Current through Register Vol. 48, No. 38, September 20, 2024
a) For all non-ISI
boilers and pressure vessels, the Agency shall determine the acceptability of
the alternative standards in accordance with this Section.
b) The Agency shall automatically accept
alternative standards that have been accepted by the NRC and referenced in the
nuclear facility's Updated or Final Safety Analysis Report, technical
specifications or other licensing documents.
c) For boilers and pressure vessels, other
than those covered by subsection (b), installed subsequent to February 7, 1994
to be constructed to alternative standards other than the ASME Code standards
referenced in Section
505.40,
the owner may request the Agency to issue a permit for the installation of a
boiler or pressure vessel not constructed in accordance with the applicable
ASME Code.
1) The owner shall submit the
documentation described in this Section to the Agency and obtain a special
installation permit.
2) The owner
shall specify the reasons why the boiler or pressure vessel cannot be
constructed in accordance with ASME Code standards. The owner shall also supply
the following information to the Agency for review and consideration of
requests for a special installation permit:
A)
Full details of design and construction showing equivalency to and departures
from the ASME Code, including blueprints and material showing details of the
construction;
B) Data relating to
the physical and chemical properties of all materials used in
construction;
C) Calculations
showing how the MAWP was derived;
D) An authentic test record for all non-ASME
Code materials used in construction; and
E) Other data as the owner deems relevant or
as the Agency may request in order to establish that the boiler or pressure
vessel will be capable of operating as safely as one built to ASME Code
standards.
3) The Agency
may issue special installation permits to a class of boilers or pressure
vessels meeting the criteria listed in subsection (c)(2) when it deems that the
public interest would be best served by application of the class of boilers or
pressure vessels rather than individual case-by-case determination.
4) The Agency may, as a condition to issuance
of a special installation permit, require the installation of safety features
or prescribed operating procedures for boilers or pressure vessels. The Agency
will use relevant safety data in determining the need for installation of
safety features or operating features.
5) If the Agency denies a request for a
special permit, the owner may request a hearing pursuant to Section
505.84.
d) For boilers and pressure
vessels, other than those covered by subsection (b), to be inspected to
standards other than those specified in this Part, the owner shall request the
use of alternative standards.
1) The owner
shall submit the documentation described in this Section to the Agency and
obtain permission to use the alternative standards.
2) The owner shall specify the reasons why
the boiler or pressure vessel cannot be inspected in accordance with this
Part.
3) The Agency may approve the
use of alternative standards for inspection for a class of boilers or pressure
vessels when it deems that the public interest would be best served by
application of the class of boilers or pressure vessels rather than individual
case-by-case determination.
4) The
Agency may, as a condition of approval of the use of alternative standards for
inspection, require the installation of safety features or prescribed operating
procedures for boilers or pressure vessels. The Agency will use relevant safety
data in determining the need for installation of safety features or operating
features.
5) If the Agency denies a
request for the use of alternative standards for inspection, the owner may
request a hearing pursuant to Section 505.84.
e) For boilers and pressure vessels, other
than those covered by subsection (b), to be repaired to standards other than
those specified in this Part, the owner shall request the use of alternative
standards.
1) The owner shall submit the
documentation described in this Section to the Agency and obtain permission to
use the alternative standards.
2)
The owner shall specify the reasons why the boiler or pressure vessel cannot be
repaired in accordance with this Part.
3) The Agency may approve the use of
alternative standards for repair for a class of boilers or pressure vessels
when it deems that the public interest would be best served by application of
the alternative standards to the class of boilers or pressure vessels rather
than individual case-by-case determination.
4) The Agency may, as a condition of approval
of the use of alternative standards for repair, require the installation of
safety features or prescribed operating procedures for boilers or pressure
vessels, require monitoring the integrity of the alternative repair, or approve
the alternative repair on a temporary basis. The Agency will use relevant
safety data in determining the need for installing safety features or operating
features, monitoring the integrity of the alternative repair, or approving the
alternative repair on a temporary basis.
5) If the Agency denies a request for the use
of alternative standards for repair, the owner may request a hearing pursuant
to Section 505.84.
f)
Owners shall meet the requirements of Section
505.170
in all cases involving use of alternative standards for non-ISI boilers or
pressure vessels.
