2009-01 Achieving New Nuclear Virtual Plant Configuration Management

ProgressStandard Configuration Management Reference Model• The Standard Configuration Management Reference Model draft is

undergoing a complete re-write. New Nuclear Plant XML Equipment Schemas• The Schema viewer is complete. The project is working with the

Hydraulic Institute, NIST and a pump vendor to conduct a pump procurement pilot to determine nuclear specific fields. Also planning pilots with valve operators and electric motors

• We are running into more issues with the standardization of XML schemas that anyone had anticipated. The original concern that a few “nuclear specific” fields may be missing has turned into an effort involving schema terminology, complexity, architecture refinement, document maturity validity, etc. Feedback to FIATECH

Information Handover Guide• The Handover Guide was published in December 2009 (1019221).• Developing Handover Life Cycle and data requirements.

2009-08 Safety Related Stationary Battery Qualification

Project Description• EPRI Utility Requirements Document (URD) states that Advanced Light Water

Reactors (ALWRs) shall utilize passive safety systems to mitigate design basis events up to 72 hours in duration– Passive systems must rely upon stored energy, e.g., batteries

• Passive plants (AP1000, ESBWR) require batteries that are qualified to a 72 hour duty cycle

• IEEE 535 standard for battery qualification (endorsed by RG 1.158) did not cover duty cycles beyond 8 hours

• IEEE 535 only covers Vented Lead Acid (VLA or flooded) batteries – Valve Regulated Lead Acid (VRLA) batteries are not addressed

Value• Providing a industry solution to a first-of-a-kind technical challenge for passive

plants• Reducing risk through a collaborative approach

2010-02 Digital RT

Summary of Issue• Currently, the industry is unable to address the evaluation and qualification of

filmless radiography systems to detect planar and volumetric fabrication flaws with selected digital detector panels (DR), phosphor plates (CR), and high energy electronic radiation sources capable of penetrating the material thicknesses typically encountered in plant applications

Potential Benefit of Project• Expedited ASME Section III volumetric examination of piping welds with CR

or DR• Volumetric option/complement to UT• Minimization of weld repairs with ASME Section III volumetric examination• Digital storage of images instead of processed film and associated chemical

processing

2010-05 NDE Digital Data

Summary of Issue

• Archival data is required by the Nuclear Regulatory Commission (NRC) to last for the plant's working lifetime

• Many utilities' document control departments will not accept digital non-destructive examination (NDE) data for archival storage and require it to be converted to a hard copy format

Potential Benefit of Project

• This guide will assist utilities in transferring, retrieving, and archiving their NDE data and allow them a path for any future digital NDE data needs

• A consistent and acceptable process is needed for archiving digital NDE records, versus converting them to paper records

2010-10 Concrete Embedded Sensors

Summary of Issue

• Large concrete structures in nuclear power plants are typically not feasible to replace. These structures can show signs of concrete degradation by the time they go for license renewal

• There is a distinct need for frequent inspections of these types of concrete structures. One of the largest hindrances to concrete inspection is the lack of accessibility to many concrete structures

Potential Benefit of Project

• Optimize inspections

• Better positioned for long-term asset management

2010-11 Technical Basis for HDPE Above-Ground Use

Summary of Issue• There is no ASME approved code case for above-ground HDPE pipe. One

has been developed for below-ground use only • Several new plant designs plan on using HDPE for above-ground applicationPotential Benefit of Project• Use of HDPE for above-ground applications will require development of

appropriate design and construction rules, along with determining the engineering and material properties needed to ensure safe and reliable design and operation 

• Critical technical issues that will be addressed include: – seismic qualification (including vents and drains) – large displacements and interactions during thermal expansion and

transients– fire– structural damping values– damage during operations

Project A – Double-walled HDPE Piping Evaluation

Issue• 10 CFR 20.1406, “Minimization of Contamination,” requires licensees to

minimize contamination and radioactive waste generation • RG 1.143 states that plastic pipe should not be used.• Doubled walled HDPE is a desired optionDescription• Review the double walled HDPE piping options available to meet the current

regulations, including hardware and leak detection / monitoring options. • This work would include further understanding the HDPE materials

degradation properties and limitation for exposure to radioactive fluids. • Work to inform a revision to RG 1.143 to acknowledge the option of using

double walled plastic pipe (HDPE), with built-in leak detection capability, • Value

• HDPE is viewed as a superior material to steel in some applications and is preferred for buried systems

• Providing an alternative in the RG will provide greater flexibility

• Cost savings on materials, installation and long term operations

32© 2010 Electric Power Research Institute, Inc. All rights reserved.

Project B – EPRI Groundwater Protection Guidelines for New Nuclear Power Plants

Issue• The EPRI Groundwater Protection Guidelines for Nuclear Power Plants

(1015118) provides technical guidance for implementing a groundwater protection program that meets the requirements of NEI 07-07. However, it currently does not provide technical guidance for implementing groundwater protection programs, namely the evaluation of plant design and operational procedures, for new plants as outlined in NEI 08-08.

Description• EPRI will develop an extension to the EPRI Groundwater Protection

Guidelines that provides technical guidance for implementing a groundwater protection program per 10CFR20.1406, RG 4.21, and NEI 08-08.

Value

• Understanding and preparing for any potential leaks or spills during construction will allow nuclear power plant operator to quickly identify and address any leaks or spills during operation.

• Timely leak detection and response will increase stakeholder confidence that utilities are protecting public and environmental health and safety.

Project F – NDE Techniques for Concrete Void Detection and Sizing

Issue• The main types of degradation related to concrete are the existence of honeycombs

and voids due to lack of adequate concrete placement and vibration. • These types of problems are related to poor design and construction, which are the

leading causes of age-related degradation in concrete structures

Description• Voids (the focus will be on detection capabilities during the placement so that issues

can be corrected immediately before curing.)• Wall separation due to concrete shrinkage• Damage under loadings (internal cracks, excessive stress and strain, etc...)

Value• Voids in concrete severely reduce the structural and shielding capacity of the concrete

structure. The ability for early void detection in a nuclear construction environment will result in both financial and safety improvements.

• Long term asset management will also benefit from early detection and correction of construction issues with concrete structures.

Project G - URD Update Project

Issue• No formal process exists to maintain the URD• No comprehensive listing of EPRI reports applicable to new plants exists Description• Review and disposition the “Margins and Monitoring” work to ensure those

recommendations are incorporated into the appropriate URD sections.• Establish EPRI report reference sections for each chapter of the URD• Establish a process for a) collecting input from URD users for review under

a specific schedule and b) review newly issued EPRI reports and industry references for inclusion into the URD where appropriate.

Value• The results of the Margins work will be visible and reflected in the URD.• Relevant EPRI nuclear sector reports on designing, procuring and

constructing new nuclear plants will be comprehensively identified in the URD

• URD users will benefit from a process to ensure that their input for changes to the URD are managed in a systematic and timely manner.

Project I - QA for 2D and 3D Design and Modeling Software and V&V for Quality Software

Issue

• The 2D and 3D design and modeling software currently being used to design and ultimately construct the next generation of nuclear power plants do not have to meet NQA-1 requirements for software and data quality. Hence, in order for these systems to be used for the operation of the nuclear power plant – a qualification of the software and data will have to occur.

Description

• Configuration Control of the Data in Engineering Applications that will have Plant Life Cycle use

• Quality Control of the 2D / 3D design and modeling software and other associated databases and software in a commercial grade dedication method prescribed by NQA-1

Value

• An industry standard approach to software and data quality for the 2D and 3D design and modeling software and other associated databases and software.

Project R – High Strength Rebar use in Nuclear Power Plants

Issue• The use of higher strength rebar in the design and construction of safety

related concrete structures and / or containment structures could result in cost savings for new nuclear power plants by reducing the quantity of rebar required. Cost savings would result from reduced rebar material purchase costs and reduced construction cost due to reduction in the quantity of rebar placed

Description• Develop and implement a concrete testing program to support adoption of

higher strength rebar use in ACI 349 and ACI 359. • Involve the NRC to facilitate endorsement of the higher strength rebar in a

future revision of Reg. Guide 1.142.Value• The use of High Strength Rebar in the general construction industry has

made high strength concrete in seismic zones cheaper and easier to construct due to the lower density of rebar in structures.

• High Strength Rebar has greater resistance to corrosion over convention rebar, providing a potential longer life in nuclear plant application.
