NUCLEAR REGULATORY COMMISSION
[NRC-2015-0195]
Inservice Inspection of Ungrouted Tendons in Prestressed Concrete
Containments
AGENCY: Nuclear Regulatory Commission.
ACTION: Regulatory guide; withdrawal.
-----------------------------------------------------------------------
SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is withdrawing
Regulatory Guide (RG) 1.35, ``Inservice Inspection of Ungrouted Tendons
in Prestressed Concrete Containments.'' The regulatory guide is being
withdrawn because of changes in NRC regulations, which render the RG
obsolete. The withdrawal does not affect the licensing bases of current
licensees approved to use RG 1.35.

SUPPLEMENTARY INFORMATION: The NRC is withdrawing Regulatory Guide 1.35
because it has been superseded by changes in NRC regulations as set
forth in section 50.55a of Title 10 of the Code of Federal Regulations
(10 CFR), ``Codes and Standards.'' The change in the regulations
provides more complete and more up to date guidance.
The withdrawal of RG 1.35 does not alter any prior or existing
licensing commitments based on its use. Although a regulatory guide is
withdrawn, its use in existing licenses is still valid, and changes to
the licenses can be accomplished using other regulatory products.
Withdrawal of a regulatory guide means that the RG no longer provides
useful information or has been superseded by other guidance,
technological innovations, congressional actions, or other events. A
withdrawn RG should not be used for future NRC licensing activities.
Since RG 1.35 was last revised in 1990, ASME Boiler and Pressure
Vessel Code Section XI, Subsection IWL was issued. This subsection
addresses the examination and repair/replacement of the reinforced
concrete and the post-tensioning systems of concrete containments. The
NRC incorporated the requirements of the 1992 Edition of the ASME
Boiler and Pressure Vessel Code with the 1992 Addenda of Subsection IWL
into its regulations, with specified modifications and limitations, in
an amendment to section 50.55a, which was published in the Federal
Register on August 8, 1996 (61 FR 41303). The rulemaking also required
that all nuclear power plants in the United States develop and
implement a containment inspection program in accordance with Section
XI,
[[Page 52068]]
Subsection IWL (as applicable for the type of containment) by September
9, 2001. Subsequent, NRC amendments to 10 CFR 50.55a have incorporated
by reference later editions of Subsection IWL, with modifications and
limitations which continue to address issues addressed by RG 1.35.
The guidance provided in RG 1.35 has been incorporated into later
revisions of Subsection IWL, or preserved in 10 CFR 50.55a. As a
result, RG 1.35 has become redundant and is no longer needed.
Dated at Rockville, Maryland, this 21st day of August, 2015.
For the Nuclear Regulatory Commission.

Engineering, Office of Nuclear Regulatory Research.
