Shift Manning (4.8 / ODP-2)
-
Any position (except the SM) can be unfilled for < 2 hours (emergency only)
- However, an SRO can be upgraded to SM by Ops Manager. If SM left, an on-site SRO (CRS) could become “SM” until relieved within 2 hours.
- One SM per unit

- One extra AO in Unit 1 for “Outside Area Watch”
- One STA per unit (3 total) OR two STAs on site and one ENS communicator.
-
Two ROs and three AOs shall be present within each unit at all times.
- Within the Unit: Area containing each unit bounded by PA fence and fences running north and south between the spray ponds and adjacent unit.
- The 4th AO must be in communication with the MCR and be able to return within 10 minutes.
- AOs can be reduced to 2 on a unit if support is needed on another unit during a Significant Event (SM permission)
- AO is part of the crew composition if they are on site and in direct communication with the MCR via radio or pager.
- Refuel SRO – Directly supervises all core alterations
-
One ENS Communicator per unit (3 total)
- Stationed when continuous NRC communications required (Alert or higher) or requested
- Has no other E-plan duties. Separate from the STSC Communicator.
- ENS communicator is knowledgeable of the plant (RO, SRO, STA, AO or a previously licensed).
- Usually covered by the STA from another unit (if 3 STAs are on-site)
- Two STSC Communicators for the site (2 total)

- Alarms are communicated directly to who?…
- Silencing alarms:
- Alarm Acknowledge: what do you do?…
- Flasher Reset: what do you do?…
- SM or CRS permission is required to do what?…
A
Alarm Response / Requirements:
- Alarms are communicated directly to the CRS and prompt action is taken to identify the cause. If known, report both RJ and RK.
- Treat as valid until proven otherwise.
- Silencing alarms:
- Alarm Acknowledge: scan all boards for other alarms.
- Flasher Reset: scan the affected board, at a minimum, for other alarms.
- Multiple, simultaneous alarms may be grouped under one announcement that is most appropriate to the observed condition
- MCR refers to local ARP when AOs are directed to perform local ARPs
- An ALARM (ALL) screen shall be displayed on B01, B04, or B06 during shift operation and shift turnover.
- SM or CRS permission is required to deselect the screen due to other monitoring needs for plant conditions.
6
Q
Expected Alarms:
- Communicated to who ahead of time?…
- Are alarms not pre-briefed with the CRS are considered unexpected?…
- ?
Unexpected Alarm:
- Which alarms are unexpected?…
A
Expected Alarms:
- Communicated to CRS ahead of time.
- All alarms not pre-briefed with the CRS are considered unexpected.
- If an alarm comes in that was not pre-briefed, but is related to an activity and should have been pre-briefed: validate the alarm using available indications and the ARP to ensure no further action is required. ARP is performed at the discretion of the CRS.
- Expected alarm: verify on plant computer, communicate it to the CRS, and state the reason.
- Repeat alarm announcements can be suspended with CRS permission.
- ARP use is not required for expected alarms unless equipment manipulations are required
Unexpected Alarm:
- All alarms other than expected.
- Requires continuous use for the ARP (first response of the shift)
- ARP does not have to be referenced for subsequent alarms unless manipulations are required.

A
Alarm Abnormalities/Computer Alarms:
- Communicate alarm to the CRS.
- CRS determines the appropriate response.
- RK alarm with no computer point alarms (RJ).
- RJ alarm with no associated control board alarm window (RK) or RMS alarms.
- RMS alarms promptly reported (potential AOP/EOP entry, LCO entry, and/or E-Plan Classifications)
- Fully investigate / write CR.
Fast Flash/Locked In:
- CRS authorizes any annunciator left in fast flash.
- CRS determines the appropriate duration (≤ 1 hour), monitoring requirements, and required contingency actions.
- Alarms NOT to be left in fast flash condition (alarm is required to meet the LCO requirements, only if in the mode of applicability)
- CEA Position Out-Of-Limits (4A06B) - PDIL LCO

A
Transient Alarm Management:
- Operators should announce critical alarms
- CRS updates the crew when transient alarm response is entered.
- Automatically occurs following a reactor trip or cutback.
- CRS directs the transition back to the use of normal alarm response (once the plant is stable)
Fire Protection Alarms within the Power Block:
- SM/STA immediately notified of actual “Fire” alarms to evaluate E-plan.
- Operations only operates fire protection equipment during emergent situation or to protect equipment and/or area damage.

A
Manual SESS Inputs:
- Initiated when any monitored component or system is Inoperable:
- Disabled and unable to perform the intended function by any method that is not alarmed
- Examples: filling SIT with B HPSI pump, local 3.6.3 admin controls
- Required if impairment or failure is anticipated to last longer than the current shift.
- Should be initiated at the time of the occurrence but in all cases shall be in place prior to shift turnover.
- Document initiation, removal, and reason for SESS manual inputs in the Unit Log.
- Initiate a Technical Specification Component Condition Record (TSCCR) if applicable.

Equipment Hand Switch Positioning Following Actuation (ODP-1 14.0):
- ?…
A
Automatic Actions (4.6.2):
- Validate automatic initiations and actuations occur. Ensure actions take place in response to valid initiation signals, unless such action complicates a transient or is prohibited by procedure.
-
Failure of an automatic action:
- Informs the CRS prior to performance of an action
- Manually perform the actions necessary to fulfill the function
- Report completion of the manual action to the CRS
-
Approved actions without referencing a procedure:
- Tripping the main turbine if trip setpoint exceeded
- Starting a standby pump if it fails to auto start.
- Initiating a cutback due to automatic failure.
- Tripping a MFP on loss of NNN-D15 or NNN-D16
- Starting Standby Charging Pump
- Manually actuating a reactor trip or ESFAS if setpoint exceeded and it did not occur. (Does NOT require CRS concurrence)
Equipment Hand Switch Positioning Following Actuation (ODP-1 14.0):
- Does NOT apply to equipment with override capability (PZR HTRs) OR systems with independent control systems (IA Compressors).
- Match the HS for Non-class** equipment that **auto started or tripped on bus undervoltage.
-
Class equipment: Only match HS per a procedure OR as directed by CRS
- May actuate an override OR cause equipment damage.

- ?…
Manual Override of Automatic Systems (4.7.14):
- CRS concurrence required prior to what?…
- ?…
A
Prompt and Prudent Mitigating Actions (4.7.5):
- CRS concurrence
- Mitigates complications due to equipment malfunctions or degrading plant conditions
- Action is allowed (from memory) to place plant in stable condition.
- Only if inaction would result in:
- unwarranted/preventable shutdown LCO entry
- imminent equipment damage
- plant transient (reactor trip, turbine trip, cutback, loss of letdown, reactivity excursion, etc.)
- personnel injury
- Confirm actions with the procedure as soon as possible.
Manual Override of Automatic Systems (4.7.14):
- CRS concurrence required prior to transfer (auto or manual)
- Discuss during PJB for normal procedures (expected duration / contingency actions)
-
If auto function fails and manual control must be taken, immediately notify all MCR of controller status
- As time permits, discuss manual control, potential transients, post trip requirements, etc.
- If the operator believes a transient can be controlled by taking manual control, then the operator should do so immediately and inform the other MCR personnel of the action.
- CRS shall state his acceptance or direct alternate actions_._
