public is invited to comment on the
adequacy of this technical information,
including the following:
jlentini on PROD1PC65 with NOTICES
I. Technical Basis
1. RIL 0801 Figure 1 provides the
measured embrittlement threshold for
all fresh and irradiated cladding
specimens investigated during the ANL
research program. Hydrogen dependent
post-quench ductility regulatory criteria,
similar to the lines on this figure, may
be established from these experimental
results.
a. Is the technical information
presented within NUREG/CR–6967
sufficient in scope and depth to justify
specific regulatory criteria applicable to
all current zirconium cladding alloys?
b. Is the technical information
presented within NUREG/CR–6967
sufficient in scope and depth to justify
periodic testing on as-fabricated
cladding material?
c. Is the technical information
presented within NUREG/CR–6967
sufficient in scope and depth to address
sensitivities to alloy composition, trace
elements, manufacturing practices, fuel
rod burnup, and transient temperature
profile?
2. Section 2 of NUREG/CR–6967
details the experimental techniques and
procedures employed at ANL to assess
cladding properties.
a. Were the experimental techniques
and procedures adequate for their
intended purpose of defining acceptable
fuel criteria (e.g., specimen preparation,
specimen size, heating/cooling rates,
ring-compression techniques, test
temperature, acceptance criteria for
post-quench ductility and breakaway
oxidation, etc.)?
b. Is the technical information
presented within NUREG/CR–6967
sufficient in scope and depth to address
uncertainties related to and repeatability
of measured results?
II. Performance-Based Testing
Requirements
1. Due to potential sensitivities to
manufacturing processes, performance
based testing may be required to
characterize the loss-of-coolant accident
(LOCA) performance of new cladding
alloys.
a. Section 2.1 of NUREG/CR–6967
details all of the fresh and irradiated
cladding specimens investigated during
the ANL research program. Is the extent
of the ANL material database sufficient
to justify the applicability of
experimental results to future cladding
alloys?
b. Conducting testing on irradiated
specimens is more difficult and
expensive than similar tests performed
VerDate Aug<31>2005

Jkt 214001
on unirradiated specimens. Does a
sufficient technical basis exist to justify
testing on hydrogen charged,
unirradiated cladding specimens as a
surrogate for irradiated fuel cladding?
2. Due to potential sensitivities to
manufacturing processes, routine testing
may be required to verify material
performance. Are there difficulties or
limitations with periodic testing that
would make such a requirement
impractical?
III. Implementation
1. Implementing new regulatory
criteria for 10 CFR 50.46(b) may
necessitate further testing and new
licensing activities (e.g., revised
methods, updated safety analyses, etc.).
What is the cost-benefit for
implementing new regulatory
requirements similar to those discussed
in RIL 0801?
2. Implementing hydrogen-based
regulatory criteria may require the
development of high confidence
corrosion and hydrogen pickup models.
a. What type of information is needed
to develop such models and is such
information readily available?
b. What performance indicators (e.g.,
pool-side measurements, hot cell
examinations, etc.) could be used to
validate models?
c. What additional regulatory
requirements would be necessary to
assure that the fuel is performing in
accordance with the approved models?
How will compliance with the rule be
demonstrated on a cycle by cycle basis?
3. Crud deposits on the fuel cladding
surface may affect fuel stored energy,
fuel rod heat transfer, and cladding
corrosion.
a. What role does plant chemistry and
crud deposits play on these items?
b. How should normal and abnormal
levels of crud deposits be addressed
from a regulatory perspective?
The NRC is seeking public comment
to receive feedback from the widest
range of interested parties and to ensure
that all information relevant to revision
of the embrittlement criteria in 10 CFR
50.46 is available to the NRC staff. The
NRC will review public comments
received on this technical information
and incorporate appropriate changes
before starting to develop the proposed
revisions to the regulations. Comments
will be discussed during a 10 CFR
50.46(b) public workshop tentatively
scheduled for September 2008 (specific
date and location to be noticed
separately).

SUPPLEMENTARY INFORMATION:
I. Introduction
The U.S. Nuclear Regulatory
Commission (NRC) has issued for public
comment a draft regulatory guide in the
agency’s ‘‘Regulatory Guide’’ series.
This series was developed to describe
and make available to the public such
information as methods that are
acceptable to the NRC staff for
implementing specific parts of the
NRC’s regulations, techniques that the
staff uses in evaluating specific
problems or postulated accidents, and
data that the staff needs in its review of
applications for permits and licenses.
The draft regulatory guide (DG), titled,
‘‘General Design Guide for Ventilation
Systems of Plutonium Processing and
Fuel Fabrication Plants,’’ is temporarily
identified by its task number, DG–3034,
which should be mentioned in all
related correspondence.
Proposed Revision 1 of Regulatory
Guide 3.12 describes a method that the
staff of the NRC considers acceptable for
use in complying with 10 CFR
70.23(a)(3) and (a)(4) with respect to the
design of ventilation systems for
plutonium processing and fuel
fabrication plants. At plutonium
processing and fuel fabrication plants, a
principal risk to health and safety is the
release and dispersal of radioactive
materials. The prevention of such
release and dispersal is an important
function of the ventilation systems. To
meet these objectives, this guide
provides recommendations for
achieving defense in depth and for

minimizing the release of radioactive
materials to the environment.
Each applicant for a license to possess
and use special nuclear material in a
plutonium processing and fuel
fabrication plant as defined in 10 CFR
70.4, ‘‘Special Nuclear Material,’’ must
satisfy the provisions of 10 CFR 70.23,
‘‘Requirements for the approval of
applications.’’ Paragraphs (a)(3) and
(a)(4) of 10 CFR 70.23 require that the
applicant’s proposed equipment,
facility, and procedures be adequate to
protect health and minimize danger to
life or property.
II. Further Information
The NRC staff is soliciting comments
on DG–3034. Comments may be
accompanied by relevant information or
supporting data, and should mention
DG–3034 in the subject line. Comments
submitted in writing or in electronic
form will be made available to the
public in their entirety through the
NRC’s Agencywide Documents Access
and Management System (ADAMS).
Personal information will not be
removed from your comments. You may
