NMP-OS-007-001 Conduct of Operations Standards and Expectations

Critical Parameter

ANY that SS determines heightened awareness:

Abnormal control (Manual vs. Auto) or outside band

When CP established, SS and watch stander will agree on:

Monitoring method

Limit/Band

Action if exceeded

Frequency of monitoring*
“For CPs in the control room the parameter will be consistently monitored by a Plant Operator”

CP must be notified to SM as soon as practical

IF greater than a shift: Narrative Log entry or alternative tracking and discuss during turnover

Key Parameter

“Power, Pressure, Level” and Temperature

Core, Pressurizer, Steam Generators

Vogtle 3&4 Succession of Responsibility

Plant Manager

Operations Director

Shift Manager

Shift Supervisor

Vogtle 3&4 Pre-Approved Two-Handed Manipulations

DAS Control Panel (MCR)

Resets for the following DAS actuations:

 PRHR

 CMT

 Containment Isolation

 Containment Cooling (PCS)

Remote Shutdown Room (RSR)

Over/Under Switches for Onerous Actuations:

 ADS Stages 1-3

 ADS Stage 4

 IRWST Injection

 Containment Recirculation

 RNS Isolation

*SS may allow exceptions directed/required by design

Alarm Response Normal vs. Transient Conditions

Normal:

ALL alarm actuation should be communicated, grouping IS allowable when appropriate

Transient:

It is understood not all will be communicated, the qualified watch stander will assess and communicate NEW/UNKNOWN issues commensurate with the significance

Expected Alarm Requirements

Actions required PRIOR to actuation:

Preview ARP(s)

As appropriate Flag alarms

Communicate pending alarm

*When alarm occurs:

Tested: Ensure compensator actions are performed

Subsequent alarms for same activity are NOT required to be verbalized

If no actions were required, ARP/SOP reference NOT required

Nuisance Alarms

Criteria:

Re-flash often due to actual condition/indication failure

Seal-in/re-flash longer frequency with false plant condition

SS has determination to silence nuisance alarms, these DO REQUIRE a CR

Crew Brief Nuanced Information

A PAUSE in the brief is taken to respond to alarms/controls however it IS permissible to delay ARP actions until completion of brief

Orders are NOT given during Briefs therefore repeat-backs will NOT be used during briefs

OATC “Distraction” Allowances

Specific Allowances and Prohibited Activities

Logs, Maximo, D2, Tagging, Plant Cameras, Grid monitoring, Plant Computer

Specific Prohibited Activities:

Any Email

Internet usage INCLUDING CBTs (No training allowed)

Specific System requiring additional Oversight/Actions

Any RNS action shall go through SS

IF time to 200F(SFP) <24hrs SS must maintain direct oversight

Fleet-wide Skill of the Craft Items

Quick Connect Fittings

Alarm acknowledgement

Firefighting Equipment

Recorders

Temporary Equipment

Holding Turbine ramps using Ovation

Testing panel alarms

Cabinet light switches

Navigating HMIs

Abnormal Configuration Time Requirements

Immediate Hazard: Implement Tagging Procedure

<2 Shifts, No more than 1 turnover: Narrative Logs with SS permission

Anything Greater: (in order of preference) Generatre WO, TCC, Design change

Thermal Power Average exceed time limit/requirement

If you exceed the average for 2 hours, take immediate action to fix
