all DOE Elements involved with the operation of accelerators.
b. Contractors. Except for the exclusions in Paragraph 3c, the Contractor
Requirements Document (CRD), Attachment 1, sets forth requirements that must
be applied to all contractors awarded contracts and subcontracts for performing
accelerator operations for DOE at DOE-owned or -leased facilities. Contractor
compliance with the CRD must be required to the extent set forth in a contract.
Contractors must be directed to continue to comply with the requirements of the

site and off-site impacts to workers, the public, and the environment from the
facility for both normal operations and credible accidents.
Section 2
(2) The SAD must contain sufficient descriptive information and analytical results
pertaining to specific hazards and risks identified during the safety analysis
process to provide an understanding of risks presented by the proposed
operations.
(3) The SAD must provide appropriate documentation and detailed description of
engineered controls (e.g., interlocks and physical barriers) and administrative
measures (e.g., training) taken to eliminate, control, or mitigate hazards from
operation.
(4) The SAD must include or reference a description of facility function, location, and
management organization in addition to details of major facility components and
their operation.

5-26-99
Vertical line denotes change.
(5) The SAD must be prepared as a single document addressing the hazards of
the entire accelerator facility or as separate SADs prepared for discrete
modules of the facility such as injectors, targets, experiments, experimental
halls, or any other type modules.
(6) The SAD must be maintained current and consistent with the administrative
control measures and physical configuration of the facility and major safety
equipment.
b. Accelerator Safety Envelope.
(1) A documented Accelerator Safety Envelope (ASE) must define the set of
physical and administrative bounding conditions for safe operations based on
the safety analysis documented in the SAD.
(2) Any activity violating the ASE must be terminated immediately; the activity
must not recommence before DOE has been notified.
c. Unreviewed Safety Issue. Activities that involve an Unreviewed Safety Issue must
not be performed if significant safety consequences could result from either an
accident or a malfunction of equipment important to safety for which a safety
analysis has not been performed. Activities involving an identified Unreviewed
Safety Issue must not commence before DOE has provided written approval.
d. Accelerator Readiness Reviews. Accelerator Readiness Reviews (ARRs) must be
performed prior to approval for commissioning and routine operation and as
directed by the cognizant Secretarial Officer or a Field Element manager.
e. Training and Qualification.
(1) Training and qualification requirements must be established for each
individual at an accelerator facility whose activities could affect safety and
health conditions or whose safety and health could be affected by facility
activities. Training and qualification must be documented and kept current.
(2) Only appropriately trained and qualified personnel, or trainees under the
direct supervision of trained and qualified personnel, are permitted to
perform tasks that may affect safety and health.
(3) All personnel assigned to or using the accelerator facility (including
emergency response personnel) must be trained in the safety and health
practices and emergency plans consistent with their involvement and the
hazards present.

(1) Written procedures that provide clear instructions for safely conducting activities
must be maintained current and consistent with management systems and the
configuration of the facility and equipment and must be approved by facility senior
line manager in the contractor’s organization who are actively involved in the day-
to-day operation of the facility.
(2) Written procedures must include a description of the tasks to be performed,
appropriate safety and health precautions and controls, and where applicable,
requirements for verifying initial conditions, operating conditions to be
maintained, and data to be recorded.
Section 3
(3) At a minimum, the contractor must prepare procedures for operation startup,
normal operation, emergency conditions, conduct of maintenance, approval and
conduct of experiments, review and approval of facility modifications,
management of safety-related changes, and control of facility access.

periodically assess and document the condition of the facility, equipment, and
engineered safety systems.
(2) Appropriateness and implementation of procedures, administrative controls, and
personnel training and qualifications must be periodically reviewed and
documented by the internal safety review system.
