Decommissioning Planning ‘Top 10’ Lessons Learned and Recommendations – Part 2

One of the preliminary activities that need to be performed to enable detailed planning is characterization. Characterization includes both ‘desktop’ characterization (level 1) – reviewing of existing and historical facility/site documentation and process knowledge, and field/facility characterization (level 2) – condition assessments, surveys and materials sampling from the structure, systems and surrounding lands.

Decommissioning Planning ‘Top 10’ Lessons Learned and Recommendations (Part 1)

This 3-part series will explore a list of the ‘Top 10’ lessons learned including the typical situation, importance, impacts(s), different perspectives (contractor, owner, and stakeholder), along with recommendations for each of the ‘Top 10’ lessons learned in decommissioning planning. After all, planning is the earliest and best opportunity to positively influence scope definition, safety, cost, and schedule.

Knowledge Management From Design, Operation Throughout the Decommissioning Phases

Given the long timescales of active decommissioning projects (many decades), the preservation of information and its transfer to future generations is a fundamental element of this industry. But adding on the long time periods given to the siting, planning, construction and operation of a nuclear facility before shutdown (when most records relevant to future decommissioning are generated) the overall time span encompassing knowledge management for decommissioning purposes easily exceeds 100 years

From Preliminary to Final Planning for Decommissioning: Anything Wrong?

The key principle of planning for decommissioning should be continuity (a form of sustainability). Experience shows that a significant gap in planning will inevitably result in unnecessary delays (e.g. between final shutdown and the start of active decommissioning) and ultimately, extra costs.

Early & Detailed Decommissioning Project Planning Charts the Course for Success

As a facility nears the end of its useful and productive life, options for the facility’s lifecycle are evaluated. If it is no longer to be used or upgraded then it may be sold, or in most cases, deactivation and decommissioning begin. Planning is what ultimately sets the trajectory of a project directly towards safe and successful completion or down a tumultuous road of risks, changes, and challenges.
