The possibility the 'A' MFRV failing shut presents the possibility of tripping the plant.
Even at the reduced power level, the Bypass valve is not capable of supplying sufficient feed, thus if the MFRV fails closed the plant will eventually trip (either on SF>FF mismatch w/ Lo SG Level or Lo

IF the (KT) process is employed, THEN it shall be performed by personnel trained in the (KT) process.2.0SCOPE2.1The procedure scope includes:*Power Block equipment failures/malfunctions where there is a potential impact on continued plant operation.*Power Block equipment failures/malfunctions where previous corrective actions have NOT successfully prevented recurrence.2.2Actions taken to correct a specific known problem are NOT considered troubleshooting and are NOT within the scope of this procedure.2.3This procedure addresses the physical cause of an equipment failure/malfunction. This procedure is NOT intended to address Human Performance issues or replace a root cause analysis required by the corrective action program. Although there is overlap between root cause and troubleshooting in determining what to fix, in general, troubleshooting is the process applied to determine "What" to fix and the corrective action program is used to determine "Why" it failed.
DOMINIONMA-AA-103REVISION9PAGE 4 OF 37INFORMATION USE3.0INSTRUCTIONS3.1General3.1.1During each step of systematic approach to troubleshooting, CONSIDER whether it is still acceptable to continue system or plant operations based on significance of deficient condition.3.1.2During development of trouble shooting plans, REVIEW WM-AA-301 for operational risk assessment. (Ref.5.4.12)3.2Problem IdentificationInitiator3.2.1CONSIDER the following examples of information during troubleshooting activities, and DOCUMENT initial conditions for use by the Troubleshooting Team (TT) in the WR/CR/WO, as appropriate: *Evidence or data preserved during the course of the investigation*Videotape or photographs of the scene as appropriate*Frame of reference for photographic evidence (ruler, etc.)*Identifying labels in photographic evidence
- Labeled component saved for future analysis and reference*Sketches including scale when possible*Initial and final condition and location/state of all items found
- Conditions in the environment such as spray, heat, direct sunlight or unusual odors*Out of ordinary conditions*Description of equipment condition when found including unusual or unexpected conditions of equipment as well as surrounding equipment andarea NOTE:Particular attention is required when troubleshooting has the potential to impact design function of any structures, systems, or components that are being relied upon to support plant operation or achieve and maintain safe shutdown.
NOTE:Subsections 3.2 and 3.3 are typically performed by the Operating crew and those first responding to the concern. After the Troubleshooting Team (TT) has been formed, the TT should ensure Subsections 3.2 and 3.3 satisfactorily completed.
NOTE:The Operating crew and shift personnel may have already completed Subsection 3.2 prior to a Troubleshooting Team Lead (TTL) or a TT. Therefore, the TTL or TT may confirm Subsection 3.2 completion with the Operating crew and go to Subsection 3.3.
DOMINIONMA-AA-103REVISION9PAGE 5 OF 37INFORMATION USE3.2.2CONTROL the area (i.e., isolate or quarantine area, if possible).3.2.3IDENTIFY unusual or unexpected conditions of equipment as well as surrounding equipment and area.3.2.4MAINTAIN parts in the area until location, orientation and condition arenoted.3.3Initial Problem Statement3.3.1DOCUMENT the WR/CR/WO, system, component ID, operating conditions, initial problem statement and the initial Risk Number and Rigor Category on Attachment 2, Troubleshooting Sheet.3.3.2ASSIGN a Troubleshooting Team Lead (TTL) for both simple or complex troubleshooting activities and document the name on Attachment 2, Troubleshooting.
DETERMINE if a multi-disciplined troubleshooting team needs to be formed. In most cases the troubleshooting may still be led by Maintenance with support from Engineering or other work groups.Troubleshooting Team Lead (TTL)3.3.3DEFINE clearly the problem before proceeding with troubleshooting. Understand the scope and nature of the issue, identify the severity of the problem, and establish to what extent the problem has been observed in the plant or system.
NOTE:It is NOT appropriate at this stage to speculate about the source of the problem or offer corrective actions. Experience suggests that defining the problem is the most important step in the process. Problem definition is essential for implementing the troubleshooting process in an efficient manner, following a structured approach, and finding the right solution to the problem the first time. A preliminary evaluation must be performed to gain a clear understanding of the issues. The problem statement is to address: who, what, when, where and NOT why.NOTE:Plant Manager will assign the Troubleshooting Team Lead (TTL) on a I-High Risk troubleshooting team. The Maintenance Manager will assign the TTL for a II-Medium Risk troubleshooting team.
NOTE:In most cases, the technical or maintenance expert should NOT serve as the TTL. Such experts should be allowed to apply full attention to plan development and implementation rather than be distracted by coordination details and administrative responsibilities.
NOTE:For the large majority of troubleshooting, which involves simple, non-complex problems, the TTL is the Maintenance First Line Supervisor in charge of the task.
NOTE:For simple troubleshooting the WR/CR/WO may suffice as the initial problem statement. The scope of the troubleshooting activity may pose a high risk to plant operation. The more risk significant the troubleshooting, the more rigorous the controls applied.
DOMINIONMA-AA-103REVISION9PAGE 6 OF 37INFORMATION USE3.3.4DEVELOP a problem statement that is technically correct and detailed as possible. A face-to-face interview with the personnel communicating the performance issue, especially operators, should be performed.
TTL3.3.5 LIST employees who identified or are knowledgeable of the problem on Troubleshooting Sheet (Attachment 2).3.4Determine Level of Support TTL3.4.1DETERMINE if a complex troubleshooting plan is needed to perform the troubleshooting activity and DOCUMENT on the Troubleshooting Sheet (Attachment 2).3.4.2 IF any of the following questions are answered YES , THEN complex troubleshooting is required or may be deemed complex troubleshooting at management discretion.
- DOES activity require involvement from more than two groups/disciplines?*WILL the activity require numerous attempts in order to resolve?*WILL the same component require multiple condition reports in order to resolve the same/similar issue?*DOES the activity pose a potential operational risk?*DOES the activity of sufficient complexity require specialized personnel (i.e. vendors, corporate engineering,...)?*DOES troubleshooting deem complex troubleshooting at management discretion?3.4.3 IF troubleshooting has been identified as Complex Troubleshooting, THEN OBTAIN manager level approval of the problem statement.
EXAMPLE: Good: "On 6/6/98 at 1500 while in Mode 1, Containment Isolation Valve (V-216), located in the Unit 2 penetration room, failed its IST stroke test by 1 second, during a preplanned surveillance. Its design basis closing stroke time is 10 seconds and its tested stroke time was 11 seconds. Failure of the valve to perform its function puts the station in a 72-hourLCO."
Bad: "Containment Isolation Valve broke/fix."
NOTE:Complex troubleshooting requires gathering data for extensive engineering analysis, or may significantly affect production/safety risk margins. Step3.4.2 provides questions that should be used to aid in determining the need for a complex troubleshooting plan.
DOMINIONMA-AA-103REVISION9PAGE 7 OF 37INFORMATION USE3.4.4 IF a troubleshooting team needs to be formed, THEN PERFORM the following to form the team:Operations or Maintenance Manager a.ENSURE the troubleshooting team's composition includes individuals trained and experienced in troubleshooting techniques (e.g., KT problem analysis process, failure mode/cause analysis) b.IF applicable, THEN ESTABLISH a technical lead.
TTL c.IF the plant challenge is an immediate attention item requiring around the clock work, THEN IDENTIFY relief personnel to support coverage.
d.CONSIDER involving resources from Operations, Engineering, Maintenance, other stations, Corporate Engineering, Vendors, O&P, etc., as required.

NOTE:A troubleshooting team shall be used for:*Solving higher risk or complex troubleshooting problems.*Troubleshooting activities which pose significant challenges to the plant such as short duration LCOs that would result in a unit shutdown.*Any event which threatens the on-line status of a unit.
- Other significant equipment problems as requested by Engineering, Maintenance, or Operations Managers.The troubleshooting team can vary from a worker and supervisor (with Outage and Planning support) to a multi-department team, depending on complexity of problem. For the large majority of troubleshooting, which involves simple, non-complex problems, the TTL is the Maintenance First Line Supervisor in charge of the task.It is recommended that members be assigned from Maintenance, Engineering, and Operations at a minimum. Other groups may be assigned as required for the task.
NOTE:The technical lead will normally be the system engineer, component engineer, program engineer, or subject matter expert from maintenance. The TTL should NOT be the technicallead.

The need to quarantine equipment should be considered per OP-AA-1300,Quarantine.
NOTE:To the extent practical, acquiring information should precede any hands on troubleshooting.
NOTE:Troubleshooting involves use of a systematic approach to find the cause of a problem. The KT Problem Analysis and Complex Troubleshooting Failure Mode/Cause Table (Attachment 4) are tools used with the goal of getting to problem resolution in the quickest and easiest fashion based on the training and experience of the personnel involved. If employing the use of KT Problem Analysis, then Attachment 4, Complex Troubleshooting Failure Mode/Cause Table of this procedure is NOT required, however both may be used at the discretion of the TTL.

b.PERFORM KT Problem Analysis and DOCUMENT the analysis using the KT Problem Analysis forms.c.Once actions to confirm true cause have been developed, attach a copy of the KT Problem Analysis form to Attachment 2, Troubleshooting Sheet, Page 1.NOTE:The team should understand the design and operation of the system/components prior to listing possible failure modes. Correct terminology should be used when referring to structures, systems, or components (Slang terms, abbreviations, and acronyms can be used if defined in the document).
DOMINIONMA-AA-103REVISION9PAGE 10 OF 37INFORMATION USE3.7Develop Troubleshooting Plan3.7.1DETERMINE if any alterations (i.e. Temp Mod) made during the troubleshooting process or installation of monitoring (M&TE) equipment require additional reviews (i.e. Modification, 50.59 Applicability Review, etc.). 3.7.2DETERMINE if detailed work instructions already exist for troubleshooting activity in procedures or work order.3.7.3 IF detailed work instructions are needed, THEN PERFORM the following:
a.ENSURE there is adequate instructions and precautions taken when the activity is performed to minimize the risk to the reliability to the plant. b.Based on the level of detail needed to perform the desired troubleshooting activity, INCLUDE detailed work instructions in Troubleshooting Sheet (Attachment 2), page 2.
NOTE:Since troubleshooting plans may require that systems or component remain energized to fully determine the problem, particular attention is required to determine the impact of the troubleshooting on the rest of the plant. Actions necessary to minimize impact on the plant need to be determined to prevent creating an undesired or unanalyzed equipmentconfiguration.These actions could be as simple as closing a valve to prevent undesired flow changes, placing a component in "bypass," or complying with Technical Specification LCOs. The actions could be considerably more complex requiring review of minimum required inputs to a trip channel, identifying interlocks with other components, or assuring that design functions described in the UFSAR are not compromised.
NOTE:Each troubleshooting plan will be different, based on the type of system, the severity of the observed problem, the failure modes identified, and the potential effects of the failure modes on system performance. Level of plan detail and associated approval authority is dependent on risk, the rigor of the troubleshooting activities, and the significance of thefailure. Operational risk is assessed in accordance with WM-AA-301, Operational RiskAssessment.
NOTE:Design functions of structures, systems, and components (SSCs) being relied on to support plant operation or achieve and maintain safe shutdown could be adversely impacted by the troubleshooting activity.

(Attachment 2)3.8.6IDENTIFY any decision or stop points to evaluate progress or subsequent actions. (Attachment 2)
NOTE:Detailed work instructions may not require a complex troubleshooting plan. Detailed work instructions are required for activities that pose a specific level of risk to the plant due to the system being worked on and the type of activity. Consider the potential for impact on the design functions of SSCs being relied upon to support plant operations or the ability to achieve and maintain safe shutdown.If detailed specific instructions are required, develop work instructions based on known evidence with guidance from plant engineer, vendor, or other technical experts asappropriate.
NOTE:The very nature of equipment failures creates the possibility that design logic is no longer valid. Consideration should be given to new or unanticipated design logic that could have been created by the failure.

A team may also be formed for significant challenges such as a short-duration LCO when initial troubleshooting activities were unsuccessful or at management's discretion. The size and makeup of the team will be driven by the needs of the station and business decisions of station management.5.3.7Troubleshooting Team Lead (TTL)Individual responsible for overall condition of the troubleshooting activities and communication to the management team. For lower risk activities, the individual is the first-line supervisor. For higher risk activities where a troubleshooting team is assembled, the individual is an engineering supervisor or a maintenance second line supervisor.

2.Review activity matrix on page 3 to determine the rigor category if the troubleshooting steps fall within examples provided or similar actions.3.If applicable, utilize the category list on page 4 to include the level of rigor in the plan details and involvement of the personnel to minimize the risk to plant systems and personnel.ATTACHMENT1(Page 1 of 4)Risk and Rigor Determination Matrix DOMINIONMA-AA-103REVISION9PAGE 23 OF 37INFORMATION USEGuidelines for Level of RISK DeterminationI. HIGH RISK:Equipment is not removed from service. Presents a risk of tripping the plant, actuating a safety system, causing a significant reactivity change, or possible radiation release, either directly or as a result of causing a major plant transient.II. MEDIUM RISK:Equipment is not removed from service. Could result in an undesirable plant transient, affect reactivity, or a reportable event, but not a reactor trip or safety system activation.III. LOW RISK:Equipment is not removed from service. Could have an affect on plant equipment, but should not present a risk of causing an undesirable plant transient, reactivity change, or reportable event. No unusual personnel safety risk.IV. NO RISK:Equipment is removed from service. Troubleshooting activities do not affect the operation or safety of the plant.
EXAMPLE:Removing an instrument loop from service in a high-Risk classification was classified as a Category "A" activity. Once the loop is out of service and the device is in the shop, it can be moved to a lower risk classification.

It is not expected that Protective Action Recommendation (PAR) development be delayed by attempting to obtain information from outside resources.PAR NOTIFICATION TIMES:The initial PAR must be included with th e initial notification of a General Emergency, which must be made to the State within 15 minutesfollowing declaration of the General Emergency.Notification of a revised PAR must be made to the State within 15minutes of its development.SECTORS/WIND DIRECTION
- Downwind sectors may be determined from Attachment 4, Downwind Sector Table.Wind direction is always given in degrees from.SHELTERING INPLACE:There is no dose threshold for recommending sheltering-in-place.Sheltering-in-place may be recommended as a result of controlled releases, evacuation impediments or other known conditions which make evacuation dangerous.A controlled release is a short-term release, which is a controlledevolution and the release duration can be accurately determined (such as containment venting).PREVIOUSLYISSUED PAR:Previously issued Protective Action Recommendations should not be reduced until the threat is fully under control and after consulting with Commonwealth of Virginia emergency response organization.
