LO-IP3L0-2008-00151-CA-19 due on 29-DEC-08 Document the actions taken and results determined in response to ISE Panel recommendation (R-7) to explore options for reducing the vulnerability of buried piping to the occurrence of any future unanticipated leak. Such options include excavating a few selected locations to confirm the presence of protective coating on the piping, as well as to measure and confirm the existence of sufficient wall thickness of the thus exposed piping using existing inspection techniques (Reference ISE Report page # 51)

RESPONSE

The response to the ISE Panel recommendation regards buried piping, IPEC has completed the following actions:

1. Excavation and visual inspection of underground CST condensate piping
2. Determination of wall thickness at locations exhibiting degraded pipe coating
3. Soil sampling
4. Development of long term inspection plans for IPEC buried pipe.

These items are addressed below.

1. Excavation and visual inspection of underground condensate piping IPEC performed excavations and inspections of the piping from the Unit 2 Condensate Storage Tank (CST) to the Auxiliary Feedwater Pump Building (AFPB) in October/November 2008. There are three underground pipe lines that run in parallel from the CST (El. 80 ft) to the AFPB (El. 15 ft):
  • 12 inch Line 1505, Aux Feedwater Pumps suction line from the CST
  • 8 inch Line 1509, CST condensate fill line
  • 10 inch overflow line, to manhole #5 Lines 1505 and 1509 are carbon steel, schedule 40. These lines were deemed not to require cathodic protection during original plant design due to favorable soil resistivity and drainage characteristics. As a defensive against localized corrosion attack, however, Lines 1505 and 1509 are externally coated with coal tar enamel and have a coal tar enamel saturated felt overwrap. The overflow line (corrugated carbon steel pipe) has a coal tar enamel internal and external coating. These pipes are sloped from the CST elevation to the AFPB, and are each approximately 320-330 feet in length. The design drawings indicate a minimum of 5 feet of ground cover over the pipe. Actual excavation at the lower location, however, required going down to a depth of approx.

20 feet to uncover the piping.

The Lines 1505 and 1509 are safety related.

These lines were selected for inspection from among the buried piping at IPEC that is ranked as high priority based on the assessmen~ of the piping's safety significance, potential radiological impact of a piping IPEC00161426

failure and impact on plant operations, and of the piping's corrosion risk. Specifically, the IP2 condensate system is a candidate to have tritiated water due to its interface with the feedwater system, and due to residual contamination associated with the steam generator tube rupture that occurred in 2000. Attachment 1 provides an overview of the assessment and ranking methodology.

These three underground piping lines were excavated at two locations.

The first location was in the horizontal run of pipe near the base of the CST, hereafter referred to as the upper location. The second was at the approximate one-third point along it's sloped length, hereafter referred to as the lower location. Refer to Attachment 2.

At the upper location there were five areas of degraded external pipe coating. (Ref. Condition Report IP2-CR-2008-04754) These areas had only minimal surface corrosion.

Based on visual inspection of the upper location, except for these areas of the degraded coating, the pipe and coating appeared to be sound, with no additional areas of coating discoloration, separation, blistering, peeling, bubbling, etc.

At the lower location, there was one localized pipe coating failure, and what appeared to be coating damage to the overflow line (scraping of the coating on the upper crests on the corrugated pipe) suffered during the excavation itself. The localized coating failure was a linear circumferential discontinuity in the coating approx. 4-5 inches in length at the top of the 8" diameter pipe, with a small amount of corrosion product emanating from it. Based on the generally good appearance of the piping and the small amount of corrosion product, the coatings engineer did not recommend removing the coating for a ultrasonic determination of the pipe wall thickness.

2. Determination of wall thickness at locations with degraded pipe coating At the locations of degraded pipe coating, the coating was removed to the bare metal to permit determination of the wall thickness using ultrasonic methods (UT).

The results of the UT's showed that the wall thicknesses were within the manufacturing tolerance of the nominal thickness. Based on these UT results, and of the visual inspections and results, it was determined that additional inspections were not required given the overall good condition of the inspected locations.

3. Soil sampling Samples were periodically taken as the excavation progressed. The soil analysis did not indicate any extraordinary activity (only naturally occurring isotopes).

Detailed soil analysis was also performed to characterize the corrosive parameters of ~he soil. These results will be captured, and e~aluated fer possible impact an corrosion risk assessments performed to date.

IPEC00161427

Limited soil resistivity measurements were taken by a Cathodic Protection contractor at the CST excavation areas, which resulted in average area readings slightly lower (more corrosive than had been assumed in the initial corrosion risk assessment for the inspected piping). However, as this piping is already part of the high impact and high inspection priority grouping, there is no impact on the schedule for future inspections of these lines, or on the associated re-inspection interval.

4. Development of long term inspection plans As part of the IPEC Buried Piping and Tank Inspection and Monitoring Program, preliminary long term inspection plan schedules have been developed. Attachments 3 & 4.

While these schedules are subject to revision due to supplemental data collection and supplemental above ground surveys, schedule and resource optimization against system w6rk windows, they capture the scope of the buried pipe inspection plan.

LO-IPJL0-2008-00151 CA#19, Attachment 1 IPEC BURIED PIPING IMPACT ASSESSMENT, CORROSION RISK RANKING AND INSPECTION PRIORITIZATION METHODOLOGY The IPEC Buried Piping and Tank Inspection and Monitoring Program is being developed iaw EN-DC-343. The following is a summary of the methodology to develop inspection priorities and inspection intervals.

Once all buried piping systems are identified, they are assessed as having High, Medium or Low Impact, based on the consequences of a failure of the piping in the following areas:

  • Safety (High= Nuclear Safety Related; Medium= Augmented Quality/Category M; Low= non-safety related)
  • Public risk (High = potential radiological consequence; Medium =

environment discharge or hazardous fluid; Low= non-contaminated, non-hazardous fluids)

  • Economic impact of equipment failure on plant operation (High= >$1M; Medium= $100K- $1M; Low= <$100K.)

Table 1 presents the details for performing the impact assessment.

Using the impact assessment results, the High Impact systems are Corrosion Risk assessed with consideration of the following four (4) factors:

1. soil resistivity
2. drainage
3. material
4. coatings/cathodic protection.

Tables 2 and 3 present the details for performing the corrosion risk assessments.

Corrosion risk assessments will be performed sequentially for the High, Medium and Low Impact systems.

In conjunction with the corrosion risk assessments, the inspection priorities for performing the initial inspections and subsequent inspection intervals are determined for each buried piping system in accordance with the Impact and Corrosion Risk assessments. Table 4 provides the guidance for scheduling these inspections.

Buried pipe inspection parameters will include:

  • External pipe coating and wrap condition
  • Pipe wall thickness degradation
  • Cathodic protection effectiveness (if applicable) 12/26/08 IPEC00161429 IPEC00161429

Table 1 -Impact Assessment High Medium Low Augmented QP Safety (class per Non-Safety Safety Related and Fire EN-DC-167) Related Protection Radioactive Chemical/Oil Untreated Water, Public Risk Contamination Treated System SW, Demin. Water e.g. Tritium gases Economics (Cost of buried > $1 M or potential

$100K- $1M < $100K equipment shutdown failure to plant)

Notes:

1. Any buried section with at least one High Impact gets an overall High Impact rating.
2. Any buried section with no High Impact rating but at least one Medium Impact rating gets an overall rating of Medium Impact.
3. Any buried section with all Low Impact ratings is to be rated as Low Impact.
