documents are required. This dual role places fundamental limits on the

ability of DOE to completely segregate the processes of preparation and

review of these documents. For example, the FEM has responsibility for

both the operation of the facility and the review and approval of the DSA

and TSRs. However, in order to be as objective as possible in the review

process, most of the reviewers of the DSA and TSRs should not be

responsible for the operation of the facility, including the preparation of the

DSA and TSRs. It is not expected that these reviews will be conducted

completely separate from the preparation. This standard encourages

interface between the two processes to develop familiarity with the facility's

safety basis, to respond to requests from the preparer for early

identification and resolution of potential issues, and to discern the scope of

subsequent review and the extent of approval documentation required.

DOE strives for an effective, streamlined review and approval process for

DSAs and TSRs while still achieving an acceptable level of safety

assurance. This Standard advocates proper planning for a review and

encourages an integrated review process where all parties with vested

interest in a facility safety basis coordinate throughout the review and

approval.

DOE manages review issues requiring resolution for approval in that

reviewers establish and document the safety significance of issues prior to

submittal for possible resolution. Guidance is provided to focus facility

contractor's resolution of issues on those issues determined to be

necessary for adequately establishing and documenting the facility safety

basis.

This Standard provides guidelines for reviewing the DSA through

assessment of the major subject areas of a safety analysis as defined by

the following DSA approval bases:

Base information;

Hazard and accident analyses;

Safety structures, systems, and components (SSCs);

Derivation of technical safety requirements; and

Safety management program characteristics

This Standard also provides guidelines for reviewing the TSRs. There is

only one approval basis for a TSR document and that is the TSR

provisions themselves. Determining the adequacy of the TSRs generally

entails a disciplined analysis and tracing of commitments to hazard

controls in a DSA through appropriate provisions that implement these

controls in a TSR document.

The Safety Evaluation Report (SER) is primarily a management document that

provides the approval authority the basis for the extent and detail of the review

of the DSA and TSRs and the basis for and any conditions of approval. This

Standard endorses the concept that the contents of a SER are concise

summary statements and that little benefit is gained from the wholesale

recapturing of elements already contained in a DOE -owned DSA or TSRs or

from reproducing original analysis that, if deemed critical, is performed as part

of the review process.
