NOTICE OF ADOPTED AMENDMENTS
B) Alternatively, for each pressure vessel that can be inspected only
during refueling outages, the owner may develop an inspection
plan for the remaining life of the pressure vessel. The plan shall
provide that an inspection of each pressure vessel will occur prior
to the completion of every 2 consecutive refueling outages, but in
no case more than 5 years after the last inspection of the pressure
vessel. The owner may include in the plan contingency options for
conducting inspections during unplanned or extended refueling
outages, provided the required frequency of inspection is met. The
bases for the inspection plan may include, but is not necessarily
limited to, alternative examinations and tests planned and
performed, past performance of this and similar pressure vessels,
status of the pressure vessel in the plant's maintenance program,
the environment and contents of the pressure vessel, vessel use,
service condition (operating or not) of the pressure vessel relative
to operation of the plant, corrosive environment where the pressure
vessel is installed, risks, methods of inspection, ALARA (as
defined in 32 Ill. Adm. Code 310) considerations, trade-offs and
relevant engineering data. This plan shall be submitted to the
AgencyDepartment for approval.
4) Pressure vessels not subject to internal corrosion shall be inspected in
accordance with subsection (a)(4)(A) or (B) of this Section as applicable,
unless the AgencyDepartment approves an alternative under subsection
(a)(4)(C) of this Section:
A) Vessels containing incompressible fluids (e.g., water) shall be
inspected externally every 5 years.
B) Vessels containing compressible fluids (e.g., air steam), or a
combination of compressible and incompressible fluids, shall be
inspected externally every 3 years.
C) Alternatively, the owner may develop an inspection plan for the
vessel for its remaining life based upon refueling outages. This
plan shall be submitted to the AgencyDepartment for approval.
The basis for such an inspection plan may include alternative
examinations and tests planned and performed, past performance
of the pressure vessel and similar pressure vessels, status of the
