Expirations and Extensions

DOE-STD-3015-2004

NESSG findings impact ongoing operations, the Site Office or NA-15 should provide

direction to operations personnel deemed appropriate based on the information in the

findings. The range of options include suspending the affected operations, implementing

corrective or compensatory measures, and allowing operations to continue unchanged

pending further evaluation or NA-12 decision.

Responsible Site Offices and NA-15 must define a process for closure of approved

NESSG findings that:

Ensures closure of approved NESSG findings categorized as "pre-start" prior to

initiation or continuation of NEOs;

Establishes plans, resources, responsibilities, and timing for closure of approved

NESSG findings categorized as "post-start"; and

Provides for tracking approved NESSG findings to closure.

NA-122 must generate quarterly status reports on the corrective actions planned and

taken for approved NESSG findings. Distribution is to include NA-12, NA-121, the

responsible Site Offices, NA-15, NNSA-SC/NESD, design agencies, and M&O

contractors.

The current status of all open NESSG findings must be addressed in subsequent NESSs,

OSRs, and, if relevant, NCEs.
