. e Work Process Pmeram OPGP03-ZA-0090 Rev.10 Page 2 of 38 l l 1.0 Puroone. Scone and Objectives i 1.1 Purpose l His procedure describes the process for evaluating, planning, scheduling and , implementing work activities to support the safe and reliable operation of the i plant. It provides the whanism for plant material problems or deficiencies l identified in accordance with OPGP03-ZX-0002, Condition Reporting Process, to be evaluated and dispositioned. 1.2 Scope ; 1.2.1 The Work Process Program encompasses the activities of all organizations related to performing work on plant systems, components and structures including corrective maintenance, preventive maintenance, surveillance inspections, special tests and modifications. l The process extends from the identification of a work requirement or ' deficiency through planning, scheduling, and implementation, to final l closure. The process elements are shown in Addendum 6. ; 1.2.2 This procedure applies to work activities (including modifications) performed on permanent plant components, systems and structures, ; including work in support areas or buildings that may impact plant j cperations. 1.2.3 The Work Process Program utilizes a two-tiered approach to correcting equipment deficiencies. The two methods are Work Orders and Rover / Minor maintenance. His tiered approach to maintenance applies the appropriate level of requirements and resources to perform work / resolve equipment deficiencies increasing the overall efficiency of the Work Process Program. All deficiencies identified on Condition Reports are evaluated to determine the most appropriate method to perform the work / resolve the deficiency. Deficiencies that do not require Work Orders are resolved using the Rover / Minor maintenance program (see Addendum ,
- 3) and are assigned directly to maintenance for !
implementation. Deficiencies that require Work Orders, are planned, l scheduled, and implemented using the Work Process l Program. i
. e Work Process Program OPGP03-ZA-0090 Rev.10 Page 3 of 38 s 1.2.4 The Condition Report (CR) is the document used to identify conditions which require maintenance work to correct, or to request the Maintenance Department or Certified Contractors to perform specific work. A Work Order (WO) is generated from the CR, and the work is performed using the WO as the work authorization document. Work authorizing documents include Work Orders, Preventive Maintenance . Tasks and Surveillances. When no administrative controls are required, work MAY be performed without a work authorizing document. 1.2.5 Work Authorization documents are not required for:
- Work on non-plant systems or systems excluded from configuration management listed in reference 5.8.
- Inspection or non-destructive examination for information only where no Work Start notification or maintenance support is required. I
- Minor housekeeping, cleanliness, and adminstrative items where no degradation of plant components and structures is involved. Items in this category MAY be identified and tracked by a punchlist. :
- Facilities Management activities.
1.2.6 When a component has been removed from service, it is not required that its configuration be kept consistent with the approved design i configuration. Intentional actions (ie., Work at Risk) are permitted which cause the actual configuratian of the out-of-service component to deviate from the approved design configuration by documenting in accordance with OPGP03-ZM-0021, provided that, prior to returning the component to service, or declaring the component OPERABLE, the inconsistency is resolved, by taking one of the following actions: 1.2.6.1 The configuration of the component is restored to be consistent with the approved design configuration. 1 1.2.6.2 An engineering evaluation is performed and documented providing the basis for allowing the component to be returned to service with the deviation still existing. 1.2.63 The approved design configuration is revised to be l consistent with the actual configuration of the component. l l

Rev.10 ; Page 4 of 38 l l 1.2.7 When deviations have been intentionally made as described above with l the expectation that the inconsistency will be resolved, such deviations are undertaken as " Work at Risk" (not approved by Engineering ). 1.2.8 *the work process uses the Corrective Action Program (CAP) and Work Management System (WMS) computer databases to develop, process and track the formal records and information needed to support the planning and scheduling process. To facilitate the Work Fim CRs SHAIL be initiated for work activities except as noted in 1.2.5. A single CR can cause the generation of one or more work orders. 1.2.9 Work Packages written prior to the effective date of this revision MAY be worked to completion without revision (Speakout 12266). 13 Objectives 13.1 To support safe and reliable plant operation. l 13.2 To maintain an integrated schedule of approved plant maintenance and > modification work activities, including preventative maintenance and surveillance activities. 133 To manage support activities to meet the implementation schedule 13.4 To allow the activities in the Control Room to focus on plant 3 operations by requiring work management functions to be performed i by the Operations Work Control Group. 2.0 Definitions ' 4 2.1 BLANKET WORK PACKAGE: A Work Package which is maintained in a

1 4.0 Procedure i 4.1 Condition Identification is the first phase of the Work Process Program. A condition Aeport is used to idendfy conditions that affect plant components, systems and structures. 4.1.1 The individual discovering the problem SHOULD:
- Examine the component and the adjacent structures to determine if a deficiency tag aheady exists and a CR has been initiated. IF a deficiency tag exists THEN no further action is required.
l
Work Process Program OPGP03-ZA-0090 Rev.10 Page 11 of 38
- IF a deficiency tag is not evident, THEN hang a Tag in a conspicuous place on or near the affected equipment.
IF the environment in which the equipment is located could affect the legibility of the tag or entry is prohibited by ALARA THEN hang the tag near the affected equipment or, outside the door. Tags SHOULD not be hung in the Reactor Containment Building.
- Initiate a condition report including the deficiency tag number in the (DEPT #) block of the CR form.
- IF the CR identifies support work, not a material deficiency, THEN the supervisor SHOULD submit the CR directly to Planning or applicable organization for processing (ie.,
manpower request to MSSD). Deficiency tags SHOULD NOT be hung to identify support work. 4.1.2 IF it is known or suspected that the condition affects OPERABILITY or SAFETY, THEN the individual discovering the problem SHALL immediately notify the Shift Supervisor. 4.1.3 'Ihe OWCG SRO/on duty Shift Supervisor SHALL immediately evaluate the CR and determine if it is an Emergency, Priority I or Priority 2 condition. Addendum 2 defines the priorities for the Work Management Process.
- IF the reported condition is evaluated as not being an Emergency, Priority 1 or Priority 2, THEN the Shift Supervisor SHAIL initiate any actions deemed mary and provide the appropriate priority for the CR.
4.1.4 IF the problem is evaluated as an Emergency. THEN the Shift Superv;sor SHAIL immediately:
- Initiate actions to mitigate safety concerns and to maintain safe operating conditions in accordance with established pro.edures.
- Notify the appropriate personnel (Engineering, Maintenance, etc.) of the condition and direct the immediate implementation of corrective actions.
- Make appropriate management notifications.
, 2 l
Work Process Prorrarn OPGP03-ZA-0090 l Rev.10 Page 12 of 38 4.1.5 IF the problem is evaluated as a Priority 1 or Priority 2 condition, e THEN the OWCG/on duty SRO SHAllinform me applicable Maintenance / Planning Supervisor of the equipment status and any special requirements that need to be followed. Work MAY commence in accordance with 0PMP01-ZA-0041, Troubleshoot and Rework Process, provided that:
- An action plan has been developed in accordance with ,
Addendum 4. l l
- A Work Package, if required, is prepared as soon as possible and the work accomplished is fully documented in, and reconciled with, the approved Work Package prior to returning the system, equipment or component to service / OPERABLE, as required.
4.2 Work Order Evaluation is the second phase of the Work Control Program. The OWCG/on duty SRO evaluates the Condition Report for deficient or degraded material conditions, technical validity, completeness and scheduling in accordance with Addendum 1. 4.2.1 The OWCG SHOULD screen, vslidate, prioritize and disposition CRs which identify material deficiencies within two working days of receipt. 4.2.2 'Ihe OWCG/on duty SRO SHOULD review and evaluate the reported condition to determine if plant OPERABILITY OR SAFETY are affected (LER l-88-010; SPR 921589). IF the deficiency affects the ability of the component to perform its intended function and the component is Tech Spec / Safety Related, and the component is to remain operable /in-service, THEN the OWCGlon duty SRO SHALL contact Engineering for an OPERABILITY review. For l non-Tech Spec /non-Safety Related components, an Operability review is not required (IR 92-04, LER l-92-003, LER l-93416). 4.2.3 The OWCG Planner SHOULD review the CR after initial screening and check the existing CRs on the equipment with the same tag /TPNS number to determine if the reported problem duplicates a previously reported condition.

- IF the new CR duplicates or can be combined with an i existing CR, THEN the Planner SHOULD add the new CR :
problem description and Date/ Time to the niming CR, ] notify planning, remove the deficiency tag, void and retum the new CR to the Originator with the disposition. j 4
- IF the new CR does not duplicate a previously reported condition, THEN the Planner SHOULD assign the j appropriate Work Type Code to the CR (Addendum 1). i
. IF a Preventive Maintenance (PM) task can be utilized, THEN the Planner coordinates scheduling the PM, voids the CR pending completion of the PM and enters PM and WAN ;
numbers in CR database. The PM planner adds a step to the PM to remove the deficiency tag. 4.2.4 The OWCG Maintenance Supervisor evaluates the need to perform a ' field walkdown of identified maintenance problems. During walkdown, the OWCG Maintenance Supervisor SHALL: ,
- Verify the Equipment / Component 'IPNS Number is !
appropriate for the described condition.
- IF it is determined that the problem has been corrected or no l longer exists, THEN remove the deficiency tag, void CR, enterjustification in data base, and return the CR to the originator with the disposition. ;
- Determine if troubleshooting in accordance with ,
OPMP01-ZA-0041. Troubleshoot and Rework Process, is required. Determine if maintenance can be implemented via the Rover , process as described in Addendum 3. I 1 , Provide a manhour estimate for the anticipated corrective action and identify the support requirements such as additional craft, the need for scaffolding and insulation . removal and other information that may be of assistance in , planning and scheduling the necessary corrective action. 4

Approves and routes CRs categorized as Rover Maintenance directly to Maintenance for implementation. Routes applicable CRs to the Chem Ops Supervisor or Operational Authority for action as applicable. Routes security discrepancies directly to the Security ) Supervisor for action. l Submits valid CRs to planning and scheduling. l l 43 Work Activity Scheduling is the third phase of the Work Precess Program. { Work Control-Scheduling is responsible for developing the various schedules used in the work management process as described in the Schedular's Guide. l 43.1 *Ihe Integrated Schedule is used to schedule on-line work activities including Corrective Maintenance, Preventive Maintenance, Surveillance Testing, and support tasks. This Schedule is based on a 12 Week Schedule Cycle which specifies when a system, sub-system or component MAY be taken out of service for maintenance or special activities (e.g., special testing requested by Engineering). 43.2 Resources SHOULD be scheduled and aligned to fully support Unit I and Unit 2 activities cencurrently (i.e., staggering of Unit I-and Unit 2 LCO work weeks, scheduling of specialty crews, etc.).
._ __ .-- _ ~_ _ _ ___
i Work Process Prorram OPGP03-ZA-0090 Rev.10 i Page 15 of 38 ; 433 Schedule dates for work activities are developed considering the following:
- Recurring, planned work activities (surveillance, EQ j program items, preventative maintenance items, and !
non-technical specification surveillance), SHOULD be scheduled for implementation in the appropriate on-line week based on assigned periodicities.
- Non-recurring work activities (corrective maintenance, modifications, post maintenace tests, etc.) SHOULD be added to the appropriate on-line week based on assigned l priorities, nesources, work scope and other information available to the scheduler.
t
- Related work activities SHOULD be grouped, tied together !
and concurrently scheduled on a component or system basis , to the maximum extent feasible. "Ihe Scheduler has the l authority to adjust the due dates for Preventive Maintenance ; items forward or backward in order to align related work l items so that the number of times equipment is taken out of l service for maintenance is minimized. IF the schedule for a j preventive maintenance item exceeds the allowable periodicity window, THEN a PM deferral SHOULD be processed in accordance with OPGP03-ZM-0002. I The work scope is finalized 3 weeks prior to Work Week (N) with the following exceptions:
- Priority 1 or 2 work.

- High priority / Task Ready work activities that require a unit outage or present a High Risk when at-power SHOULD be includd in forced outage work lists that can be implemented on short notice.
- Schedules SHOULD be resource loaded to the maximum extent feasible. Schedule changes based on resource limitations SHOULD include management review and approval at a level commensurate with the change involved.
- The status of planning activities to prepare for work implementation SHOULD be monitored on a continuous basis. Items that will not be " Task Ready" for i:nplementation 3 weeks prior to their scheduled date SHOULD be rescheduled to the next earliest opportunity in the 12 week cycle.
43.4 The Daily Schedule SHOULD be reviewed by OWCG, Operations Shift Supervisor, Chemops, Health Physics, Maintenance, Engineering, NPMM, Security and Work Control and SHOULD be approved by the Operations Manager and the Maintenance Manager. 4.4 Work Activity Planning is the fourth phase of the Work Control Program. Work Control Planning is responsible for developing or assisting in the preparation the Work Instructions needed to perform required work as described in the Planner's Guide. 4A.1 The Planner writes work instructions in sufficient detail such that qualified individuals can perform the activity safely and correctly. The Planner MAY take into account " Skill of the Craft" and write the ; instructions such that they do not describe step by step actions that the craft are trained on. IF the activity requires step by step instmetions, i THEN the instructions SHOULD be definitive enough to ensure that ) the required results are achieved (LER l-90-01). 4A.2 Troubleshooting work instructions are in accordance with OPMP01-ZA-0041, Troubleshoot and Remk Process.

EMERGENCY Emergency maintenance actions required to be parformed immediately to prevent or I mitigate the consequences of an accident, prevent the release of radioactive material to i the environment or to protect human life and/or property. Emergency maintenance is l performed at the discretion of the Shift Supervisor / Emergency Director and MAY start f without an approved work package. Emergency Maintenance SHOULD only be used during Emergency Plan events (SPR 930125). PRIORITY 1 Actions required to restore a system or function to OPERABLE status to decrease the ! risk of radiation exposure, eliminate a personnel safety hazard, return the plant to full : power operation, or satisfy a Tech Spec Limiting Condition for Operation (LCO) action ! statement. The work SHOULD continue until completed or until the circumstances . requiring the priority action no longer applies. ! PRIORITY 2 Actions required to mitigate or resolve equipment or component problems which restrict the desired level of plant operation. Priority 2 SHOULD be used only for important i activities that must override the normal work schedule. j PRIORITY 3 . t Actions assigned and coordinated on a routine basis. Priority 3 SHALL be assigned to I corrective work that supports plant operations. Priority 3 work MAY be further governed by a scheduling milestone. , I PRIORITY 4 l Activities whicli do not impact plant operation or prevent accomplishment of program events or milestanes (e.g., rework of non-essential or non-plant equipment, painting, inspections, etc.).

Tasks of this nature typically do not require detailed work instructions. This i process utilizes the skill / certification of the individuals assigned, in conjunction with specific criteria, to determine when maintenance MAY be implemented via a Minor Maintenance or ; OPMP01-ZA-0041 Work Package (SPR 933531). i' Maintenance implemented via the Rover / Minor Maintenance Process is not required to be scheduled. Rover / Minor maintenance work is used to increase process efficiency by allowing qualified / certified technicians to implement the work directly. Rover / Minor mamtenance expedites the work process and ensures that work is available (ie., discretionary / fill in) should ! the scheduled activities not be performed as planned. ; New Condition Reports are evaluated by the OWCG staff to determine their applicability to the Rover / Minor Maintenance process. If the item can be worked as Minor Maintenance as defined in 2.7, the CR itself can be used to document the work performed including parts used. The controlling document for a OPMP01-ZA-0041 Work Package is the CR. Rover Work Packages MAY be used to perform maintenance activities within the following limitations:
- The task SHALL be within the skill / certification level of the individual assigned technician (s).

Dear Joe:
This letter is to inform you of a safety concern related to operation of the referenced crane (s). an analysis revealed On a crane of similar design to yours, significant overstress on bolted connection points of the trolley main hoist components. These overstressed conditions can result in Failure et the connection points could metal fatigue and failure. It cause a dropped load and components falling from the trolley. is very likely that your crane has the same condition. Serious accidents of this type are likely to result in personal injury or death to persons working in the area of the crane and cause significant property damage. corporation, has no direct Whiting Corporation, a Delaware responsibility for the design of equipment sold inWe 1983 are,or earlier however, by Whiting Corporation, an Illinois corporation. obligated to infor accordance with 10 CFR 21. Until the time that analysis and any necessary repairs can be made, we recommend that you discontinue use of the main hoist on the referenced crane (s) to avoid the risk of a failure as previousiv describeq. a Delaware corporation, is willing to assist Whiting Corporation,in repair of these trolleys by providing engineering, repair pa e ;L J =tri:2, 'M fiald cervice supervision at a reasonable coct.

References:
- 1) ST HS HS-28048, OPERABILITY REVIEW POLAR CRANE, Dated 3/4/94
- 2) PCF 157308A The previously issued operability review for the polar crane (Reference 1) allowed the use of the main hoist for 20 tons.
In evaluating the polar crane's capacity to accommodate the reactor head lift, Whiting has recommended that some bolts be changed out on a gear box on the main hoist. PCF 157308A was issued on March 9,1994 to change out the bolts in Unit 2 as recommended ' by Whiting. Upon completion of the bolt change out per the referenced PCF, DED recommends that the main hoist on the Unit 2 polar crane be considered operable for up to 310 ton lifts based on recommendation from Whiting. Lifting for additionalloading is not recommended at this time. DED will be working with Whiting to obtain the full rated capacity. DED will also be working with the System Engineering Department, the Maintenance Department and Whiting to evaluate the configuration on the Unit 1 polar crane. Both these actions to obtain the full load rating and Unit 1 evaluation will be accomplished via Corrective Action (s) to SPR 940567. Should you have any questions, contact myself or R. L Engen at extension 7162 or 7337 respectively. RLE/hg

Reactor Building Polar Cranes (Units 1 & 2) S/N 11256 &13257
- 500/15 Ton capacity Built on Whiting Regn. 68918-30 (1976)
Trolley bolted connections related to a 10 CFR Part 21 notification. Main Hoist Unit Replacement Bolts N
Dear Mr. Engen:
As requested, attached are a set of marked drawings (U-77587 & U75473) and copies of the pages in Whiting's Bill of Materials (BOM) (Regn. 68919, page 13 of 126, and Reqn. page 13 of 126) which identifies the Main Hoist Unit support bolts that were in question. , HL&P's letter to Whiting (dated 3/8/94) states that an inspection on crans S/N 11256 (unit 2) discovered that at each of the four corners of the main hoist unit (gear box), one of the two bolts is marked as an A325 bolt and the other is not marked. This is contrary to what is specified in Whiting's BoM, which specifies all eight bolta' to be A325 (see attached BOM). Therefore, based on this informa' tion and the results of an engineering review, it'is recommended that for the scheduled lift of 310 Tons on 3/10/94, the two hoist unit support bolts in the l corner identified as #1' on the attached marke.1 drawing U-77587, be replaced with A325 bolts (3/4" diameter 2-1/2 or 2-3/4" long) on crane S/N 11256. Since these bolts are in tolerance holes, the replacement bolts must be tolerance bolts (see attachment L-2695-
- 1) . When installing them, the bolte should be torqued to 200 to 230 foot-pounds. The bolts in the other three corners need not be replaced at this time, but they should be checked for tightness (200 to 230 foot-pounds cf torque for A325 bolts and 130 to 150 foot-pounds of torque for the unmarked bolts). In the future, the remaining unmarked bolts will need to be changed before using the main hoist for loads greater than 310 Tons.
l
SENT BV: xER0x Telecocier 70. 3- 9-94 : 7:13AM ; 708i.05032* CCITT G3:# 3 ! i i ( Also, before using the main hoist on crane s/N 11257 (unit 1) an inspection of the sheave nest bolts, bearing support bolts and the main hoist unit bolts (all previously identified) will need to be performed and the proper corrective action taken before using it to lift a load. This inspection and the expected corrective action ! should be similar to the action taken on crane S/N 11256. ! l l Sincerely, We ~ William A Horvath, P.E.

"9 =^ m m Hwston Lighting & Power Coi..p:ny , OFTICE MEMORANDUM March 10, 1994 To Unit I and Unit 2 Shift Supervisors FILE NO. M13.04 ST-HS-HS-028119 from S. E. Thomas subject REPORTABILITY REVIEW POLAR CRANE - SPR 94-0567
References:
- 1) SPR 940567 Operability Review; ST-HS-HS-28048 Dated March 4, 1994 and ST-HS-HS-28111 dated March 9,1994
- 2) ST-HS-WG-00002; Letter to Whiting Documenting the Unit 2 Polar Crane Inspecdon.Results
- 3) OPGP03-ZA-0069 - Heavy Loads Promdure Station Problem Report 940567 was written on 3/3/94 to document a 10CFR part 21 repon written by Whiting Corp. on the polar crane. Whiting's report to STP stated; "On a crane of similar design to yours, an analysis revealed significant overstress on bolted connection points of the trolley main hoist components.
These overstressed conditions can result in metal fatigue and failure. Failure at the connection points could cause a dropped load and components falling from the trolley. It is very likely that your crane has the same condition." Whiting later clarified the areas of concern on the cranes supplied to STP as being: connection of the output shaft of the main hoist gear box to the bearing pedestal (or bearing pedestal bolts), connection of the main hoist gear box, upper sheave nest girder connections, and bearing cap studs. Based on inspection of the Unit 2 polar crane (Reference 2), Whiting has evaluated the stresses on the polar crane for the specific configuration at STP. Whiting's evaluation shows that for loads applied during constmetion, some of the connections may have been overstressed above the allowable stresses. However, none of the stresses exceeded the yield strength for the connections / bolts. Whiting has also determined that none of the connections were overstressed for the loads applied since the plant has been in operation. The maximum load which occurs during plant operation is 310 tons (Reference 3, Addendum 1). Accordingly, there is no concem with metal fatigue or loads applied during plant operatio'n. The Unit I polar crane has one connection on the bearing pedestal which is different than Unit 2. This connection may be overstressed during the plant operation lifts but these stresses would not exceed yield. This connection is not considered a problem since the polar crane has been tested during construction for loads significantly higher than the operational loads and the connection does not show any visible signs of distress or loose bolts. I
i ST-HS-HS-028119 Therefore, this condition has been evaluated against, but not reportable, under the requirements of 10CFR50.73 (aX2Xii, y, & vi) in that there is no evidence to demonstrate that this condition is outside of the design basis of the plant. ; If you have any questions regarding this reportability review, please contact R. M. Attar or R. Engen at site extension 8155 or 7337 respectively. 1 AL- - 3/loAq.
