6. PROCEDURE ~

6.1 Maintenance work control general concepts and requirements The objective of maintenance work control is to maintain the safe and efficient operation of the plant. The key elements of the control process are as follows:

1) Timely identification _of tasks

2) Thorough planning of the work

3) Appropriate priority determination and careful integration of the work into the Station schedule

4) Control of plant equipment by the Operations Shift Supervisor at all times

5) Correct performance of the work and completion of required inspections and tests

6) Accurate and appropriate status assignment and tracking

7) Consistent records accumulation and storage.

The Maintencnce Work Order (MWO) (Enclosure 2) is the document which represents each task within the control system. Each step in the process is documented on the MWO. After the task is completed the MWO,' and the work, test, and inspection. records associated with it, become a part of the configuration and equipment history record for the plant. The MWO is used to provide the written authorizations for control of maintenance work. It becomes the

.auditable record of the control of work. Enclosure 7, Work Control (MWO) Flow Chart, illustrates the basic steps involved in the normal work control process.

A computer based system is used to maintain information about equipment and ongoing maintenance work in the plant. It is called the Davis-Besse Maintenance Management System (DBMMS). It provides convenient storage and retrieval of information about maintenance tasks and about equipment in the plant.

An important exception to the normal processing of tasks within the i control system is "immediate maintenance action". The Operations

! Shift Supervisor has the authority and respo'sibility n to direct j immediate action by maintenance personnel when it is required to

AD 1844.02.0 Page 12 of 51 i

l 6.1 (continued) t ensure the safe operation of t.he plant. No provision of this procedure shall be interpreted or used to limit the ability of the Operations Shift Supervisor'to perform such immediate maintenance work.

Subsections 6.2 through 6.15 detail.the requirements to be met for tasks which are processed normally. The control of work shall be ,

the same for both maintenance and modification work. For modification work, the duties of the planner / scheduler and maintenance coordinator shall be performed by the modification coordinator. The Facility Modification Manager serves as the Planning Manager for these tasks. The additional requirements

.which apply to modification work are detailed in Facility Modification Procedures. Subsection 6.16 specifies the require-ments for work performed as "immediate maintenance actions".

Additional general requirements which apply to work performed on plant equipment are listed in 6.1.1 through 6.1.4.

6.1.1 The DBMMS shall be used for generation and tracking of Maintenance Work Orders (MW0's). Manual generation and tracking is permitted whenever the DBMMS is unavailable.

When manual MWO processing is necessary, the Document Control Group shall assign MWO numbers and maintain a log of such MWO's until they can be entered into the DBMMS.

Planning and scheduling personnel shall monitor tasks in progress and maintain a current status code on the DBMMS system for each MWO. The status codes are detailed in Enclosure 8.

6.1.2 Generic MWO's may be generated to control maintenance work of a repetitive nature (such as changing light bulbs). The MWO remains active for a specific period of time, normally three (3) months -- not to exceed one-year; and work will be performed against it in response to work requests generated during that period.

6.1.3 During the implementation of a MWO, changes to the MWO may be needed. Such, change ~s may be made provided that each entry changed receives the same reviews and approvals as required for initial entry of the item. For all other changes the Planner shall ensure that required "re-approvals" have been granted prior to resumption of the work.

In the specialicase of changing the scope of the MWO, i.e. the equipment addressed and/or the tasks to be performed, additional means must be provided to ensure the control of the work. Such scope additions must be made on MWO continuation sheets and places for approval signoffs must be provided~for the Planning Supervisor, the Shif t Supervisor and where applicable, QC, the Code Inspector and the Maintenance Coordinator.

AD 1844.02.0 Page 13 of 51 6.1.4 Whenever MWO processing may not proceed while some support activity is being performed, the MWO will be placed on " HOLD" status. Enclosure 8 lists the various

" HOLD" status codes. When on hold, MWO's which have been printed whall be forwarded to the Document Control Group for filing. Planning, Maintenance, QC and Operations may place MWO's on hold. The individual who assigns the

" Hold" status shall immediately advise the Planner when the need for a " hold" is determined. The Planner shall advise the Shift Supervisor of all " Hold" status assignments for MWO's which affect nuclear safety related equipment. The Shift Supervisor's concurrence is required for placing such MW0's on hold.

6.1.5 A MWO may be " voided" if no actual work has been performed. The Planner or Maintenance. Shop Foreman may write " void" in Block 15 (Work Completed) of the MWO and entering the reasons for voiding the MWO in the

" Description of Work Performed" Section of the MWO --

Personnel / Equipment History Form. (Enclosure 4)

The " voided" MWO shall be then routed through those individuals who have signed it for acknowledgement or approval. It shall then be filed as a completed MWO.

6.1.6 The processing of work control documents shall be performed in a manner consistent with the urgency of the work. The Shift Supervisor's assignment of priority to tasks takes precedence over any other priority assignment.

6.1.7 The latest revisions of applicable procedures shall be used in the performance of maintenance work.

1. When revisions or modifications to procedures are received by the DCG, they shall determine which, if any, MWO's which have been sent to Maintenance for implementation require (list) the' revised procedure.

The DCG shall send written notification of the procedure revision or modification to the Lead Shop General Foreman identified for the MWO's which require the procedure. They shall also send copies of the revised procedure if a copy will be required in the field to do the work.

2. The Lead Shop General Foreman shall attach such copies of revised procedure or modification to the-affected MWO packages and discard any superseded copies. He shall ensure that the Shop personnel are made aware of such changes to procedures. He shall acknowledge his receipt of the revised procedures or modifications to the DCG by signing, dating, and returning the notification.

AD 1844.02.0 Page 14 of 51 6.1.7 2 (continued)

3. If the work cannot proceed without resulting in a violation of the revised or modified procedure, the foreman shall place the work on " hold" and. advise the Maintenance Coordinator of the problem. When the problem is resolved, the MWO may be returned to active status and work may proceed.

6.2 Maintenance Task Identification Maintenance tasks are identified from three basic sources; Preventative Maintenance Schedules, modifications to the plant and conditions to be corrected.

6.2.1 Preventa'tive Maintenance (PM) tasks are defined and scheduled per AD 1844.01, Preventative Maintenance. The-PM Specialist uses the DBHMS to produce the appropriate task descriptions for each time period based on the PM schedule stored in its data base for the equipment.

6.2.2 The tasks required to make modifications to the plant are identified in Facility Change Request (FCR) packages.

The FMD Modification Coordinator shall identify the tasks

.to be performed to implement each modification.

6.2.3 -Nonconformance Reports (NCR)

Nonconformance Reports (NCRs) shall be issued in

.accordance with Section 15 of the Nuclear Quality Assurance Manual (NQAM), "Nonconformance". The disposition of a NCR shall. initiate a MWO when the NCR disposition is " repair" or " rework." The QC Organization shall forward the NCR to Planning or the Facilities Modification Division for initiation of'the MWO.

6.2.4 QC Surveillance A QC surveillance of work being performed may result in an unsatisfactory Surveill nce Report for discrepancies not requiring a NCR. The resolution of the Surveillance Report may require a MWO. The personnel responsible for disposition of the report shall forward it to Planning

.for initiation of a MWO.

AD 1844.02.0 Page 15 of 51 6.2.5 Quality Assurance (QA)

QA Audits may result in findings which require the performance of maintenance work for resolution. Audit Finding Reports (AFR) shall be issued in accordance with NQAM Section 18, Audits. Such AFRs may initiate an MWO.

The department responsible for the response to the AFR shall route a copy of the AFR to the Planning Supervisor for initiation of the MWO.

6.2.6 Deviation Report (DVR)

Deviation Reports shall be issued in accordance with AD 1807.00, Control of Conditions Adverse to Quality.

Depending on the conditions identified; a MWO may-be generated to correct the condition. The department responsible for the resolution of the deviation shall forward it to Planning for initiation of a MWO.

6.2.7 The work request (WR) is the most frequently used method for identifying needed maintenance tasks. This document is used to record initial information about needed tasks, to record the approval of the task by supervisory personnel, and to input the task into the planning, scheduling, and implementation process.- The kB shall be used for identifying all tasks not identified by one of the processes discussed in 6.2.1 - 6.2.5. The1 originator of the WR shall generate the request as detailed in 6.2.7. In addition, the WR originator shall hang a Maintenance Information Tag (Enclosure 11) on the equipment addressed in the WR. The instructions included in Enclosure 11 shall be followed for tag completion and hanging. Either of two means may be used to generate the work request: 1) Use of a hard copy form (Enclosure 1) to record the required information and approvals; 2) Use the DBMMS to input the required information into a WR record. When this means is used by the Shift Supervisor, Planning shall consider the WR " approved" and process it accordingly. If the hardcopy means is used, the originator's supervisor shall review the request. He shall sign the request (Part 14) and forward it to Planning if he approves it. If he disapproves it, he shall return it to the originator. Upon supervisor approval, he shall forwa'rd the k1 to Planning. The Planning Staff SRO shall consult the operations coordinator as appropriate and assign the priority and schedule weight. A Planner shall then initiate a MWO for the work.

6.4 Maintenance Work Plan Development 6.4.1 For corrective action maintenance the Planner shall perform appropriate walkdowns, review the P& ids, drawings, procedures and vendor manual (s), and identify corrective actions and necessary documentation for the task. The intent of this procedure is that the scope of a MWO shall not be changed once it was been approved.

Separate MWO's shall be developed for " troubleshooting" or " investigation" and corrective actions. He shall review the proposed work plan with Maintenance, Quality Engineering, Quality Control, Technical Support, and Operations personnel, as needed, to develop the plan.

6.4.2 The Planner shall determine the quality classification of the equipment and activities addressed in the MWO. He shall use Q List (Appendix B of the NQAM) as a "first resource" to make this determination. When the classificativa is not clearly defined in the Q List, he shall contact the Facility Engineering Department for assistance. The Facility Engineering Department shall provide the Planner with classification.

The Planner shall contact Facilities Engineering and they shall advise whether or not the equipment requires Environmental Qualification (EQ).

The Planner shall determine, with help as needed from the Fire Protection (FP) Coordinator, whether or not the equipment is Fire Protection System (FPS) equipment. If the equipment is FPS equipment, or if the work will affect FPS equipment, the FP Coordinator shall request an evaluation by Facility Engineering to determine the

" Operability" of the system during performance of the work.

The Planner shall determine which, if any, other codes, such as ASME, apply to the work addressed on the MWO.

They shall request assistance from Facility Engineering.

6.4.3 For tasks to be done in Radiation Controlled Access Areas (RACA), the Planner shall present the plan to Chemistry &

Health Physics (CHP) supervisory personnel for ALARA review and designation of Radiation Exposure Permit (REP) requirements. If a REP is required, the Planner shall initiate the REP and advise C&HP of when it will be needed. C&HP shall advise the Planner whether the REP will be ready when needed or if problems need resolution.

l

AD 1844.02.0 Page 21 of 51 6.4.4 The Planner shall determine those procedures which are required to perform the work. Maintenance procedures or

~

reference to vendor manuals which have been approved in accordance with AD 1805.00 are required for work on Q1 or Q2 equipment. If no procedures are required, i.e., the work may be done as " skill-of-the-craft" per AD 1844.00, the Planner shall indicate this in Block 4 on the MWO.

6.4.5 In addition to specifying those procedures or other approved instructions which are required to perform the work, the Planner shall also specify which major sections in the body of the procedure (s) are to be performed. A statement to this effect shall be entered in the MWO. If the procedure (s) or instructions are to be performed in their. entirety then the major sections to be performed need not be specified. iIf one section of the body of the procedure directs the reader to another section(s) of the procedure under certain conditions that may arise during the conduct of the work in the field then this other section(s) should also be listed on the MWO with the section number followed by "(as required)". If there is any uncertainty on the part of the Planner as to which major sections of a procedate(s) are to be performed.under a given MWO, then he shall obtain clarification from the Maintenance Department staff or shop foreman. Although an MWO may state that only certain sections in the body of a procedure (s) are to be performed, all other sections outside of the body of the procedure including PURPOSE, DEFINITIONS, FRECAUTIONS AND LIMITATIONS, PREREQUISITES, etc., still apply.

6.4.6 If required, the Planner shall initiate a Temporary Mechanical Modification Form per Procedure AD 1823.00.

6.4.7 The Planner shall determine whether review of the MWO by an individual who holds or has held a Davis-Besse Senior Reactor Operator (SRO)' license is required. For work on shop equipment or pre-fab work, such SRO review is not l

the work is' ready to be performed.

For work that does not.have any effect on plant systems or operations, such as work on shop

equipment or prefab work, the shop foreman shall

. sign this block or obtain the Shift Supervisors

! sign-off in this block.

For all other MWO's, the signature of the Shift Supervisor is required in order to begin the mainte-nance. This signature indicates the equipment is i

properly aligned for the maintenance, tags are

. properly placed, and plant conditions permit the work. If an Enclosure 13 is required with the MWO the " Pre-Maintenance" portion of the Enclosure 13 shall be completed prior to this signature being

. entered.

! The Shift Supervisor may authorize the work activity

. prior to the hanging of the Jumper, Lifted Wire,_or I-Temporary Mechanical Modification Tags. Electrical Jumper, Lifted Wire or Temporary Mechanical Modification Tags may be issued after-the work activity has begun. This will enable the individual performing the work activity to determine which tags will be required to perform the Maintenance Activity. NO wires may be lifted, Electrical Jumpers or Temporary Mechanical Modifications installed until the provisions of AD 1823.00,

" Jumper Lifted Wire Control Procedure", have been met.

'not previously done.

3. Inspectors.shall not sign this block until any NCR's i

or Surveillance. Reports affecting the' equipment operability are satisfactorily dispositioned.

QC shall place a check in Block 27 if a NCR has been written against the work or testing addressed in the

MWO. They shall also enter the number of the NCR in 1 the space provided.

Satisfactory disposition of any NCR shall be indicated in Block 27 by the appropriate checkoff.

This checkoff will be performed by the cognizant individual.

3 NOTE A completed NCR is defined as a NCR which:

a. .Is indeed. closed and satisfactorily signed off with the appropriate i

signatures;

b. Has been dispositioned "use as is" and i does not affe'ct a safety function; or

c. 'Is dispositioned "use as is, temporarily",

i.e., a safety evaluation, performed by cognizant engineering personnel, has i determined that the equipment addressed by the NCR will perform its safety function when returned to service with follow up maintenance to be performed.

If a NCR.was not written the appropriate chece. offs

will be made in Blocks 25 and Block 27.

4. If parts of the work were not satisfactory, and nct reworked under the same MWO as punch list items on a continuation sheet, a follow-up MWO as agreed by the Inspector and appropriate maintenance supervision is required. The. Inspector's signature shall not be

, entered until a follow-up MWO has been initiated the same testing requirements and the follow-up MWO number has been entered in the appropriate box in Block 27.

I 60 AD 1844.02.0 Enclosure 6 Page 1 of 2 NPRD Form Instructions

-G neral Instructions NUREG 1022 recuires that a report be submitted to the Nuclear Plant Reliability Data System (NPRDS) for all failures of certain plant systems and equipment, which are listed in the reportable scope. The Enclosure 5 NPRD form is used by the Station to idrntify that such a failure occurred, and to forward information to the Nuclear Raliability section. When Nuclear Reliability is made cognizant of a failure, it is their responsibility to prepare a detailed report using the Enclosure 5 information, cad other data sources, to tne NPRDS data base which is operated by INPO.

Detailed Form Instructions

1. The individuals in Planning and Scheduling who prepare the MWO's shall deter-mine reportability by reviewing the NPRDS Data Base listing. If the component or system appears in the listing, indicate-in Block 27 on the MWO. when a failure is known, mark "YES" as appropriate.

NOTE: Although the DBMMS may indicate NPRD reportability on MWO, the DBMMS Equipment Data Base is not accurate. Therefore, the NPRDS Data Base must be reviewed for verification or reportability.

2. If the equipment is reportable, an NPRD Form shall be attached to the MWO by Planning.

3. Effort should be made to complete the NPRD Form immediately in the field if adequate information is available. In some cases, completion of the form may have to wait until the maintenance is complete and/or a review of the work performed including an evaluation of the failure mode can be performed.

4. The person completing the NPRD Form shall enter or circle the appropriate data for the heading and Romaa numberal items I through VII- and sign for the form's completion. Additional 4 ssistance can be obtained by use of the NPRDS Report-ing Procedures Manual. Section 5 of this manual explains and defines the reporting codes listed on the NPRDS Form. A copy of this manual is available in Nuclear Reliability and the Tech. Library.

5. During MWO close out, Document Control shall route the NPRD Form to the System Engineer for review. The System Engineer, or Alternate, is ultimately respon-sible for ensuring the NPRD Form is completed properly.

6. If the NPRD Form is completed in the field, that person shall sign the

" completed by" block. The System Engineer, or alternate, shall review the form to ensure its completeness and accuracy and sign for its approval. If the System Engineer, or alternate, completes the NPRD Form, both places shall be signed by that person.

61 AD 1844.02.0 Enclosure 6 Page 2 of 2

7. The NPRD Form shall be included in the MWO package routed to Planning for closeout. Document Control shall forward a copy of the form to Nuclear Reli-ability for additional reviev and further action.

8. Nuclear Reliability shall review the NPRD Form. If a failure is verified as reportable, then the associated work request, MWO, any DVR's or LER's, are compiled with other appropriate data in the final NPRDS failure report. The-NPRDS failure report is then forwarded to INPO for final processing and inclusion into the industry NPRDS data base of failure reports.

QUESTION NO. 6 4

2 Are any in-situ tests planned prior to restart utilizing line flaid' flow (s).in which th'e valves must close?

RESPONSE TO QUESTION NO. 6 No. Toledo Edison considers requiring a valve to open against high differential pressures to be the most severe condition of service, and a i bounding condition for testing. Delta P testing utilizing line fluid flows is restricted by plant conditions. Toledo Edison is performing limited testing using line fluid flows where the valve is required to t

open. SW 1379 has been successfully tested using line fluid flow. AF3870 was also successfully tested utilizing partial fluid flow (restricted by plant conditions).

QUESTION NO. 7A Are any in-situ tests utilizing delta P's and/or fluid flow planned on an ongoing basis?

RESPONSE TO QUESTION NO. 7A Currently no in-situ utilizing Delta P's or fluid flow are planned on an ongoing basis. Any in-situ testing utilizing delta P'.s and/or fluid flow conditions would appropriately be reflected in Surveillance Testing or the

In-Service Testing programs. The Surveillance and Post-Maintenance Testing Procedures are being reviewed to determine if this testing or portions thereof can be performed at expected operational differential pressures.

Toledo Edison will initiate. procedural.and programmatic enhancements as 4

. appropriate once this review is completed.

QUESTION NO. 7B Ongoing MOVATS, etc?

RESPONSE TO QUESTION NO. 7B Toledo Edison has indicated intent to perform full Motor Operated Valve Analysis and Testing System (MOVATS) testing of Nuclear Safety Related valves approximately every three outages to Region III (as document'ed in November 21, 1985, telecon attached). For certain corrective maintenance activities on a Limitorque actuator, MOVATS is procedurally required. The means by which MOVATS testing will be used as a predictive maintenance tool is under evaluation. Criteria for this use (such as periodicity, action levels, etc.) cannot be prescribed until further data and experi-ence is obtained.

SUBJECT; Recommendations presented to TED during a recent inspection regarding testi.ng of motor operated valves.

TED agre'ed with P. Wohld that the ASME code is deficient when it comes to identifying degradation of MOVs. To 1. ave a more meaningful test, TED plans to perform required ASME stroke time testing by using either MOVATS or a brush recorder at the MCC. We would also take other data s'ach as running current and voltage. Based upon dis-cussions with Limitorque, the normal running current provides the best indication of valve degradation. E. Caba indicated that we would not have any acceptance criteria b: sed upon running current, but we expect to trend this value for degradation. At the

earlier meeting, P. Wohld had recommended that if a 2% change in stroke time was recorded, then some action would be taken. E. Caba indicated that TED felt this was too stringent bssed on discussions with Limitorque and that a 10% change in baseline would be a flag l that further evaluation of the value would be required (possibly a full MOVATS run).

1 P. Wohld indicated he was looking for some technically sound values and would like to i sie a more conservative number. After further discussion we agreed that there was probably not ennegh data to support establishing a technically sound % change in stroke times. This

% chage would be established by TED following an evaluation once a sufficient data base is cvailable. (Cont. on pg. 2)

E. Caba then questioned whether TED needed to provide some alternative iustification for our current mode of- testina. P. Wohld indicated additional justification w== nat reanirad ha-ccuse our testing is more conservative than the ASME Code. E. Caba also indicated that TED planned to do full MOVATS te-tina of Nuclear Safety Related valves accroximatelv everv third refuelina outage.

E. Caba then indicated that it was TEDS intent that those valves that have alreadv_ been MOVATS tested and are required to be retested per ASME code reouirements durina the current cutase, we would be usina the stop watch methoG at the MCC for gate and globe MOVS. P.

Wahld did not have a . prob 1_em with this. P. Wohld_ wanted to clarify that to meet the ASME

) Ccde, the stop watch method either at the MCC for mate and alobe val cs and at the control room for the other valves is all that is recuired. But to ensure that we identify valve

, d?aradation, we should have an alternative test. such as the one we described earlier. This een be done quarterly or some other reasonable frequency TED would establish.
