for each site.

• How is the course structured?

• What is the current delivery schedule?


What is the intended student population?

• This is a general overview course is intended to introduce the basics of Quality Assurance

• Therefore, the intended student population is very broad. It includes:– Personnel not considered to be experts in Quality Assurance– Any individual who wishes to obtain a working knowledge of

Quality Assurance

• Almost every employee could find value

• This is intended to be a “Entry Level/Introduction” class


Overall Course Goals• Provide the student with a basic understanding of Quality

Assurance’s role in the licensing of nuclear power plants.

• The Course’s Major Goal is to enable the student to view Quality Assurance/Appendix B as:– A logical collection of necessary, pre-planned activities.

• The successful completion of these activities is critical.

• Introduce the students to selected topics and terminology related to specialized areas of Quality Assurance (QA).

• The actual course slides introducing the Course Learning Objectives follow.


Course Learning ObjectivesThe student shall :

1. Define and Describe the Relationship between:

• 10 CFR 50 Appendix B

• Quality Assurance Topical Report for CGS

• Quality Assurance Program Implementing Procedures

• Facility Operating License

• 10 CFR 50.54

2. Define and Identify the Elements of the Quality Assurance Program Associated with Routine Facility Operation

3. Define and Identify:

• The difference between a Performance-based and a Process-based Audit Plan

• Basic Components versus Commercial Grade Items

• The application of 10 CFR 21.21

• The application of a “Barrier” model for event preventionClick to Advance to

“How is the course structured?”

This is the Major Goal.


How is the course structured?

• The course is one day in length

• The course’s first phase overviews QA’s role in:– The initial licensing process and the Facility Operating License

• The class is introduced to each site’s Quality Program– Each site’s Topical Report/program and implementing procedure

is briefly reviewed.

• A comedy routine from vaudeville’s past is used to identify activities that represent practiced and pre-planned behavior.– A link is made to analogous pre-planned activities at NPPs

• This begins to demystify QA and supports the Major Goal previously described


How is the course structured?(Cont.)

• The second phase tells a “six segment story”– The class identifies the critical activities for each segment.– After the class identifies the required activity, the Appendix B

requirement is examined

• The “story” is a realistic sequence that details the identification and resolution of a defect in the Main Control Room Ventilation System.– This is the bulk of the course.

• Selected specialty topics are introduced to the class– These are integrated into the “six segment story” at logical points


How is the course structured?(Cont.)

Actual course content will be presented here.

• The next few slides present– The introduction to the “six segment story”– The presentation of Segment #2

• The class will conclude that an investigative test needs to be performed– They will identify the basic characteristics of a properly

performed test.– They will then review those same characteristics in Criteria

XI and XII


Examination of Individual Power Plant Settings

• We will examine a typical “story”– Unfolding one scene at a time

• For each “scene”, we will:– Identify what needs to happen next

– What a successful outcome will look like

• Review the applicable Quality Criteria from Appendix B– Highlight summary statements

– Identify other key points and inter-relationships

This slide introduces

the “six segment story”.


Segment #1

During the current refueling outage, an inspection of the Main Control Room Heating, Ventilating, and Air Conditioning System (MCR HVAC) has identified warped seats on the outside air isolation damper. A quick leak test of the seats demonstrated that they were clearly no longer leak-tight.

An evaluation of the leakage’s impact has been performed and the MCR HVAC has remained Operable, but just barely.

This is the second outage in a row that the damper’s seats have been found warped. The previous outage the warpage was attributed to normal wear and the seat was replaced.

What actions or activities are needed?

This is the initial problem description.

We will proceed directly to Segment #2.


Segment #2

As part of the Formal Root Cause Investigation, the following facts have been identified.•The damper’s warping appears to be due to a differential, or shear, stress having been induced between the inner and outer seating surfaces•The damper/seat design has not been altered since initial construction.•No failures have been observed prior to the last two outages•A new surveillance to stroke test/time the dampers was initiated three years ago.

•This test automatically actuates and times the dampers from all possible signals

Because of this information, the performance of the surveillance has come under scrutiny.

What actions or activities are needed?

The class is coached/helped to

answer this question, as

needed.


Major Actions Required for Segment #2

• The details of the surveillance test needs to be examined

• An investigative test or inspection may be conducted

• The measuring devices must produce reliable information

A technical discussion of Segment #2 will result in the class identifying the activities on this slide.


Actions Required (and their attributes)

Actions/attributes

• The details of the surveillance test needs to be examined

• An investigative test or inspection may be conducted

– Measuring devices will be used• e.g. strain gauges, RTDs,

etc

• The measuring devices must produce reliable information

Appendix B Criterion

• Criterion 11– Test Control

• Criterion 12– Control of Measuring and Test

Equipment

The class will have identified these.

They will be told of the existence of the corresponding Appendix B

requirements.


Criterion XI. - Test Control

A test program shall be established to assure that all testing required to demonstrate that structures, systems, and components will perform satisfactorily in service is identified and performed in accordance with written test procedures which incorporate the requirements and acceptance limits contained in applicable design documents. The test program shall include, as appropriate, proof tests prior to installation, preoperational tests, and operational tests during nuclear power plant or fuel reprocessing plant operation, of structures, systems, and components. Test procedures shall include provisions for assuring that all prerequisites for the given test have been met, that adequate test instrumentation is available and used, and that the test is performed under suitable environmental conditions. Test results shall be documented and evaluated to assure that test requirements have been satisfied.

The class reviews the actual

requirement...

and relates it to the required actions they have identified.


Criterion XII. Control of Measuring and Test Equipment

Measures shall be established to assure that tools, gages, instruments, and other measuring and testing devices used in activities affecting quality are properly controlled, calibrated, and adjusted at specified periods to maintain accuracy within necessary limits.

The same pattern shown on the

previous slide for Criterion XI is

repeated.


Criterion XII versus Criterion XI

• Some criterion are more complex

• Some criterion support other criteria– Related to a “barrier view” of event prevention to be discussed later

• Control of Measuring and Test Equipment (XII) supports Test Control (XI)– Test Control requirements are more complex

• Includes “adequate test instrumentation is available and used”

– Control of Measuring and Test Equipment requirements are simple and direct

• “maintain accuracy within necessary limits”

The manner in which the various criteria work

together is highlighted throughout the course.


Major Points for Segment #2

• Nuclear Power Plants have to test SSCs for a variety of reasons

• Criterion XI requires– A test program

• governed by procedures related to design requirements

– with specific features/characteristics

• Criterion XII supports Criterion XI (among others)– “maintain accuracy within necessary limits”

• instrumentation calibration is a separate I+C sub-task

Each Segment is summarized before moving on to the next.


The preceding slides are indicative of the course’s level of detail.
