DOE-STD-3007-2007

nuclear facilities. Chapter 3 of a DSA includes identification and analyses of hazards and hazard controls

to provide adequate protection to the public, workers, and the environment. CSEs provide detailed

information that should be reviewed when constructing DSA hazard analysis scenarios. However, while

such scenario entries in the hazard analysis may summarize CSE information, they are expected to be a

"stand-alone" product that does not incorporate CSEs into the DSA.

Section V contains provisions for the implementation of this standard and for surveillances that ensure

that CSEs are reviewed periodically. There is no requirement to reissue or revise existing CSEs that are

fully compliant with the applicable ANSI/ANS-8 Standards solely to meet the expectations of this

revision of Standard 3007.

Finally, the DOE Nuclear Criticality Safety Program (NCSP) developed a tutorial as a training aid for

developing CSEs. It may be found by going to the NCSP website at: http://ncsp.llnl.gov/

The NCS Engineer Training module on CSEs is consistent with the guidance in this standard. It includes

an example CSE that may be useful to the reader of this standard.
