What is the scope of 10 CFR 830 Subpart B?
This Subpart establishes safety basis requirements for Hazard Category 1, 2, and 3 DOE nuclear facilities.
830.201 Performance of work. Subpart B - Safety Basis Requirements
How should a contractor perform work?
A contractor must perform work in accordance with the DOE-approved safety basis for a Hazard Category 1, 2, or 3 DOE nuclear facility and, in particular, with the hazard controls that ensure adequate protection of workers, the public, and the environment.
830.203 Unreviewed safety question process.
What is the USQ process?
(a) The contractor responsible for a Hazard Category 1, 2, or 3 DOE nuclear facility must establish, implement, and take actions consistent with a DOE-approved USQ procedure that meets the requirements of this section.
(b) The contractor responsible for a new Hazard Category 1, 2, or 3 DOE nuclear facility must submit for DOE approval a procedure for its USQ process on a schedule that allows DOE approval in a safety evaluation report issued pursuant to § 830. 207(a) of this part.
(c) The contractor responsible for a Hazard Category 1, 2, or 3 DOE nuclear facility must implement the DOE-approved USQ procedure in situations
(d) A contractor responsible for a Hazard Category 1, 2, or 3 DOE nuclear facility must obtain DOE approval prior to taking any action determined to involve a USQ.
(e) The contractor responsible for a Hazard Category 1, 2, or 3 DOE nuclear facility must annually provide to DOE a summary of the USQ determinations performed since the prior submittal.
What situations must a contractor improvement the DOE-approved USQ procedure?
Where there is a:
(1) Temporary or permanent change in the facility as described in the existing documented safety analysis;
(2) Temporary or permanent change in the procedures as described in the existing documented safety analysis;
(3) Test or experiment not described in the existing documented safety analysis; or
(4) Potential inadequacy of the documented safety analysis because the analysis potentially may not be bounding or may be otherwise inadequate.
What must a contractor do if it discovers or is made aware of the of a potential inadequacy of the documented safety analysis?
(1) Take action, as appropriate, to place or maintain the facility in a safe condition until an evaluation of the safety of the situation is completed;
(2) Notify DOE of the situation;
(3) Perform a USQ determination and notify DOE promptly of the results; and
(4) Submit the evaluation of the safety of the situation to DOE prior to removing any operational restrictions initiated to meet paragraph (f)(1) of this section.
830.204 Documented safety analysis.
What must a contractor responsible for a Hazard Category 1, 2, or 3 DOE nuclear facility do in preparing the DSA?
The contractor responsible for a Hazard Category 1, 2, or 3 DOE nuclear facility must obtain approval from DOE for the methodology used to prepare the documented safety analysis for the facility unless the contractor uses a methodology set forth in Table 1 of Appendix A to this part.
830.204 Documented safety analysis.
What are the six (6) things the DSA should include?
(1) Describe the facility (including the design of safety structures, systems and components) and the work to be performed;
(2) Provide a systematic identification of both natural and man-made hazards associated with the facility;
(3) Evaluate normal, abnormal, and accident conditions, including consideration of natural and man-made external events, identification of energy sources or processes that might contribute to the generation or uncontrolled release of radioactive and other hazardous materials, and consideration of the need for analysis of accidents which may be beyond the design basis of the facility;
(4) Derive the hazard controls necessary to ensure adequate protection of workers, the public, and the environment, demonstrate the adequacy of these controls to eliminate, limit, or mitigate identified hazards, and define the process for maintaining the hazard controls current at all times and controlling their use;
(5) Define the characteristics of the safety management programs necessary to ensure the safe operation of the facility, including (where applicable) quality assurance, procedures, maintenance, personnel training, conduct of operations, emergency preparedness, fire protection, waste management, and radiation protection; and
(6) With respect to a nonreactor nuclear facility with fissionable material in a form and amount sufficient to pose a potential for criticality, define a criticality safety program.
830.204 Documented safety analysis.
Should should the critical safety program include?
(i) Ensures that operations with fissionable material remain subcritical under all normal and credible abnormal conditions;
(ii) Identifies applicable nuclear criticality safety standards; and
(iii) Describes how the program meets applicable nuclear criticality safety standards.
830.205 Technical safety requirements.
In regards to technical safety requirements, what must a contractor responsible for a Hazard Category 1,2 or 3 DOE nuclear facility do? (first item of 3 items)
(1) Develop technical safety requirements that are derived from the documented safety analysis;
(2) Prior to use, obtain DOE approval of technical safety requirements and any change to technical safety requirements; and
(3) Notify DOE of any violation of a technical safety requirement.
830.205 Technical safety requirements.
In regards to technical safety requirements, what else must a contractor responsible for a Hazard Category 1,2 or 3 DOE nuclear facility do? (2&3 of 3 items)
(b) A contractor may take emergency actions that depart from an approved technical safety requirement when no actions consistent with the technical safety requirement are immediately apparent, and when these actions are needed to protect workers, the public or the environment from imminent and significant harm. Such actions must be approved by a certified operator for a reactor or by a person in authority as designated in the technical safety requirements for nonreactor nuclear facilities. The contractor must report the emergency actions to DOE as soon as practicable.
(c) A contractor for an environmental restoration activity may follow the provisions of 29 CFR 1910.120 or 29 CFR 1926.65 to develop the appropriate hazard controls (rather than the provisions for technical safety requirements in paragraph (a) of this section)
830.205 Technical safety requirements.
What further definition of activities quality the contractor to follow environmental restoration activity may follow the provisions of 29 CFR 1910.120 or 29 CFR 1926.65?
Provided the activity involves either:
(1) Work not done within a permanent structure, or
(2) The decommissioning of a facility with only low-level residual fixed radioactivity.
830.206 Preliminary documented safety analysis.
What should the contractor responsible for the design and construction of the new facility or major modification do?
Prior to construction of a new Hazard Category 1, 2, or 3 DOE nuclear facility or a major modification to an existing Hazard Category 1, 2, or 3 DOE nuclear facility, the contractor responsible for the design and construction of the new facility or major modification must:
(a) Prepare a preliminary documented safety analysis for the facility, and
(b) Obtain DOE approval
830.206 Preliminary documented safety analysis.
What does DOE approve?
(1) The nuclear safety design criteria to be used in preparing the preliminary documented safety analysis unless the contractor uses the design criteria in DOE Order 420.1, Facility Safety, or successor document; and
(2) The preliminary documented safety analysis before the contractor can procure materials or components or begin construction; provided that DOE may authorize the contractor to perform limited procurement and construction activities without approval of a preliminary documented safety analysis if DOE determines that the activities are not detrimental to public health and safety and are in the best interests of DOE.
830.207 DOE approval of safety basis.
With respect to a new Hazard Category 1, 2, or 3 DOE nuclear facility or a major modification to an existing Hazard Category 1, 2, or 3 DOE nuclear facility, a contractor may not begin operation of a the facility or modification until?
(a) With respect to a new Hazard Category 1, 2, or 3 DOE nuclear facility or a major modification to an existing Hazard Category 1, 2, or 3 DOE nuclear facility, a contractor may not begin operation of the facility or modification prior to the issuance of a safety evaluation report in which DOE approves the safety basis for the facility or modification.
(b) Pending issuance of a safety evaluation report in which DOE approves an updated or amended safety basis for an existing Hazard Category 1, 2, or 3 DOE nuclear facility, the contractor responsible for the facility must continue to perform work in accordance with the DOE-approved safety basis for the facility and maintain the existing safety basis consistent with the requirements of this Subpart.
