Paying Attention to Partially Implemented Changes

The contractor should pay special attention to partially implemented changes. Failure to

identify and take the proper precautions for partially implemented changes can lead to the

premature closure of a modification package, operation in an unanalyzed condition,

and/or documentation that is inconsistent with the actual configuration.

Two types of partially implemented changes can occur:

staged implementation, where availability of time, money, or equipment dictates

that the modification has to be planned and implemented in a staged manner or

interrupted implementation, where the implementation could not be completed as

planned for any of a variety of reasons.

DOE O 5480.19 defines requirements for conduct of operation, including temporary

modification control. It states:

Administrative control systems should be established for installation of temporary

modifications such as electrical jumpers, lifted leads, pulled circuit boards, disabled

annunciators/alarms, mechanical jumpers/bypasses, temporary setpoint changes, installed

or blocked flanges, disabled relief or safety valves, installed or removed filters or

strainers, plugged floor drains, and temporary pipe supports. Prior to modification, these

controls should provide for communicating the installation of temporary modifications to

the design authority to allow for technical oversight and an evaluation of the impact on

current design activities, and approval of the design modification. These control systems

should make provisions for safety reviews, installation approval, independent verification

of correct installation and removal, documentation of the modification, update of

operating procedures and documents, training, marking of installed modifications, and

the periodic audits of outstanding modifications.

In addition, DOE O 5480.19 contains additional instructions related to control of

equipment status, lockouts and tagouts, and other areas associated with conduct of

operations applicable to partially implemented changes.

5.5.6.1 Design Analysis for Partially Implemented Changes

The change control package for a staged implementation should identify the various

stages of implementation and provide an analysis of the operation at each stage. For
