Entergy CONDITION REPORT CR-IP2-2005-03557 Originator: Schwartz,Geoffrey E Originator Phone: 6684 Originator Group: Eng Project Mgmt Operability Required: Y Reportability Required: N Supervisor Name: Verrochi,Steven F Discovered Date: 09/01/2005 10:00 Initiated Date: 09/07/2005 16:06 Condition
Description:
This CR initiated by CA&A to copy a manual CR, which is attached to the suggested action section below with the original paper operability review.
A hairline crack several feet in length was found at approximately 60 foot level of Unit 2 spent fuel pool south wall on the loading bay side. The crack has evidence of liquid seepage with trace amounts of cesium 134. This was found during excavation associated with the dry cask storage project.
The crack was inspected by a structural engineer and the supervisor of Structural-Civil Engineering and does not pose an operability concern for the spent fuel pool.
It is a typical concrete crack that develops during forming, and is non-propagating. It was not created by the excavation, since excavation only removed loose soil and rocks whichwas not load-bearing for the wall. The pool is an independent structure not supported by adjacent material.
The activity is indicative of either a pinhole leak in the pool stainless steel interior liner, or is from seepage into the crack (which is now leaching out) during watering of the soil above the level of the crack to inhibit dust as it was being removed.
Immediate Action
Description:
Informed Shift Manager, Operations Manager, PLant Manager, Engineering Director. Performed inspections described above. Radiologically controlled the area. Also informed the NRC resident.
Suggested Action
Description:
(FROM 9/1/05 paper CR attached) Keep radiological controls in place, continue to monitor. Assign CR to Manager of Dry Cask Storage, who.will develop and implement a repair plan such as seal injection. Test liquid samples for boron (there is no evidence visible).

Description:
Inspect inside of Unit 3 SFP liner leak detection piping to determine if it is obstructed. If obstructions are found, CA closure requires initiation of Work Order which cannot be cancelled without Director of Engineering approval, to ensure obstructions are removed.
Response
See sub response below.
Subresponse:
The Unit 3 SFP liner was inspected by inserting a 19' long video prove into the pipe. No obstructions were found during this inspection. In addition, since the drain pipe is longer then 19' (it appears to be approximateluy 37' to 38' long) and a clear image could not be obtained much beyond the end of the probe, a metal snake was also inserted into the drain pipe. This snake was insetted approximately 37.5' and no obstructions were encountered. Minor amounst of water were also found in the
- pipe which would further confirm the absence of blocking of the'piping. Based on this information, it is concluded that no obstructions were found during this inspection.

Entergy CORRECTIVE ACTION CR-IP2-2005-03557 Subresponse:
In. order to facilitate the handling of Spent Fuel Casks, the area south of the Spent Fuel Pool, consisting of a concrete slab supported onto a rock foundation medium, had to be excavated in order to implement a reinforced concrete design that will provide proper anchorage and support for the crane handling the casks. During the excavation activities in the Fuel Storage Building Truck Loading Bay, located south of the Spent Fuel Pool, the rock drilling required the use of rather large amounts of water. Whenever drilling was in close proximity to the south wall of the Spent FuelPool, moist areas of the pool wall exposed after the rock removal normally dried out rather quickly. As rock was removed below Elevation 65', a mostly horizontal hairline crack was exposed. Over a length of approximately 9'-2", the westernmost portion of this hairline crack remained. moist. As the excavation continued, another mostly horizontal hairline crack at approximately Elevation 59'-I 1"did not dry out upon being exposed and a section approximately 3'-4" in length remained damp. As a result, on September 1 2005 Condition Report CR-IP2-2005-03557 was written. In the beginning of the problem description, the Condition Report stated that "A hairline crack several feet in length was found at approximately 60 foot level of Unit 2 spent fuel pool south wall on the loading bay side. The crackhas evidence of liquid seepage with trace amounts of cesium 134. This was found during excavation associated with the dry cask storage project." As there was no actual leakage from the damp cracks, a small tent with a collection point was installedover the damp areas. Amounts of condensed fluid for one day were in the 500 ml range.
In late September, a larger tent, covering both the upper and lower moist cracks was installed, and the daily condensation amount increased to approximately 1500 ml.
The area from where the leakage is being collected shall be covered by compacted sand backfill to support installation of a crane that will allow handling of the dry casks. The temporary collection system. needs to be replaced with a permanent collection system. As such, an ER is needed to develop a modification that will replace the temporary tenting over the moist concrete cracks area with a Stainless Steel container, and provide a drain and vent line that will facilitate the collection of condensate from the area where crack dampness was observed.
The permanent liquid collection system should consist of a collection box attached to the Spent Fuel Pool wall over the area where dampness was observed, a drain line routed to the PAB/Fan House Pipe Pen area to facilitate the liquid collection, and a vent line to facilitate drainage of the sealed box. The ER should indicate that, in terms of basic functions, critical characteristics and performance requirements, the liquid collection assembly must (1) cover the entire area where damp cracks were observed to exist, (2) support a boroscope inspection of the box and damp area of the Spent Fuel Pool wall, (3) provide for storage of a 30-day collection volume, with the daily volume collected being in the 1300 milliliters range. The liquid collection assembly must also (4) minimize any potential impacts on Fire and Accident Analyses, (5) provide for a safe installation, and (6) facilitate sampling by Chemistry.
Engineering Request ER No. IP2-05-26558 was developed and issued in response to this Corrective Action (DA Nuta 1.1 16 2005)

Description:
Perform a remote video inspection of the accessible sections of the spent fuel pool liner to identify the potential sources of the existing leakage. Any susceptible locations should be further investigated with a vacuum box or other similar method,
Response
A remote visual inspection of the accessible areas of the spent fuel pool liner has been performed to try to locate the potential source of the minor leakage detected through the defect on the south wall. This inspection covered the cask loading area and the portions of the pool walls/liner above approximately 2 feet above the top of the fuel assemblies (i.e. areas where cameras could withstand the radiation dose). These inspections (WO IP2-05-25553) identified three locations with brown staining which could be the source of the existing leakage. Following this remote visual examination, a diver entered the pool and performed a vacuum box test of the upper two indications. No detectable leakage was found during this inspection. The third location is scheduled to be vacuum box tested on November 17, 2005. The final inspection results will be documented in WO 1P2-05-26214.

Description:
- During CARB review of the Lower-Tier Apparent Cause Report, the CARB Chairman requested that a new CA be written to assess what action(s) can be put in place with triggers to detect future potential leakage. This CA is intended to address that request. CA response should describe actions implemented (monitoring wells and sampling protocol).
Response
Currently, IPEC is conducting weekly samples from all four monitoring wells located in the unit 2 transformer yard to track and trend suspected ground water leakage from the FSB or PAB--that data is suffient to detect any significant increase in ground water contamination from the unit 2 SFP--The data is reviewed by the special IPEC team weekly and discussed
- internally with RP and Chemistry--Additional wells are currently being installed to further characterize the HTO plume and quantify its concentration, flow rate and direction--Also a long term well monitoring plan is being developed per CR-IP2-2005-3986 and as such tracked to that CR No further actions necessary here as the reference CR will capture long term corrective actions for the HTO monitoring plan and remediation if necessary Subresponse:

Description:
Perform KT Analysis. Incorporate trend data from samples being taken.
Response
KT continues to be updated. U I SFP and the U2 RWST are not likely to be the source of the groundwater tritium based on the concentration gradient observed in the plume.
Work continues to characterize possible sources. Well installation and inspections of possible sources such as sumps continues. The "performance" of the KT will continue as requested until well installation is complete, and the strategy to characterize the plume is complete. An action is being entered to status the KT at the completion of well installation.
