NUCLEAR REGULATORY COMMISSION

[NRC-2017-0040]


Initiatives To Address Gas Accumulation Following Generic Letter 
2008-01

AGENCY: Nuclear Regulatory Commission.

ACTION: Draft regulatory issue summary; withdrawal.

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

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is withdrawing 
draft Regulatory Issue Summary (RIS) 2017-XX, ``Status of Regulatory 
Actions Taken to Address Gas Accumulation in Emergency Core Cooling, 
Decay Heat Removal, and Containment Spray Systems.'' The NRC has 
decided to withdraw this RIS after reviewing the comments received 
during the public comment period.

DATES: The date of the withdrawal is September 21, 2017.

SUPPLEMENTARY INFORMATION: The NRC is withdrawing draft RIS 2017-XX 
``Status of Regulatory Actions Taken to Address Gas Accumulation in 
Emergency Core Cooling, Decay Heat Removal, and Containment Spray 
Systems'' (ADAMS Accession No. ML16244A787). The NRC published a notice 
requesting public comment on this RIS in the Federal Register on 
February 13, 2017 (82 FR 10504). The NRC issues RISs to communicate 
with stakeholders on a broad range of matters. The draft RIS informed 
affected entities that licensees who choose not to implement two 
voluntary industry efforts to address gas accumulation issues must 
ensure that systems remain operable with respect to the potential for 
accumulation of gas, in accordance with their plant-specific technical 
specifications and their plants' licensing basis. Generic programmatic 
and licensing concerns with respect to gas accumulation were identified 
through the NRC's review of responses to Generic Letter (GL) 2008-01, 
``Managing Gas Accumulation in Emergency Core Cooling, Decay Heat 
Removal, and Containment Spray Systems,'' dated January 11, 2008 (ADAMS 
Accession No. ML072910759).
    As a result of its review of comments received on the RIS, the NRC 
has determined that final issuance of this RIS is not necessary. The 
agency received comments on the RIS from the Nuclear Energy Institute 
(ADAMS Accession No. ML17079A134), Southern Nuclear (ADAMS No. 
ML17081A016), and the Tennessee Valley Authority (ADAMS No. 
ML17081A017). Among other things, these comments pointed out that much 
of the guidance discussed in the RIS was issued after GL 2008-01, and 
suggested that discussing that guidance might confuse licensees about 
whether they need to perform additional actions in response to GL 2008-
01. The NRC previously issued plant-specific closure letters following 
its review of licensee information submitted in response to GL 2008-01 
and determined that no additional action was required.

    Dated at Rockville, Maryland, this 8th day of September 2017.

    For the Nuclear Regulatory Commission.
Alexander D. Garmoe,
Chief (Acting), Generic Communications Branch, Division of Policy and 
Rulemaking, Office of Nuclear Reactor Regulation.
