Bio For Transition Surveillance and Maintanance of a Nuclear Facility

DOE-STD-3011-2002

maintenance are the primary activities being conducted at the facility. These activities are

necessary for satisfactory containment of hazardous materials and protection of workers, the

public, and the environment. Surveillance and maintenance activities include providing

periodic inspections and maintenance of structures, systems, and equipment necessary for the

satisfactory containment of contamination and for protection of workers, the public, and the

environment. Maintenance of the facility in a stable and known condition includes actions to

prevent the alteration in chemical makeup (e.g., chemical changes in material in storage tanks

leading to the creation of explosive mixtures), physical state, and/or configuration of a

hazardous substance or radioactive material. It also includes actions taken with regard to

physical SSCs (e.g., roofs, ventilation).

A DOE nuclear facility scheduled for transition surveillance and maintenance should

generally have some type of existing safety basis documentation, which covers the present

activities. This can range from very limited safety basis documentation to a DOE-approved

DSA. The BIO for transition surveillance and maintenance of a nuclear facility should make

maximum use of pertinent existing safety basis documentation for the facility. However, the

SAR (or DSA) that existed for the normal operational mission of the facility is not

appropriate for transition surveillance and maintenance because the safety concerns will be

different.

The BIO for transition surveillance and maintenance of a nuclear facility should include

consideration of (1) hazards associated with the facility that exist because of the presence of

hazardous materials (e.g. storage of radioactive material); (2) hazards associated with the

conduct of surveillance and maintenance activities; (3) hazards associated with the alteration

in chemical makeup, physical state, and/or configuration of a hazardous substance or

radioactive material or the degradation of the physical state of the facility and its equipment

over time and; (4) natural phenomena hazards and their impact on the remaining life of the

facility. Particular attention should be paid to the potential long period of time that the

facility may remain in this mode of operation.

While it is true that DOE desires to expedite the ultimate disposition of excess facilities,

limitations of available resources can lead to extended periods of transitional surveillance and

maintenance, sometimes without deactivation having been accomplished. The issues of

potential alteration of chemical makeup, physical state, and or configuration of a hazardous

substance or radioactive material, or the degradation of the physical state of the facility and

its equipment over time, including safety SSCs, should be given special attention when this

may be the case.

DOE G 430.1-2, Implementation Guide for Surveillance and Maintenance during Facility

Transition and Disposition, provides guidance for the development of a Surveillance and

Maintenance Plan. The development of this Plan and the development of the safety basis for

the facility during transition surveillance and maintenance should be coordinated activities.

The format of DOE-STD-3009, chapters 2 through 6, should be used to organize the

information to the following extent (i.e., it is not expected that the full formatting down to the

lowest subsection descriptions in DOE-STD-3009 must be used).
