It is human nature to question the reliability of any historical data and information. Maintaining a complex set of information over several decades and then expecting the custodian to actually use it when making critical decisions should not be underestimated.

A well-constructed and robust system for managing the technical and contextual content of the information is thereby essential if reliability, confidence and trust are to be ensured.

Whilst the wastes vary, the management objective is common – safe storage and, ultimately, disposal. The information produced over the decades to support this objective must be properly and responsibly managed. Failure to do so may compromise the industry’s long term capability to achieve safe storage and disposal. Enabling knowledge creation and transfer from one generation of workers to the next is essential.
