Answer 23

``` "AD-ADM-30-1209 Acceptable Preconditioning (of SSCs): Preconditioning based on the equipment manufacturer’s recommendations or on industry-wide operating experience to enhance equipment and personnel safety but not to influence the outcome of the test. Preconditioning for purposes of personnel protection or equipment preservation should outweigh the benefits gained by testing only in the as-found condition. This preconditioning must be evaluated and documented in advance of the surveillance. ``` Preventive maintenance should not be deliberately scheduled just prior to a surveillance interval test for purposes of assuring testing success. Repetitive testing to achieve acceptable test results without identifying the cause or correction of any problem in a previous test is NOT acceptable to establish or confirm operability and may constitute “preconditioning”. Tech Spec required periodic venting of equipment not routinely scheduled prior to the surveillance testing is acceptable. Pump venting or draining directly prior to surveillance is acceptable provided a Technical Evaluation is performed to establish the amount of gas vented would not adversely affect the pump operation. Except where there is a need to protect personnel or prevent equipment damage, preventive maintenance should not be performed before TS surveillance testing. Do not routinely schedule TS surveillance interval tests after maintenance activities so the surveillance test can also serve as the post maintenance test. It is acceptable preconditioning to run the prelube oil pumps prior to EDG starts. Unacceptable Preconditioning activities should not to be routinely scheduled within 25% of the time period prior to the associated surveillance interval due date."

NMP-OS-007 SS is responsible for the safe and efficient operation of the assigned unit • SS approval must be obtained prior to conducting any evolutions or testing that affect core reactivity • Approve the removal of equipment and systems from service for maintenance, testing or operational activities • SS Walks down the control boards and control room displays at turnover and at least once during the shift (preferably with the UO/OATC) to verify component position and system parameters. This walk-down should be recorded in the unit control log.(verified current version 17.0) • Gives permission to start Infrequently Performed Tests and Evolutions in accordance with NMP-AD-006. • Reviews AND approves the Unit Control Log for the assigned unit. The off-going SS will make a log entry stating that they have reviewed the log and that the log clearly and accurately reflects the status of the unit and the activities that occurred during the previous shift. (NMP-OS-007-008 3.3.4)

Answer 36

"NMP-OS-001 | SS approval must be obtained prior to conducting any evolutions or testing that affect core reactivity

Answer 37

"NMP-OS-007 Shift Manager is the senior management representative on shift and has primary responsibility for the safe operation of the facility. • Reports to the MCR when notified by the SS of: o Unplanned LCO entry <72hours o AOP/EOP entry o Any time decision is being made in knowledge base instead of rule base in response to a failure or transient • The Shift Manager maintains awareness by walking down control boards and displays on a frequency no less than once per shift. This walk-down should be recorded in the unit control log. • Declares emergencies per the plant Emergency Plan. The ED has the following non-delegable duties: o The decision to declare, escalate, or terminate emergency classifications. o The decision to notify offsite emergency response agencies. o The decision to recommend protective actions to offsite authorities. o The decision to request federal assistance. o Authorization for plant personnel to exceed 10CFR20 radiation exposure limits. o Authorization for use of potassium iodide (KI) tablets during a declared emergency. o The decision to dismiss nonessential personnel from the site at an ALERT or higher emergency classification. • Responsible for the oversight of planned and unplanned risk changes • Gives permission to start Infrequently Performed Tests and Evolutions in accordance with NMP-AD-006.

Answer 38

NMP-OS-007-001 Critical Parameter - Any parameter that the Shift Supervisor has determined will merit heightened awareness and will require a specific response from the crew or plant systems at a certain parameter value such as: • parameters not under the normal control of automatic systems • parameters not being controlled in the expected band by automatic systems • parameters not being maintained in the expected band due to plant transient or degraded equipment

Answer 39

"NMP-OS-007 OATC • Prevent challenging the automatic safety systems by taking action to manually initiate ESF actuations if the established critical parameter limits are exceeded and automatic actuation setpoints are threatened. • Ensure the reactor is shut down when o Safety of the reactor is in jeopardy, or o Operating parameters exceed any of the reactor protection system trip set points and automatic reactor trip does not occur, or o Personnel or equipment safety require it, or o Unusual circumstances warrant it. • Walks down the applicable portions of the control boards and control room displays at turnover and at intervals throughout the shift (mid-shift, and after system manipulations are recommended) to monitor component position and system parameters, these walkdowns include the following panels: a.

Answer 41

NMP-OS-007-001 * All alarms treated as valid until proven otherwise * When performed planned activities, operators anticipate alarms caused by that activity and will preview the ARP for those alarms, for any required response. * Cleared alarms are not required to be communicated * Normally all MCR alarms should be communicated during non transient conditions. (May group as single communication)

Answer 42

NMP-OS-007-001 During transient conditions alarms may be used to help establish priorities and it is understood that all ARPs are consulted immediately. o If alarm is indicative of NEW or unknown issue, the alarm should be communicated commensurate with the significance of the issue Un-expected alarm response is as follows (inclusive of MCR or Local alarm panels): o Silence and/or acknowledge the alarm, IF applicable. o Communicate the alarm to the appropriate supervisor/watch-stander/area. o The responding operator references and implements the alarm response procedure as applicable. o WHEN multiple alarms are received simultaneously, the responding operator silences and/or acknowledges the alarms. IF the cause is understood (diagnosed), the responding operator announces the cause of the alarms. ARP usage is prioritized.

Answer 43

NMP-OS-007-001 Expected Alarms response is as follows: • PRIOR to alarm actuation operators: 1. PREVIEW all associated ARPs and other procedures (e.g. SOPs). 2. As appropriate, FLAG alarms in advance which are anticipated to occur multiple times or at relatively high frequency during pre-planned evolutions. 3. COMMUNICATE the pending alarm to the appropriate station/area personnel •WHEN the expected alarm is actuated, the operator will: 1. Ensure compensatory actions are performed per the appropriate ARP or other procedure (e.g. an SOP). 2. If there are no compensatory actions required, then the ARP is not required to be referenced again after the alarm is actuated (it was referenced prior to actuation). 3. Ensure the appropriate station/area personnel received the alarm as expected. Per 31GO-OPS-014-0, Expected Annunciator Flags (EAFs) are limited in duration to the time remaining on the shift during which they were placed on the expected annunciator(s) OR for the duration of a Unit or System Outage at the discretion of Operations Supervisory personnel.

Answer 44

NMP-OS-007-001 o Re-flash (become active, clear, and reoccur) often due to an actual plant condition or indication failure or Seal-in (remain active) or re-flash at a longer frequency due to alarm system failure where the actual plant condition does not exist. o After the initial alarm response, the Alarm Response Procedures are to be referenced once per shift for any nuisance alarm. Compensatory actions may be required as determined by the Shift Supervisor o Nuisance alarms may be silenced, left flashing, and flagged to assist the operators in alarm management

Answer 45

NMP-OS-007-001 • Used during abnormal or emergency situations to ensure control room team members have a shared understanding of the events in progress. May be used in non-emergency conditions as well. • Used for quick dissemination of plant status changes and priorities. • A pause in the briefing is taken to respond to alarms or manipulate controls, however it is permissible to silence and not implement ARP actions until completion of the brief during a transient. • Orders and directives are not given during Crew Briefs…therefore no repeat backs are used during Crew Briefs

Answer 46

NMP-OS-007-003 Night Orders – Operations related information or orders issued by an Operations Manager/Shift Manager or designee to provide instructions to be carried out during backshifts, weekends, holidays, etc. Night Orders MUST NOT deviate from or change the intent of existing plant operating procedures nor do they deviate from other plant design or regulatory documents. * Night Orders are valid for 72 hours. (< 6 whole 12hr shifts) * Only ONE active night order at a time. * SS and SM shall review night orders to ensure they are carried out.

Answer 47

NMP-OS-007-003 Standing Orders – Temporary instructions issued to plant operating personnel. They address subjects NOT covered by existing plant operating procedures. Standing Orders MUST NOT deviate from, or change the intent of existing plant operating procedures, nor do they deviate from plant design or regulatory documents. * A standing order log will be maintained to track Standing Orders issued throughout the year * Standing Orders are maintained electronically, and a paper copy may be maintained in MCR • Standing Orders containing directions to manipulate the plant shall only include directions to perform actions bounded by current approved procedures. o If there is a conflict between a standing order and published plant procedure, the plant procedure will prevail in all cases. o Standing orders may direct early actions or initiate additional monitoring of plant equipment. o Standing Orders are approved by an Operations Manager or Shift Manager Standing Orders are reviewed monthly and any that have been in effect for greater than 6 months shall be evaluated for conversion to a procedure.

Answer 48

NMP-OS-007-008 The logs required to be reviewed are those generated since the last shift worked OR the last 24 hours, whichever is the least. Narrative Logs Contents All pertinent data, alarms, actions taken, plant response, and indications are recorded in the appropriate operator log(s) to allow reconstruction of plant operations and events When directing other departments to perform required actions, such as technical specifications, operability determinations, or other actions needed At the end of each shift, the logs should be reviewed and approved by the applicable SS

Answer 49

NMP-OS-007-013 The minimum shift crew composition shall be in accordance with 10 CFR 50.54. Shift crew composition may be less than the minimum requirement for a period of time not to exceed 2 hours in order to accommodate unexpected absence of on duty shift crew members provided immediate action is taken to restore the shift crew composition to within the minimum requirements. This is not by position, this is crew composition as a whole. Example: 0100 - RO leaves sick (below min staffing time starts) 0145 - SRO gets called away from the plant (still below min staffing) 0200 - Replacement RO arrives on site (still below min staffing) 0315 - Replacement SRO arrives on site (staffing meet) Total time min staffing not met was from the initial RO leaving until the SRO arrives. 2 hours 15 min. This would be a violation of min staffing.

Answer 50

NMP-OS-007-008 The SM, SS, and Control Room Operators (OATC is responsible) must review entries prior to taking the shift. The logs required to be reviewed are those generated since the last shift worked OR the last 24 hours, whichever is the least.

Answer 51

NMP-OS-007-013 Normal shift scheduling shall be a minimum of 5 SROs The FBL and STA function cannot be combined When there are only 4 SROs on a shift the ED and STA functions can be combined.

Answer 60

31GO-OPS-014-0 Annunciators/recorder points deactivated/bypassed per another controlling document (i.e., other procedures, DCRs, LDCRs, and DCPs), will only be tracked per 31GO-OPS-014-0. Any required Applicability Determinations (AD) and 10CFR50.59 Screening / Evaluations / reviews will have been performed by the other process. If the other process is to be in place greater than three months for a required annunciator, then the associated AD and 10CFR50.59 screening will be attached to the APC sheet Any APC sheet for a pulled annunciator card or bypassed point that has been active for greater than three months (90 days) or will be active greater than three months prior to the next periodic review, will be sent to Engineering Support Supervision to have an AD and 10CFR50.59 performed for those APC sheets. The SS shall assign required Compensatory Action as per the requirements of this procedure. The SM will review and approve the Compensatory Actions. The SS shall ensure Compensatory Action(s) is(are) performed at the frequency assigned on the APC Sheet, OPS-1468 Whenever an APC Log entry has been made and an APC Sheet written, THEN INSTALL an APC blank YELLOW magnetic tile beside the annunciator number label under the Annunciator window AND/OR a TM Tag on the associated recorder or plant component, if any. The TM Tag is to give the APC Sheet number and otherwise identify it as associated with an APC Sheet. Later, at step 38, if it is a deactivated annunciator the YELLOW magnetic blank tile will be replaced with a YELLOW magnetic “P” tile beside the Annunciator number label under the Annunciator window. The YELLOW “P” tile will signify that the annunciator has been “pulled”. Also, for APC sheets initiated for annunciators, place a label in the top right hand corner of the ARP with the given APC Sheet number (e.g. 1-05-025). If the condition is a distraction to the operating crew or it is masking a problem, the SM and SS can determine if it is necessary to deactivate/bypass the annunciator without PRB approval. This starts a 14 day clock to determine if PRB/Plant Manager approval is needed on safety related equipment. APC Logbook reviews: 1. Review EACH SHIFT to ensure compliance with Comp Actions and to ensure all entries are still required. 2. Review MONTHLY to ensure compliance with this procedure 3. Review MONTLY to ensure that APC sheets older than TWO MONTHS have a CR generated requesting an Applicability Determination and 50.59 for recommendations for permanent resolution 4. Review MONTLY to determine if any APCs older than 3 months do not have a 50.59 screening 5. Review MONTLY to determine if an APC is older than 6 months. IF so, report to Operations Supervision and Reg Affairs
