adversely affect the AHU. Judged not to be a seismic concern, but SWEs recommend correcting this condition.

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

6. Does it appear that the area is free of potentially adverse seismic interactions Yes that could cause a fire in the area?

Observed an unrestrainedstep ladderbut it is far from equipment and judged not a seismic concern.

A Tall ladder is restrainedbelow its center of gravity, but equipment is protected by steel in the path of ladder movement and thus is not a seismic concern.

A smoke detectorattachment was found on a GaitronicsBox, however it is not a seismic concern.

8. Have you looked for and found no other seismic conditions that could Yes adversely affect the safety functions of the equipment in the area?

Plan for Future Seismic Walkdown of Inaccessible Equipment As shown in the SWEL for Calvert Cliffs Unit I in Attachment 2, several items have been deferred until the next refueling outage (RFO). Table E-1 summarizes the reasons each item is inaccessible during normal plant operation, and notes the planned Seismic Walkdown date. There are also Area Walk-Bys associated with these items.

All items will be walked down during the next RFO, scheduled for completion on March 11, 2014. An updated submittal report will be provided on June 15, 2014.

Inaccessibility code:

a. Inspection requires entry into Primary Containment. (Walkdown performed at full power.)

b. Inspection requires access to environmental enclosure.

c. Inspection requires access to locked high radiation area.

d. Inspection requires access to air handling unit.

e. Inspection requires entry into confined space. (Inspection of non-anchorage items performed.)

Table E-2 includes the list of equipment items that require supplemental internal inspections because they were not opened during the walkdowns. Cabinets that have been identified as requiring these supplemental internal inspections are those with doors or panels with latches or thumbscrews and can be readily opened during normal maintenance activities. Also provided for each cabinet is a proposed schedule for performing these internal inspections.

1) Additional internal anchorage also needs verification during this supplementary walkdown.

In addition there are eleven (11) equipment items that were not opened during the walkdowns and do not have maintenance scheduled. To remove these from service an entire safety related bus must be de-energized, which puts the plant at significant risk. It is unsafe to open these while they are in service.

SWEL 2 Development Screen 4 - SFP Rapid Drain Down The process to identify SSCs that could cause rapid drain-down of the SFP is identified in Screen #4 of the Seismic Walkdown Guidance [Reference I]. Per the Guidance, rapid drain-down is defined as lowering the water level to the top of the fuel assemblies within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> after an earthquake.

Determination of the potential for rapid drain-down includes the following assessment:

Determine whether there are SFP penetrations below about 10 ft above the top of the fuel assemblies.

The top of the fuel assemblies are at elevation 44'-2.5". Therefore the SFP will be checked for penetrations below elevation 54'-2.5". A review of the SFP liner drawings [References 16 - 18] indicates pipe embedments exist for SFP Cooling at elevation 65'-1 I". Also, penetrations for the SFP skimmers are located at elevation 63'-8" [References 24 - 26]. These penetrations are located above the elevation range of concern and will not be considered.

The only penetrations in the range of concern are the fuel transfer tubes at elevation 35'-6" [References 16 & 19]. The transfer tubes are isolated on the SFP side with 36-inch gate valves. The valves are seismically installed and are designed not to fail during a seismic event. The isolation valves are locked shut in Modes I - 4 per Reference 27. The transfer tubes are sealed on the Refueling Pool side with blind flanges. The blind flanges are leak tested per Reference 28. Based on the transfer tube assembly's seismic capacity and the fact that it is inaccessible for a walkdown, the transfer tubes will be eliminated from the scope of SWEL 2. The transfer tubes have component names 1PEN42 and 2PEN42, which are considered part of the Containment Structure (System 059).

Deep suction lines exist in the SFP that were originally designed to drain the pool for maintenance or decommissioning. The two lines are part of the normal SFP Cooling System; however, the deep lines are isolated with valves that are locked shut. Goose neck siphon breaks are installed on the deep lines that are designed to prevent inadvertent draining of the pool. The use of this line-up is procedurally controlled by Reference 28. The lines are open ended at elevation 34'-6" however they penetrate the pool at elevation 65'-11", which is out of the range of concern.

SFP Cooling return lines also exist that have a similar configuration to the deep suction lines. These 2 lines are open ended at elevation 30'-6" and penetrate the pool at elevation 65'- 11 ", which is out of the range of concern. Siphon breaks exist on these lines to prevent inadvertent draining of the pool.

The SFP is designed to preclude the loss of structural integrity. If a leak from the SFP were to occur, the capabilities for controlling the leak are as follows:

Makeup water can be supplied indefinitely to the SFP at a rate of at least 150 gpm. It can usually be supplied at a greater rate for a period of many days, but this depends upon plant conditions.

Abnormal Operating Procedures (AOP) and Severe Accident Management Guidelines address loss of and restoration of SFP level.

A 3/16-inch stainless steel liner is installed on the inside of the SFP for leak tightness. All of the liner plate welds have leak-test channels welded to the outer side. The channels are grouped into 10 zones, each with its own detector pipe to localize leaks in the liner seams [Reference 30].

ATTACHMENT 5 INACCESSIBLE EQUIPMENT AND PEER REVIEW The Tech Spec LCO [Reference 23] states the SFP water level shall be > 21.5 ft over the top of the irradiated fuel assemblies seated in the storage racks, and > 19.8 ft over the top of fuel assemblies seated on rack spacers in the storage racks for reconstitution activities. This LCO is applicable during movement of irradiated fuel assemblies in the SFP.
