Proposed Rules

NUCLEAR REGULATORY COMMISSION

10 CFR Part 50

RIN 3150-AI53
[NRC-2008-0663]


Industry Codes and Standards; Amended Requirements

AGENCY: Nuclear Regulatory Commission (NRC).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: The NRC is proposing to amend its regulation governing vessel 
head inspection requirements. This amendment would revise the upper 
range of the percentage of axial flaws permitted in a specimen set used 
in the qualification of nondestructive examination systems (procedures, 
personnel and equipment), for the performance of inservice inspection 
(ISI) of pressurized water reactor (PWR) upper reactor vessel head 
penetrations. This amendment is being proposed as a result of the 
withdrawal of a stakeholder's recommendation necessitated by a 
typographical error in the original recommendation with respect to the 
maximum percentage of flaws that should be oriented axially.

DATES: The comment period for this proposed rule ends on September 4, 
2009. Comments received after this date will be considered if it is 
practical to do so, but the NRC is able to ensure only that comments 
received on or before this date will be considered.

ADDRESSES: You may submit comments by any one of the following methods. 
Comments submitted in writing or in electronic form will be made 
available for public inspection. Because your comments will not be 
edited to remove any identifying or contact information, the NRC 
cautions you against including any information that you do not want to 
be publicly disclosed.

SUPPLEMENTARY INFORMATION: See the information provided in the direct 
final rule of the same title, which is found in the Rules and 
Regulations section of this Federal Register Notice. Because the NRC 
considers this rule to be non-controversial, the agency is publishing 
this proposed rule concurrently as a direct final rule. The direct 
final rule will become effective on October 19, 2009. However, if the 
NRC receives significant adverse comments on the direct final rule by 
September 4, 2009, then the NRC will publish a document that withdraws 
the direct final rule. If the direct final rule is withdrawn, the NRC 
will address the comments received in response to proposed revisions in 
a subsequent final rule. Absent significant modifications to the 
proposed revisions requiring publication, the NRC will not initiate a 
second comment period for this action in the event the direct final 
rule is withdrawn.
