TENNESSEE VALLEY AUTHORITY SEQUOYAH NUCLEAR PLANT SYSTEM OPERATING INSTRUCTION I -SO-62-9 CVCS PURIFICATION SYSTEM Revision 41 QUALITY RELATED PREPARED BY: OLIVIA TAYLOR RESPONSIBLE ORGANIZATION: OPERATIONS APPROVED BY: W. T. LEARY EFFECTIVE DATE: 03/29/10 LEVEL OF USE: CONTINUOUS USE REVISION DESCRIPTION: Revised Section 8.3 and 8.4 to remove steps which close 1 915 due to valve operator malfunction. Also made changes to Att I for 1-62-915 configuration.(10000087)

PERFORMANCE OF THIS PROCEDURE COULD IMPACT REACTIVITY

I -S 0-62-9 SQN CVCS PURIFICATION SYSTEM Rev. 41 1

Page7of 147 3.0 PRECAUTIONS AND LIMITATIONS A. Personnel Hazards

1. Follow all radiological control procedures and precautions while performing this instruction.

2. Removing the Reactor Coolant Filter from service must be coordinated with RADOON before any valves are manipulated.

3. When the Reactor Coolant Filter is removed from service, dose rates in the area of the centrifugal charging pumps could be higher than normal.

4. Flushing a mixed bed demineralizer to Tritiated Drain Collector Tank (TDCT) may cause Airborne activity in Auxiliary Building.

5. Entry into the filter cubicles requires a confined space permit.

B. Mixed Bed Demineralizer Operation

1. The water temperature entering the mixed bed demineralizers must not exceed 145° F, to prevent resin damage.

2. Maintain flow through Mixed Bed Demineralizers within design flow rate of between 20 and 120 gpm when bed is in service, except during RCS cleanup in Modes 5 or 6. 0-GO-7 contains requirements for raising letdown flow to 180 gpm during outages.

3. Boron Concentration Changes

a. An unanticipated power change of greater than +/- 1%, OR rod motion greater than +/- 5 steps OR TAVG change greater than +/-1°F should be evaluated as a potential reactivity management event per SPP-10.4 Reactivity Management Program.

b. To avoid rapid reduction of RCS Boron concentration, either ensure mixed bed demin has been previously borated prior to placing in service, or borate slowly while placing in service.

c. Placing a previously used or borated bed in service when the RCS Boron concentration is low (EOL), may result in a decreased Tave requiring large amounts of dilution. Flush bed with RCS water before placing in service.

d. Placing a previously used or borated bed in service when the RCS Boron concentration is high (BOL) and bed was last used when Boron concentration was low (EOL), will result in an increase in Tavg and a possible increase in reactor power.

3. Online rules will be applied for a shift when any portion of the shift where the unit is defined to be online.

NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 15 of 52 3.2.1 10 Code of Federal Regulations (CFR) 26 Overtime Limits (continued)

C. Outage Requirements

1. While working on an outage unit, and without issuance of a waiver, an individuals required days off shall adhere to the requirements listed in Table 2 below (not an average):

Table 2. Required Minimum of Days Off for Outages Group 8 Hour Shift 10 Hour Shift 12 Hour Shift Days Off Days Off Days Off Maintenance 1 day off per week 1 day off per week 1 day off per week Operations, Radiation Protection, 3 days off in each 3 days off in each 3 days off in each Chemistry successive (i.e., successive (i.e., successive (i.e.,

2. Table 2 applies to the first 60 days of a unit outage; after this 60 day period expires normal online work hour limits will apply.

The 60 day period may be extended seven days on an individual basis for each 7 day block during which they worked 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months or less. Multiple 7 day extensions may be given to an individual as long as the 7 day blocks are not overlapping.

3. An operator who is on outage work-hour limitations should not provide relief to the operator at the controls or the senior operator in the control room for an operating unit, unless another operator who has been on non-outage work hours Is not immediately available and the operator has had 2 days off in the preceding 7 day period. If the operator has not had 2 days off in the preceding 7 day period and no other operator who has had 2 days off is immediately available, the operator may provide short-term relief (up to 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months ) to the operator at the controls or the senior operator in the control room for an operating unit or long-term relief (more than 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months ) under a waiver of the Minimum Days Off (MDO) requirement that is applicable to the shift schedule (i.e., 8, 10, or 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months shifts) for personnel assigned to the operating unit.

4. Contractors/vendors are responsible for tracking and reporting their hours to their supervisors between outages. The NPG is not responsible for accounting for contractor/vendor work hours prior to supporting an outage unless the contractor/vendor is coming directly from another NPG site.

5. Minimum days off may be scheduled throughout the week, or 15 day period, without restraint (i.e., does not have to be one (1) day off every five (5) days).

NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 16 of 52 3.2.1 10 Code of Federal Regulations (CFR) 26 Overtime Limits (continued)

6. A new shift cycle will be used at the completion of an outage. Post-outage transitions are in compliance if the unplanned outage schedule for the shift cycle would have provided for the required average days off.

7. If the interval between outages for a worker is less than nine (9) days, then the individual shall have a 34 hour3.935185e-4 days 0.00944 hours 5.621693e-5 weeks 1.2937e-5 months break period and shall not exceed the following limits:

a. 16 work hours in any 24-hour period,

b. 26 work hours in any 48-hour period, and

c. 72 work hours in any 7-day period.

8. The option of keeping workers on normal online work hour restrictions is still available during outages.

3.2.2 Calculating Work Hours A. Work hour limits and the associated calculation and tracking of work hours apply to the individuals who perform covered work. This calculation includes both covered and non-covered work since the latter also contributes to fatigue.

B. Work hour accounting practices may be different from record keeping for payroll purposes or gate times.

C. Work hour records should show the number of hours worked each calendar day. Work period start and stop times should be recorded and documented in a consistent manner.

D. Included In Work Hour Calculation

1. All work, both covered and non-covered work, performed by the individual for the licensee (including hours worked while working from home)

2. Non-incidental duties (i.e., incidental duties exceeding the nominal, cumulative 30 minutes) performed off-site. The time between leaving the station and the non-incidental duty are also included if that time is less than 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months in duration

3. Any break time during the work period

4. Time spent at lunch

5. Call-ins (when an individual is called in to work) are considered an addition to the normal work schedule and, therefore, shall be included. The time between leaving the station and the call-in work period are also included if that time is less than 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months in duration

6. Shift holdovers to cover for late arrivals of incoming shift members

NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 17 of 52 3.2.2 Calculating Work Hours (continued)

7. Early arrivals of individuals for licensee required meetings, training, or pre-shift briefings for special evolutions (these activities are not considered shift turnover activities)

8. Holdovers for interviews needed for event investigations E. Excluded From Work Hour Calculation

1. Either on-coming or off-going shift turnover

2. Only that portion of a break or rest period during which there is a reasonable opportunity and accommodation for restorative sleep (e.g., a nap of at least 30 minutes)

3. Incidental duties performed off-site (e.g., technical assistance by telephone from home), provided the cumulative duration of the work does not exceed a nominal 30 minutes during any single break period, may be excluded and are not considered a work period/work shift. Exceeding the nominal 30 minutes results in that time period counting as a workday.

4. Hours worked above the normal scheduled work hours for the purpose of participating in the actual conduct of an unannounced emergency preparedness exercise or drill may be excluded from the calculation of an individuals work hours. If an individual is on a day off, it is still considered a day off.

5. Paid hours during which the individual is not expected to perform work (e.g.,

vacation time, sick days, personal leave).

6. Waivers for changing to/from daylight savings time are not required 3.2.3 Work Hour Scheduling A. Work hours for covered individuals shall be scheduled with the objective of preventing impairment from fatigue due to duration, frequency, or sequencing of successive shifts.

B. Consider the following factors when establishing schedules:

1. Work hour limits defined in 10 CFR 26, Subpart I

2. Consistent start/stop times for work periods

3. Impact of backward shift rotation

4. Training requirements

5. Vacation scheduling

[NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 18 of 52 3.2.3 Work Hour Scheduling (continued)

NOTE To determine if an individual is eligible for a call-in work period use the guidelines from Steps 3.2.30 and 3.2.3D.

C. Evaluation of periodic overtime for covered individuals work hours should be performed with respect to an expected average of 54 hours6.25e-4 days 0.015 hours 8.928571e-5 weeks 2.0547e-5 months per week.

D. Hours worked should be evaluated to determine if any limit will be exceeded based on the work schedule by a backward look at the number of hours that have or will have been worked based on a time in the future (i.e., if the individual works at time T, how many hours will he/she have worked in the 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months s/48 hours!7 days preceding time T relative to 10 CFR 26 work hour limits as well as minimum days off and break requirements).

E. When entering an unplanned outage, unplanned security outage or increased threat condition, compliance with 10 CER 26 work hour limits is met if the schedule for the shift cycle would have provided the required average days off.

F. Deviations from 10 CFR 26 overtime limits may occur as the result of administrative errors or unforeseen circumstances. A PER shall be initiated, in accordance with SPP-3.1, Issue Identification and Screening Process, for each individual when this occurs.

G. An individual is considered reset from deviation, whether under a waiver or otherwise, when they meet the hours worked and break requirements and have met the minimum days off requirement in the last seven (7) day period.

H. Refer to eSOMS related guidance for use of the software to perform work hour calculating and scheduling.

3.2.4 Transitions A. Non-shift workers transitioning onto a shift (e.g., non-shift SRO standing proficiency watch) shall adhere to 10 CFR 26 overtime limits and have all work (including non-covered work performed before joining the shift) included in the calculation of their work hours. If the individual joins a shift after the start of a shift cycle, they shall meet the average days off requirement going forward and the minimum days off requirement for the shift from which they have transitioned.

B. If an individual is transitioning to a different shift schedule for a long period of time, the applicable day off requirement is found by calculating the average duration of the shifts worked and to be worked during a period not more than six (6) weeks that encompasses the schedule transition. If the average shift duration is not more than nine (9) hours, then the minimum day off requirements for 8-hour shift schedules would apply. If the average shift duration is more than 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months but not more than 11 hours1.273148e-4 days 0.00306 hours 1.818783e-5 weeks 4.1855e-6 months then the requirements for a 10-hour shift would apply, and so forth.

NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 19 of 52 3.2.4 Transitions (continued)

C. If an individual is transitioning to a temporary shift schedule, then the individuals MDOs shall be evaluated against the average shift hours.

D. When an individual works during two or more successive outages and the interval(s) between successive outages is less than nine (9) days, then the individual must have had a 34-hour break period and have not exceeded the following limits: 16 work hours in any 24-hour period, 26 work hours in any 48-hour period, and 72 work hours in any 7-day period.

3.2.5 Accounting A. Accounting practices may be different from record keeping for payroll purposes. Work periods should be rounded con.sistently. Also, it should be noted that gate or payroll times may not be an appropriate measure of 10 CFR 26 compliance since these measures may not be representative of work activities.

B. Work hour records should show the number of hours worked each calendar day. Work period start and stop times should be recorded and documented in a consistent manner. Hours worked and start/stop times are per the scheduled shift times unless a change to work times is entered and approved.

C. The cognizant supervisor will ensure any hours worked in excess of the schedule are included into eSOMS prior to the beginning of the individuals next shift.

D. The periods of 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months , and 7 days are considered rolling time periods.

Rolling means the period is not re-zeroed or reset following a day off or after obtaining authorization to exceed 10 CFR 26 overtime limits. The 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months , 48 hours5.555556e-4 days 0.0133 hours 7.936508e-5 weeks 1.8264e-5 months , and 7 days periods do not restart after a day off; the period continues to roll.

3.2.6 Waivers A. Waivers shall be granted on an individual basis and only to address circumstances that could not have been reasonably controlled. Waivers may be granted if both of the following requirements are met:

1. The Site Vice President determines that the waiver is necessary to mitigate or prevent a condition adverse to safety, or to maintain site security, and approves the waiver.

The cognizant supervisor shall perform a face-to-face fatigue assessment on the individual and determine if there is reasonable assurance that the individual will be able to safely and competently perform assigned duties during the additional work period for which the waiver will be granted. The supervisor performing the assessment shall be trained in accordance with the requirements of 10 CFR 26.29 and 10 CFR 26.203(c) (ATIS 00074642) and shall be qualified to oversee the work (or related work) to be performed by the individual.

Fatigue assessments prior to the individual performing any work under the waiver shall be performed no more than four hours before the work activity.

NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 20 of 52 3.2.6 Waivers (continued)

B. If there is no supervisor on-site who is qualified to oversee the work, the assessment may be performed by another trained supervisor who is qualified to oversee the work being performed.

C. The documented basis for a waiver must include the circumstances that necessitate the waiver, a statement of the scope of work, a time period for which the waiver is approved, and the bases for the approval of the waiver.

D. Examples of instances that would most likely meet the threshold for a waiver:

1. Risk significant SSC fails placing the unit in a shutdown LCD and maintenance crews must be held over or called in for repairs.

2. At the onset of an unplanned outage an individual, who is part of the minimum shift complement, must be held over due to relief not available.

3. Severe weather that requires hold-over of personnel.

E. Cognizant supervisors must track waivers by initiating a PER. See Attachment 2 for waiver process.

3.2.7 Fatigue Assessments A. Conditions Requiring a Fatigue Assessment

1. For Cause In response to an observed condition of impaired individual alertness creating a reasonable suspicion that an individual is not fit for duty.

a. Conduct fatigue assessment in response to an observed condition of impaired individual alertness creating a reasonable suspicion that an individual is not fit to safely and competently perform their duties, except if the condition is observed during an individuals break period.

b. A fatigue assessment need only be conducted when the observed condition is reasonably believed to be due to impaired alertness with no other behaviors or physical conditions creating a reasonable suspicion of possible substance abuse.

c. The individual who observed the condition may not conduct the fatigue assessment.

2. Self-Declaration In response to an individuals self-declaration to their supervisor that they are not fit to safely and competently perform their duties for any part of a work shift because of fatigue.

NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 21 of 52 3.2.7 Fatigue Assessments (continued)

a. It is the responsibility of each individual to communicate a clear self-declaration of fatigue to their cognizant supervisor. This may be verbally initiated, when necessary, by using the statement below. A casual statement to a supervisor or fellow employee that an individual is tired is not a self-declaration. Any individual covered by the FFD program can self-declare.

By the requirements of 10 CFR 26, I believe I am too fatigued to perform the duties assigned to me and would like to make a self-declaration of fatigue.

Once an individual has made a verbal self-declaration, they must be removed, as soon as practicable, from duty and given the opportunity to complete Attachment 1,Section II. The individual must ensure their cognizant supervisor receives the form prior to the end of shift. The self-declaration is formal once an individual has submitted it to the supervisor; the cognizant supervisor completes Attachment 1, Sections III and IV.

b. Self-declarations of fatigue should be encouraged to facilitate a healthy safety conscious work environment.

c. If an individual is performing or being assessed for work under a waiver and makes a self-declaration of fatigue, the cognizant supervisor, as soon as practicable, shall stop the individual from performing any covered work and allow that individual to complete Attachment 1,Section II.

d. A self-declaration fatigue assessment shall be performed as soon as possible.

e. If the individual must continue performing the covered work until relieved, then the supervisor shall take immediate action to relieve the individual and provide oversight of the individual.

f. Following the self-declaration or relief from performing the covered work, as applicable, the cognizant supervisor:

(1) May reassign the individual to duties other than covered work, but only if the results of a fatigue assessment indicate the individual is fit to safely and competently perform those other duties.

(2) May permit or require the individual to take a break of at least 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months before the individual returns to performing any covered work and ensure the individual is provided safe transportation home.

(3) Conduct a fatigue assessment in response to an individuals self declaration to their supervisor that they are not fit to safely and competently perform their duties for any part of a work shift because of fatigue.

NPG Standard Fatigue Management and SPP-1 .5 Programs and Work Hour Limits Rev. 0008 Processes Page 22 of 52 3.2.7 Fatigue Assessments (continued)

g. If an individual disagrees with the results of a fatigue assessment, then the individual may request a second assessment by another trained FFD assessor. The individual may also pursue other management and oversight paths for resolution.

3. Post-event In response to events requiring post-event drug and alcohol testing as specified in 10 CFR 26.31(c).

a. Conduct a fatigue assessment in response to events requiring post-event drug and alcohol testing. (SPP-1.2)

b. Necessary medical treatment shall not be delayed in order to conduct a fatigue assessment.

c. The individual who conducts the fatigue assessment may not have:

(1) Performed or directed (on-site) the work activities during which the event occurred, (2) Performed, within 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months before the event occurred, a fatigue assessment of the individuals who were performing or directing (on-site) the work activities during which the event occurred, and (3) Evaluated or approved a waiver of the limits for any of the individuals who were performing or directing (on-site) the work activities during which the event occurred, if the event occurred while such individuals were performing work under that waiver.

4. Follow-up To follow up after a for cause fatigue assessment or before an individual returns to work after a self-declaration resulting in a break of less than 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months .

a. Conduct a follow-up fatigue assessment and determine the need to implement controls and conditions before permitting the individual to resume performing any duties if:

(1) A fatigue assessment was conducted for cause, or (2) After a self-declaration, the individual returned to duty following a break of less than 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months .

(3) If no break occurs, only one assessment is required.

5. Waiver As required by Section 3.2.6, Waivers.

NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008

. Processes Page 23 of 52 3.2.7 Fatigue Assessments (continued)

B. Fatigue assessments shall, at a minimum, address:

1. Acute and cumulative fatigue considering the individuals work history for at least the past 15 days. Fatigue may not be assessed solely based on the fact that an individual has not exceeded any work hour limits and has met all minimum day off requirements.

2. Potential degradations in alertness and performance due to circadian variations (particularly with respect to time of day when assessing for a waiver).

3. Potential degradations in alertness and performance to affect risk significant functions.

4. Whether any controls and conditions must be established under which the individual will be permitted to perform work.

C. Conducting a Fatigue Assessment

1. Only supervisors and FFD program personnel who are trained under 10 CFR 26.29 and 10 CFR 26.203(c) (ATIS Training Course 00074642) may conduct fatigue assessments. The fatigue assessor shall limit inquiries of the individual to information necessary to assess the required factors and review the individuals performance, if applicable.

2. Individuals shall provide complete and accurate information that may be required to address the required factors. The fatigue assessor shall limit inquiries of the individual to information necessary to assess the required factors and review the individuals performance, if applicable.

3. Fatigue assessments shall not conclude an individual is fit-for-duty solely based on the fact that the individuals work hours have not exceeded any of the work hour limits or that the individual has had the minimum breaks or minimum days off, as applicable.

4. Following a fatigue assessment, the cognizant supervisor shall determine and implement the controls and conditions, if any, which are necessary to permit the individual to resume the performance of their duties for the licensee, including the need for a break.

5. Individuals sent home in lieu or as a result of a fatigue assessment should be evaluated to determine if alternate transportation is appropriate. Personnel safety should be considered in any decision to send someone home due to fatigue.

6. Cognizant supervisors shall document the circumstances that necessitated the fatigue assessment and any controls and conditions that were implemented in Attachment 1. A copy of this record will be forwarded to and maintained by the Site Subject Matter Expert. Cognizant supervisors must track fatigue assessments by initiating a PER coded as Fatigue Rule and ensure the use of appropriate anonymity in the PER.

NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 24 of 52 3.2.7 Fatigue Assessments (continued)

7. Each site shall maintain fatigue assessment records for covered individuals for three years. These records shall include:

a. The conditions under which each fatigue assessment was conducted (i.e.,

self-declaration, for cause, post-event, follow-up).

b. Documentation of whether or not the individual was working on outage activities at the time of the self-declaration or condition resulting in the fatigue assessment.

c. The category of duties the individual was performing, if the individual was performing covered work at the time of the self-declaration or condition resulting in the fatigue assessment.

d. The management actions, if any, resulting from each fatigue assessment.

3.3 Fatigue Management A. Fatigue management requirements, with the exception of work hour controls, are part of the FFD Program requirements and apply to all individuals (i.e., NPG employees and contractors/vendors) who:

1. Have unescorted access to protected areas (even if their current location is not on-site), or

2. Are required to physically report to the Technical Support Center or an Emergency Operations Facility, in accordance with site Emergency Plans and procedures (even if their current location is not on-site or they do not have unescorted access). Except for covered individuals in this group, the work hour limits discussed in Step 3.2 are not applied to all emergency response personnel.

B. Personnel are required to be fit for duty. Getting sufficient rest is required to ensure a person is not subject to fatigue.

C. Personnel who make choices that result in less than adequate sleep to remain alert and avoid fatigue are not meeting their obligations.

3.4 Conflict Resolution NOTE If the individual was determined to be fit-for-duty and disagrees with this finding, the cognizant supervisor needs to consider the impact of the individual working under distress. The cognizant supervisor should engage their management to discuss options and trending.

A. All applicable individuals have the right to self-declare. Self-declarations of fatigue should be encouraged and respected.

. Procedure Page5of2l 1.0 PURPOSE This procedure establishes the requirements for disabling/enabling alarms, tracking disabled alarms, establishing compensatory monitoring requirements, and the use of disabled alarm identifiers on annunciator windows. This instruction also establishes the requirements for disabling of individual inputs to annunciator windows. Attachments to this instruction provide the required approvals, compensatory monitoring, instructional steps, tracking mechanism, and restoration steps for strict control of this activity.

2.0 SCOPE This procedure provides administrative instructions to control and identify the status of the control room annunciators. This instruction should not be used to circumvent the permanent design change process. It is intended to apply to alarms or alarm inputs for reasons such as the following:

to address nuisance alarm conditions.

to restore alarm functions for alarms with multiple inputs.

to support maintenance or testing activities.

3.0 INSTRUCTIONS 3.1 GENERAL REQUIREMENTS A. Before an annunciator can be disabled, the action must be reviewed to ensure that it will not result in an unsafe condition for equipment, personnel, or the public.

B. Before an alarm can be bypassed, the ability to monitor the condition the alarm is intended to indicate must be evaluated such that if the condition were to occur as the condition changes, Operations personnel will be made aware of the condition change in a timely fashion. A timely fashion is determined by the urgency of the operator response to the alarm.

C. Any Annunciator disablement requiring a IOCFR5O.59 review or a Technical Evaluation (as specified in Appendix A) shall have necessary paperwork completed before disabling the alarm.

D. Each alarm input to be disabled will be reviewed to determine its impact on Technical Specifications, TRM, ODCM, FSAR, EOls, Radiological Monitoring, and Environmental Evaluation equipment.

E. Verification is required for removal and replacement of alarm points associated with safety systems in accordance with SPP-1 0.3.

F. An alarm point may be temporarily placed in service to determine if the condition has cleared or if corrective maintenance was sufficient to correct the deficiency provided the steps for enabling are included in the work document.

NPG Standard Annunciator Disablement OPDP-4 Department Rev. 0004 Procedure Page 6 of 21 3.1 GEN ERAL REQUIREMENTS (continued)

G. Numerous alarms receive input from multiple points, any of which may cause the alarm to annunciate. If the alarm does not have reflash (i.e., the alarm contacts are Daisy Chained in the field), other alarm contacts may be masked while the one alarm contact is in. If possible, the cause of the alarm should be determined, and the individual point removed from scan, or leads disconnected in the field to restore the alarm function from other inputs.

H. Form OPDP-4-1, Disabled Alarm Checklist shall be maintained in the Disabled Annunciator Book with a copy of the 50.59 review and Technical Evaluation (if applicable).

I. The Shift Manager/Unit Supervisor shall evaluate the acceptability of and approve any compensatory monitoring required for annunciators to be disabled.

J. If an annunciator is found to be in a failed state or inoperable, the Unit Supervisor or Shift Manager should refer to the appropriate Technical Specification and/or FSAR sections to evaluate system operability.

3.2 Disabling an Alarm NOTE Appendix B, RPV Flange Leak Case Study provides Operating Experience (OE) on inappropriate alarm disablement and should be referred to prior to starting the remainder of the procedure.

Emrloyees Disablinc Alarms A. Initiate Form OPDP-4-1 for each alarm to be disabled.

B. Determine if alarm point can be disabled by Operations:

When an annunciator window/input is disabled as directed/allowed in an approved plant procedure (excluding maintenance or surveillance activities, a separate 50.59 review and Technical Evaluation are not required since the procedure has ajready been reviewed and approved. The following example would be an alarm disablement per an approved plant instruction:

A system operating instruction directs or allows an alarm disablement due to abnormal conditions which are addressed (and restored) by that instruction.

NOTE The initiation and processing of a work order does NOT constitute in-process maintenance.

Refer to Section 5.0 Definitions.

B. If an annunciator window/input is disabled in support of maintenance or surveillance activities, a 50.59 review is not required UNLESS the annunciator will remain disabled for more than 90 days. If 90 days will be exceeded, a 50.59 review shall be completed prior to exceeding 90 days. A Technical Evaluation is required prior to disablement if alarm functions will be disabled for equipment remaining in service (not removed from service/inoperable for the maintenance activity).

1. The following example would be considered necessary to support maintenance activities and requires a Technical Evaluation:

. A pump is tagged with a clearance for maintenance. Its suction pressure switch will be depressurized and disabling the associated low pressure alarm will disable the alarm function for other equipment that must remain in service.

2. The following examples would be considered necessary to support maintenance activities and do not require a Technical Evaluation provided the parameter is the only input to the alarm:

A pump is tagged with a clearance for maintenance. Its suction pressure switch will be depressurized and the associated low pressure alarm disabled.

An instrument is declared inoperable, and any required LCO action(s) are entered for calibration in accordance with an approved maintenance instruction. The alarm from this instrument is disabled.

NPG Standard Annunciator Disablement OPDP-4 Department Rev. 0004 Procedure Page 13 of 21 Appendix A (Page 2 of 2)

Technical Evaluation and 50.59 Applicability C. When an annunciator window/input must be disabled due to degraded or inoperable equipment with maintenance NOT in progress, a 50.59 review is required prior to disabling the alarm EXCEPT when covered by an approved plant procedure (item A). A Technical Evaluation is also required EXCEPT when covered by an approved plant procedure (item A) OR when the affected alarm function is only monitoring equipment which is inoperable/out-of-service and the alarm will be restored prior to declaring the affected equipment operable or returning it to service. The following excerpt from NEI 96-07 is an example of a degraded condition affecting multiple alarm inputs:

. A level transmitter for one Reactor Coolant Pump (RCP) lower oil reservoir failed while at power. The transmitter provides an alarm function, but not an automatic protective action function. The transmitter and associated alarm are described in the UFSAR as protective features for the RCPs, but no technical specification applies. Loss of the transmiffer does not result in the loss of operability for any technical specification equipment. The transmitter fails in a direction resulting in a continuous alarm in the control room. The alarm circuitry provides a common alarm for both the upper and lower oil reservoir circuits, so transmitter failure causes a hanging alarm and a masking of proper operation of the remaining functional transmitter. Precautionary measures are taken to monitor lower reservoir oil level as outlined in the alarm manual using available alternate means. An interim compensatory action is proposed to lift the leads (temporary change) from the failed transmitter to restore the alarm function for the remaining functioning transmitter. Lifting the leads is a compensatory action (temporary change) that is subject to 10 CFR 50.59. The 10 CFR 50.59 screening would be applied to the temporary change itself (lifted leads), not the degraded condition (failed transmitter) to determine its impact on other aspects of the facility described in the UFSAR. If screening determines that no other UFSAR-described SSCs would be affected by this compensatory action, the temporary change would screen out, i.e., not require a 10 CFR 50.59 evaluation.

D. If an annunciator window or input must be disabled for other reasons (e.g. due to actual plant parameters which are known/suspected to be at or exceeding the alarm setpoint), then a 50.59 review and Technical Evaluation are required prior to disabling the alarm, EXCEPT when covered by an approved plant procedure (item A).

NPG Standard Annunciator Disablement OPDP-4 Department Rev. 0004 Procedure Page 14 of 21 Appendix B (Page 1 of 1)

RPV Flange Leak Case Study On initial restart after a 22-year idle period, BEN Ui started experiencing high Drywell (D/W) temperature alarms. These were attributed to changes in the ventilation system that occurred during the idle period. The alarm setpoints were raised to clear the alarm.

The Unit also experienced an RPV Flange leakage pressure high alarm. This was attributed to water trapped between the RPV Flange 0-rings heating up. It was actually due to a leaking inner 0-ring.

The Unit continued to experience high DIW temperature alarms and again the setpoints were raised. The high temperature alarms were not correlated to a known leaking inner RPV seal 0-ring and the possibility of an outer leaking 0-ring.

The RPV seal high pressure alarm was disabled using this procedure. The person completing the evaluation believed there were no other indications that could be used to warn the operator of degrading conditions so there were no compensatory monitoring actions specified.

The leaking RPV Flange 0-rings resulted in increased DJW unidentified leakage. The station responded to increasing leakage by forming a high impact team. Although the team made four D/W entries to find the source of the leak, the key piece of information that would have helped them, the RPV Flange seal high pressure alarm, had been disabled.

The alarm disablement process should not degrade the operators (stations) ability to detect degrading plant conditions due to conditions getting worse or detecting additional failures (the RPV seal high pressure alarm did not detect the outer 0-ring failure) and there was no monitoring to look for it.

Plant personnel did not connect the high D/W temperatures to the RPV seal high pressure or the unidentified leakage because setpoints had been raised to clear alarms and an alarm was disabled without additional monitoring.

An operator who is on outage work-hour limitations should not provide relief to the operator at the controls or the senior operator in the control room for an operating unit, unless another operator who has been on non-outage work hours Is not immediately available and the operator has had 2 days off in the preceding 7 day period, If the operator has not had 2 days off in the preceding 7 day period and no other operator who has had 2 days off is immediately available, the operator may provide short-term relief (up to 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months ) to the operator at the controls or the senior operator in the control room for an operating unit or long-term relief (more than 2 hours2.314815e-5 days 5.555556e-4 hours 3.306878e-6 weeks 7.61e-7 months ) under a waiver of the Minimum Days Off (MDO) requirement that is applicable to the shift schedule (i.e., 8, 10, or 12 hour1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months shifts) for personnel assigned to the operating unit.

4. Contractors/vendors are responsible for tracking and reporting their hours to their supervisors between outages. The NPG is not responsible for accounting for contractor/vendor work hours prior to supporting an outage unless the contractor/vendor is coming directly from another NPG site.

5. Minimum days off may be scheduled throughout the week, or 15 day period, without restraint (i.e., does not have to be one (1) day off every five (5) days).

NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 16 of 52 3.2.1 10 Code of Federal Regulations (CFR) 26 Overtime Limits (continued)

6. A new shift cycle will be used at the completion of an outage. Post-outage transitions are in compliance if the unplanned outage schedule for the shift cycle would have provided for the required average days off.

7. If the interval between outages for a worker is less than nine (9) days, then the individual shall have a 34 hour3.935185e-4 days 0.00944 hours 5.621693e-5 weeks 1.2937e-5 months break period and shall not exceed the following limits:

a. 16 work hours in any 24-hour period,

b. 26 work hours in any 48-hour period, and

c. 72 work hours in any 7-day period.

8. The option of keeping workers on normal online work hour restrictions is still available during outages.

3.2.2 Calculating Work Hours A. Work hour limits and the associated calculation and tracking of work hours apply to the individuals who perform covered work. This calculation includes both covered and non-covered work since the latter also contributes to fatigue.

B. Work hour accounting practices may be different from record keeping for payroll purposes or gate times.

C. Work hour records should show the number of hours worked each calendar day. Work period start and stop times should be recorded and documented in a consistent manner.

D. Included In Work Hour Calculation

1. All work, both covered and non-covered work, performed by the individual for the licensee (including hours worked while working from home)

2. Non-incidental duties (i.e., incidental duties exceeding the nominal, cumulative 30 minutes) performed off-site. The time between leaving the station and the non-incidental duty are also included if that time is less than 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months in duration

3. Any break time during the work period

4. Time spent at lunch

5. Call-ins (when an individual is called in to work) are considered an addition to the normal work schedule and, therefore, shall be included. The time between leaving the station and the call-in work period are also included if that time is less than 10 hours1.157407e-4 days 0.00278 hours 1.653439e-5 weeks 3.805e-6 months in duration

6. Shift holdovers to cover for late arrivals of incoming shift members

NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 17 of 52 3.2.2 Calculating Work Hours (continued)

7. Early arrivals of individuals for licensee required meetings, training, or pre-shift briefings for special evolutions (these activities are not considered shift turnover activities)

8. Holdovers for interviews needed for event investigations E. Excluded From Work Hour Calculation

1. Either on-coming or off-going shift turnover

2. Only that portion of a break or rest period during which there is a reasonable opportunity and accommodation for restorative sleep (e.g., a nap of at least 30 minutes)

3. Incidental duties performed off-site (e.g., technical assistance by telephone from home), provided the cumulative duration of the work does not exceed a nominal 30 minutes during any single break period, may be excluded and are not considered a work period/work shift. Exceeding the nominal 30 minutes results in that time period counting as a workday.

4. Hours worked above the normal scheduled work hours for the purpose of participating in the actual conduct of an unannounced emergency preparedness exercise or drill may be excluded from the calculation of an individuals work hours. If an individual is on a day off, it is still considered a day off.

5. Paid hours during which the individual is not expected to perform work (e.g.,

vacation time, sick days, personal leave).

6. Waivers for changing to/from daylight savings time are not required 3.2.3 Work Hour Scheduling A. Work hours for covered individuals shall be scheduled with the objective of preventing impairment from fatigue due to duration, frequency, or sequencing of successive shifts.

B. Consider the following factors when establishing schedules:

1. Work hour limits defined in 10 CFR 26, Subpart I

2. Consistent start/stop times for work periods

3. Impact of backward shift rotation

4. Training requirements

5. Vacation scheduling

NPG Standard Fatigue Management and SPP-1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 18 of 52 3.2.3 Work Hour Scheduling (continued)

NOTE To determine if an individual is eligible for a call-in work period use the guidelines from Steps 3.2.3C and 3.2.3D.

C. Evaluation of periodic overtime for covered individuals work hours should be performed with respect to an expected average of 54 hours6.25e-4 days 0.015 hours 8.928571e-5 weeks 2.0547e-5 months per week.

D. Hours worked should be evaluated to determine if any limit will be exceeded based on the work schedule by a backward look at the number of hours that have or will have been worked based on a time in the future (i.e., if the individual works at time T, how many hours will he/she have worked in the 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months s/48 hours/7 days preceding time T relative to 10 CFR 26 work hour limits as well as minimum days off and break requirements).

E. When entering an unplanned outage, unplanned security outage or increased threat condition, compliance with 10 CFR 26 work hour limits is met if the schedule for the shift cycle would have provided the required average days off.

F. Deviations from 10 CFR 26 overtime limits may occur as the result of administrative errors or unforeseen circumstances. A PER shall be initiated, in accordance with SPP-3.1, Issue Identification and Screening Process, for each individual when this occurs.

G. An individual is considered reset from deviation, whether under a waiver or otherwise, when they meet the hours worked and break requirements and have met the minimum days off requirement in the last seven (7) day period.

H. Refer to eSOMS related guidance for use of the software to perform work hour calculating and scheduling.

3.2.4 Transitions A. Non-shift workers transitioning onto a shift (e.g., non-shift SRO standing proficiency watch) shall adhere to 10 CFR 26 overtime limits and have all work (including non-covered work performed before joining the shift) included in the calculation of their work hours. If the individual joins a shift after the start of a shift cycle, they shall meet the average days off requirement going forward and the minimum days off requirement for the shift from which they have transitioned.

B. If an individual is transitioning to a different shift schedule for a long period of time, the applicable day off requirement is found by calculating the average duration of the shifts worked and to be worked during a period not more than six (6) weeks that encompasses the schedule transition. If the average shift duration is not more than nine (9) hours, then the minimum day off requirements for 8-hour shift schedules would apply. If the average shift duration is more than 9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months but not more than 11 hours1.273148e-4 days 0.00306 hours 1.818783e-5 weeks 4.1855e-6 months then the requirements for a 10-hour shift would apply, and so forth.

NPG Standard Fatigue Management and SPP..1.5 Programs and Work Hour Limits Rev. 0008 Processes Page 19 of 52 3.2.4 Transitions (continued)

C. If an individual is transitioning to a temporary shift schedule, then the individuals MDOs shall be evaluated against the average shift hours.

D. When an individual works during two or more successive outages and the interval(s) between successive outages is less than nine (9) days, then the individual must have had a 34-hour break period and have not exceeded the following limits: 16 work hours in any 24-hour period, 26 work hours in any 48-hour period, and 72 work hours in any 7-day period.

3.2.5 Accounting A. Accounting practices may be different from record keeping for payroll purposes. Work periods should be rounded consistently. Also, it should be noted that gate or payroll times may not be an appropriate measure of 10 CFR 26 compliance since these measures may not be representative of work activities.
