FACILEX® ATOMIC

Bypass & Impairment Control Software for Nuclear Quality Assurance

Control temporary bypasses, impairments and degraded conditions through a governed process that evaluates risk, establishes compensatory measures and maintains authorization throughout the period of reduced protection.

Maintain visibility of affected equipment and functions from initial identification through implementation, monitoring, restoration and verified closure.

Reduced protection must never become an unmanaged condition.

Nuclear facilities rely on layers of equipment, controls, barriers, alarms and protective functions. Maintenance, testing, modification or equipment degradation can temporarily remove or reduce the availability of those protections.

The immediate technical condition may be understood, but the management challenge is broader: determining the significance of the impairment, identifying affected functions, establishing compensatory measures and ensuring the condition remains authorized for as long as it exists.

Temporary conditions are particularly vulnerable to becoming normalized. Without active monitoring, defined restoration criteria and clear accountability, a short-term bypass or impairment can remain in place longer than intended.

?
Bypass & Impairment Control must answer:
  • What equipment, barrier or function is unavailable or degraded?
  • What safety, quality or operational capability is affected?
  • What risk is introduced while the condition exists?
  • What compensatory measures are required?
  • Who authorized the condition and for how long?
  • Has normal capability been restored and independently verified?
!

Degraded protection becomes visible

Maintain a current view of active bypasses, impairments and temporarily unavailable functions.

◆

Risk is evaluated before acceptance

Determine the significance of the condition and whether additional controls are required before authorization.

✓

Compensatory measures are controlled

Define required temporary controls and keep them connected to the condition that made them necessary.

●

Authorization is explicit

Document who approved the condition, applicable restrictions and the period for which the authorization remains valid.

◷

Temporary conditions stay temporary

Track duration, review dates and restoration commitments so temporary impairments do not become permanent by default.

↻

Restoration is verified

Confirm that the affected capability and associated temporary controls have been properly restored before closure.

A configurable lifecycle maintains control from identification of the bypass or impairment through risk assessment, compensatory measures, authorization, active monitoring and verified restoration.

1
Initiate
Identify the bypass, impairment, degraded condition or unavailable function.
2
Assess
Evaluate affected functions, significance, duration and associated risk.
3
Compensate
Define temporary measures required to maintain acceptable protection.
4
Authorize
Obtain required technical and management approvals before proceeding.
5
Implement
Place the approved condition and compensatory measures into effect.
6
Monitor
Track status, duration, reviews, restrictions and restoration commitments.
7
Restore & Close
Restore normal capability, remove temporary measures and verify closure.
▤

Configurable Impairment Types

Define bypass, impairment and degraded-condition categories appropriate to your facility and program structure.

◆

Risk & Significance Screening

Configure evaluation criteria based on affected equipment, functions, consequences and duration.

✓

Compensatory Measures

Define, assign and track temporary controls required while normal protection is unavailable.

●

Approval & Authorization

Route conditions through appropriate technical, operational and management authorization based on significance.

◷

Duration & Periodic Review

Establish expiration dates, recurring reviews and escalation requirements for extended temporary conditions.

↻

Restoration Verification

Require confirmation that normal capability has been restored and temporary measures removed before final closure.

Maintain control whenever credited capability is reduced.

Temporary conditions affect more than equipment status.

FACILEX® ATOMIC connects bypasses and impairments with the credited functions, configuration changes, actions and corrective processes needed to maintain control until normal capability is restored.

◆
Credited Controls & Safety Functions Identify the protection or credited capability affected by the condition.
↔
Change Control Manage temporary modifications and changes affecting plant configuration.
!
Corrective Action Program Degraded or recurring conditions can initiate formal corrective action.
→
Action Item Management Compensatory and restoration actions remain assigned and accountable.

One application. Part of one connected management system.

FACILEX® Bypass & Impairment Control is one of 21 configurable applications within FACILEX® ATOMIC. Impairments can remain connected to affected safety functions, temporary configuration changes, compensatory measures, corrective actions and restoration commitments throughout their lifecycle.

Bring us your current process.

We can map your current bypass and impairment categories, risk evaluations, compensatory measures, authorization requirements, periodic reviews and restoration controls to a configured FACILEX® ATOMIC process.
