Conducting the OSR

DOE-STD-3015-2004

e. Plan briefings, observations, and resources as required to support the OSR.

f. Establish an agenda and schedule for the OSR.

The chair documents and distributes the results of this meeting including a statement

regarding the OSR scope, objectives, and schedule to the meeting participants.

Preparation for, and conduct of, an OSR is the primary responsibility of the NESSG

personnel, and TAs participating in an OSR, for the timeframe required to support the

OSR. Conflicts must be resolved in favor of OSR duties from the date the supporting

documentation is available until conclusion of the OSR.

8.3.4 CONDUCTING THE OSR

Five key elements central to the conduct of an OSR are briefings, NEO observations,

deliberations, report generation, and feedback. One significant difference between a

NESS and an OSR is that the OSR participants will observe actual NEOs rather than

a simulation using trainer units or other mock-ups. During the conduct of the OSR,

NESSG personnel evaluate the adequacy of controls to meet the three DOE NES

Standards, and other NES criteria, as evidenced in the performance of the NEO, the

written procedures, equipment design, and facilities.

An OSR must reach one of the following conclusions:

1. The NEO continues to meet the three DOE NES Standards (i.e., no pre-start

findings have been identified).

2. The NEO does not meet the three DOE NES Standards and must be suspended

(i.e., pre-start findings have been identified). Actions must be taken to address

specific NES concerns before resuming operations.

OSR briefings should be informative in nature rather than an oral defense typical of

NESS briefings. NESSG personnel may request briefings at planning meetings. The

purpose is to ensure a common understanding of the NEO being evaluated and
