A. PURPOSE PROGRAM SECTION No. SEP-UIP-IPEC Revision No. 0 Page 5 of 69 The purpose of this Program Section is to document the site's inspection plan for underground piping and tanks. The inspection plan development represents a specific commitment milestone in the NEI Industry Initiative that is due by June 30, 2011. B. BACKGROUND Many nuclear plant systems contain one or more lines that are underground or buried. These systems may include safety and non-safety service water, circulating water, fire protection, diesel fuel oil, spent-fuel pool cooling water, miscellaneous radioactive lines, off-gas and yard drains. Many buried lines are coated or tape-wrapped with materials such as concrete, coal tar, asphalt-based materials, or epoxy. Although many of these lines were cathodically protected when plants were constructed, in many cases the cathodic protection system may not have been maintained or used consistently. The result is accelerated external degradation at locations where the coating has failed. Additionally, certain systems can be subject to internal corrosion as a result of microbiologically iniluenced corrosion (MIC) and other degradation mechanisms. Over the past several years there have been instances of inadvertent releases of licensed material due to underground and buried piping leaks from nuclear power plants. While none of these instances have threatened public health and nuclear safety or compromised environmental protection, public confidence in the safe operation of nuclear power plants has been affected and needs to be addressed. ...--"""'" 0 """'" ('I) N 0 0 () w 0... .,....

DEFINITIONS PROGRAM SECTION No. SEP*UIP*IPEC Revision No. 0 Page 7 of 69 Buried Piping and Tanks -Piping and tanks that are below grade and in direct contact with the soil or concrete (e.g. a wall penetration or embedded in concrete). Cathodic Protection {CP} Tile application of a current to the outside swiace of the pipe with the purpose of reducing tile susceptibility of exposed sections of buried pipe (exposure caused by coating deterioration, damage, or voids) to corrosion. The application of a low voltage residual current causes a shift (with respect to the anode) of tile electrolytic potential at pipe exposed sites and thereby places the pipe in a more protected, less corrosive environment. Direct Examination --Examination performed so as to be capable of mapping and categorizing corrosion defects. Direct exam may include soil excavations that enable visual testing (VT), and manual measurements [including: ultrasonic testing (UT), radiological testing (RT), pit gage] to be performed. Direct examination can also include "smart pigging". Indirect inspection -Inspection that provides information on the condition of an underground pipe remotely; from ground level or from an exposed section of pipe that is distant or remote from the pipe section of interest. Reasonable Assurance (RA) -Reasonable Assurance is obtained when an engineering evaluation {including Fitness--for-Service), indirect inspections, direct examinations, and remediation, if necessary, of underground components is performed. Such a combination of activities will provide a high level of confidence that the structural and leak integrity of the piping systems will be maintained. Underground Piping and Tanks -Piping and tanks that are below grade and that may or may not be in direct contact with soil or concrete'. This includes piping and tanks that are directly buried and those that are embedded in concrete or located in underground concrete vauits, tunnels, or guard pipes.

E. CORROSION OF METAL PIPE PROGRAM SECTION No. SEP-UIP*IPEC Revision No. 0 Page 8 of 69 As coatings become damaged as a result of holiday formation, coal tar enamel embrittlement, tape wrap disbanding, etc., buried piping is directly exposed to soil. Without effective cathodic protection there is increased potential for external corrosion of the metal pipe. Corrosion mechanisms of metals in buried pipe can be categorized in three broad categories:

1. Wall thinning:

This category encompasses electrochemical effects that typically result in general wall loss or local wall loss such as pitting, general corrosion, galvanic corrosion, crevice corrosion, microbiologically influenced corrosion, erosion-corrosion, and preferential weld attack (grooving).

2. Environmental cracking:

This category encompasses inter-granular or granular cracks such as stress corrosion cracking, hydrogen induced cracking, and fatigue cracking.

3. Metallurgical effects: This category encompasses all degradation effects that cause a change to the metal microstructure or its mechanical propertiE:s.

F. CURRENT INDUSTRY EFFORTS The industry, under the Nuclear Energy Institute's (NEI) leadership, established in the summer of 20091he Buried Piping lndustly Task Force {BPITF) that is composed of NEI, Electric Power Research Institute {EPR!), Institute of Nuclear Power Operations (IN PO), American Nuclear Insurers (ANI), and representatives. The BPITF developed the Nuclear Strategic Issues Advisory Committee (NSIAC) Buried Piping Integrity Initiative (approved by the industry's chief nuclear officers in November 2009, Reference 2} and the associated NEI 09-14, "Guideline for the Management of Buried Piping Integrity" (January 2010, Reference 3). The scope of the initiative includes all piping that is below grade, contains any fluid, and is in direct contact with the soil. The initiative was later submitted to the NRC via a letter from NEI (Reference and tanks and below or are direct contact with the are safety related or contain licensed materia! or are known to be contaminated with licensed materiaL The Buried Piping Integrity Initiative and Tanks !ntearitv Initiative"* this """" """" 0 """" (Y') N 0 0 () w 0...

PROGRAM SECTION No. SEP-UIP-IPEC Revision No. 0 Page 9 of 69 The initiative includes commitments for developing an inspection or condition assessment plan by June 30, 2011 for the initial buried piping scope and by December 31, 2012 for the added underground components scope of the initiative. The pian is to provide reasonable assurance of integrity of the associated components and shall include the following key attributes: identification of underground (below grade and buried ) piping and tanks to be assessed. Potential inspection/assessment techniques . inspection/assessment schedule for underground components based on risk ranking and prioritization, $ Assessment of cathodic protection, if applicable. G. CURRENT ENTERGY EFFORTS Scope was identified and risk ranking criteria were developed to help the Entergy Fleet prioritize the inspections of underground pipes and components subject to degradation initiating from either the inside of the pipe (ID initiated), or the outside of the pipe (OD initiated), or both acting in combination. Impact assessment (based on safety, public risk and economics} and corrosion risk assessment (based on soil resistivity, drainage, material and cathodic protection/coating) were initially completed to determine an inspection priority (high, medium, low). The prioritization is determined by the use of a risk matrix that rates the likelihood of failure against the consequences of failure for a given system, structure, or component (SSC) location. Since radiological SSCs were by definition considered high risk, these were futiher risk ranked relative to one another and characterized as high-high, high-medium, or high-low risk. The required inspections are selected depending upon the risk ranking. Those components and structures ranked the highest will be addressed with a higher priority and will be examined more extensively. The components and structures ranked in the medium and lowest category may be candidates for initial deferral. commodities is obtained whEm Fitness-for-Service evaluation, Indirect B:<aminations, and remediation, if necessary, is performed. Such a combination of activities will provide a high level of confidence that the structural and/or will be maintained. 1.[) """" 0 """" ('I) N 0 0 () w 0.... 1.0 "<t 0 "<t ("") N 0 0 () UJ [l_ PROGRAM SECTION NO. SEP-UIP-IPEC No. 0 Page 10 of 69 The RA guidelines establish methods for grouping of similarly designed and constructed piping lines and then prioritizing them for inspection. The RA guidelines provide minimum requirements for indirect inspection and direct examination of piping as well as post assessment techniques to establish Reasonable Assurance of Integrity. The Entergy-Exelon guidelines for RA are currently being reviewed by an EPRI Technical Advisory Group (TAG), of which Entergy is a member, for use across tile industry and for inclusion in the upcoming revision to NEI 09-14. H. INSPECTION STRATEGY AND METHODOLOG.IES Detailed descriptions and discussions have been provided for the various available inspection/examination techniques and tools for buried piping and tanks. These can be found in EPRI Report IR-2010-409 (Reference 12). Specific recommended Inspection/examination methodologies for buried pipes and tanks are summarized herein. Preferred Inspection Mejl:Jodologies for Piping Option 1: Use of Internal Direct Examination Pig In-line pipeline examination provides the most accurate means of mapping the wall's ttlickness condition. As a result the use of in-line examination plays an important role in developing reasonable assurance of integrity. These instrumented vehicles (called pigs) require access and possibly exit points in the piping system to enable deployment. Additionally, the deployment of the vehicle is best suited to certain piping configurations that should be assessed and determined prior to use of this method (Reference 12), Option 2: Use of Guided Wave Indirect Inspection The guided wave approach provides rapid assessment of wall loss over relatively long runs of pipe. The guided wave inspection may be performed without taking the process pipe out-of-service. The guided wave inspection is limited to approximately 50 feet of pipe in either direction, and is limited to detecting pits and remaining wall thickness. Readings beyond a flange cannot be performed has to (0 """" 0 """" ('I) N 0 0 () w 0.... <D '<t 0 '<t ("") N 0 0 () UJ a.. PROGRAM SECTION No. SEP-UIP-!PEC Revision No. 0 Page 11 of 69 The locations for pe1iorming inspection will be based on the results of a soil survey to determine the most adverse locations, together with above grade survey to detect potential coating damage, to determine inspection locations. At inspection locations, local NDE of the pipe shall be performed together with guided wave inspection. Option 3: Use of Local Pipe Direct Examination NDE Pipe direct examination NDE utilizes direct measurement at exposed sections of the pipe. The locations for pe1iorming examinations will be based on the results of a soil survey to determine the most adverse locations, together with above grade survey, to detect potential coating damage to determine examination locations. Pipe Line Grouping Grouping of pipes for inspection is recommended in order to reduce the overall inspection cost and duration. Pipes can be grouped based on attributes such as pipe material, coating type, soil/backfill, age, operating parameters, size, process fluid, cathodic protection, and others. The specific grouping parameters will depend on the specific features of ihe components. The grouping of pipes with similar attributes may allow the results of the inspection to be extrapolated from one pipe to the others in the group, therefore reducing the number of excavations and cost. Completed direct examinations and results may be able to be applied to the entire underground line and to other pipes in the grouping. The Fitness Service Engineering Evaluation will be able to use this information to calculate remaining life and the time until the next scheduled inspection. Guidelines relative to grouping for inspection are outlined within Attachment B of Reference 9, "Fleet Guidance for the Determination of Reasonable Assurance for Structural and/or Leakage Integrity for High Risk Underground Piping". 8 groups were identified for the site: """ 0 """" ('I) N 0 0 () w 0...

Pipe Une inspection Locations PROGRAM SECTION No. SEP-UIP-IPEC Revision No. 0 Page 12 of 69 Excavations should be performed to maximize the potential to obtain information for the subject pipe and for other pipes that can be exposed in the same excavation. Several pipes being excavated in one location is preferred, but not required. Excavations shall be large enough such that a direct examination shall assess a minimum 10 feet length of pipe, if feasible. Inspection locations should be selected considering the risk ranking criteria and other information such as: Results of risk ranking. Inspections st1ould be distributed among the higher ranked locations. Locations where piping goes through penetrations into vaults or other structures. This includes pipe that is both encased and not encased in concrete. Locations where the pipe enters or exits the soiL Locations of dissimilar materials in contact without use of insulating kits. e Locations where the pipe enters or exits water.

• Results of ID visual examinations.

Results of CP surveys and coating surveys. Select locations where CP and coating surveys cannot be performed or are questionable. Results of any remote inspections that have been performed. Plant or industry operating experience.

• Trending of past inspection results. Opportunistic inspections during maintenance activities (e.g., open valves).
• Cost and access can be considered when the risk rankings are similar. The inspection and examination to be performed on an underground pipe or tank should be defined based on the expectation of susceptibility and the risk ranking results. The decision and basis for the decision on for inspections and examinations should be documented.

Specific guidelines for inspection of buried piping are outlined within Attachment B of Reference 9, "Fleet Guidance for the Determination of Assurance for Structural and/or Leakage Integrity for High Risk Underground Piping".

Strategy for Building and Storm Drains Relative to reasonable assurance of integrity of exterior building and storm drains, the inspection strategy should be performed as a plant facilities' action to inspect for clogging, debris, and basic functionality. Establishing basic functionality of storm drains is important since the design of such systems, often utilizing bell and spigot concrete or cast ductile iron pipe, can be susceptible to leakage as a result of joint separation from settlement or soil erosion undermining the support of the pipe. The site will establish a PM frequency for this SSC. As an example, an initial inspection frequency can be established and adjusted based on the results of inspection for continuity. If the pipe has been in place for a number of years and has not be subjected to ground surface disturbances, then a longer inspection period beyond the initial inspection could be warranted and justified. Drainage piping subject to local vicinity excavation from site const1uction activities, haul path loading, or soil erosion (as examples), may warrant a shortE:r inspection period to ensure continuity of flow, PM frequency to ensure flow path (removing any clogging from site debris} may be warranted on a shorter cycle to that for establishing continuity, based on specific site conditions. Mitigation and leak management strategies should be implemented if !he drains are found to be leaking or degraded.

Strategy for Cathodic Protection PROGRAM SECTION No. SEP-UIP-IPEC Revision No. 0 Page 14 of 69 An effective cathodic protection system is essential to minimize underground piping corrosion. However, most Entergy plant's cathodic protection systems were initially installed during plant construction and were rarely maintained. and in some cases abandoned thereafter rendering the systems incapable of providing the needed corrosion protection. In addition, many site modifications rendering underground piping network even more complex were implemented since initial plant construction without evaluating the required potential updates to the system. Therefore, it is recommended to conduct an Area Potential and Earth Current (APEC) Survey to analyze and implement needed improvements to the corrosion control (coatings) and cathodic protection effectiveness of the station. Once the system modifications are implemented, the system will be maintained via recurring PMs based on vendor recommendations. L OPERATING EXPERIENCE (OE) The Underground Piping and Tanks Engineering Team examined operating experience via condition repo1i LO-HONL0-2008-15. This CR examined Entergy, nuclear industry, and petro-chemical industry events relating to underground and buried piping. Each site subsequently proposed inspection locations to verify underground/buried equipment fidelity (e.g. LO-HQNL0-2008-15 CA 387 through 395). For this inspection plan, the OE lessons-learned examined are summarized below in the form of inspection goals (e.g., items to consider when making detailed inspection procedures) and inspection criteria. In general, LO-HONL0-2008-i 5 revealed that most underground and buried piping failures dealt primarily with legacy issues (e.g., equipment not being originally installed, operated, or maintained properly) and not pipeline aging per se. By using this insight, sma!ier inspection goals and criteria have been developed for use in inspection procedures. 0 1.[) 0 """" ('I) N 0 0 () w 0... 0 1.0 0 '<t ('"") N 0 0 () UJ a...

This includes proper voltages, run time, and periodic maintenance.

3. Be alert for potential mechanical sneak circuits (e.g. piping failures caused bv more than one stressor, or a not-so-obvious stressor) that may exist in the inspection path. These include: Previous leakage events that change underground soil conditions and create failures in adjacent equipment.

Basis OE revealed that building penetration challenged pipe integrity. OE has revealed that many cathodic protection systems are improperly installed or improperly operated. Making this determination prior to excavation can prepare the inspection team for needed corrective action and operab;lity contingencies. Approximately 35% of events in HQNL0-2008-00015 were caused by multiple stressors that defeated place barriers. These events can be characterized as: 1. Proximitv failures (one event causing damage to adjacent equipment. This could be one leak that causes another leak or stray current).

2. (evaporation and subseauent condensation outside the barrier, moat/drain cleanliness issues leadina to defeated barrier, internal vers<JS external corrosion as the main driver).
