Vendors, consultants, or suppliers

to perform safety-related
activities
will be qualified
and maintained
under existing Callaway Plant Unit I OQAM procedures
and controls.7. What is the current status of the development
of the plant design (i.e., conceptual, preliminary, or finalizing)?
Has the applicant
established
a schedule for completing
the design? If so, please describe the schedule.Response: Westinghouse
is using a management
strategy that focuses on completing
parallel design tasks to mitigate potential
emergent or challenging
issues that could threaten completing
the Westinghouse
SMR plant design. [I".C The design is sufficient
to support preparing
and submitting
the DCA. Design work will continue in parallel with the design certification (DC)preparation
and application.
To implement
this management
approach, an integrated
project schedule is being used. Said schedule covers the entire design process. Rolling wave planning is being used -in which detailed activities
are planned for the near-term
two-year period, and major activities
are planned for following
years. This approach is being used to efficiently
plan and address necessary details at the appropriate
time.8. What is the applicant's
current status (i.e., planning, in progress, or complete)for
the qualification
of fuel and other major systems and components?
Has the applicant
established
a schedule for completing
the qualification
testing? If so, please describe the schedule.Response: For design simplification
and licensing
ease, Westinghouse
chose to fuel the Westinghouse
SMR with a shorter version of the highly successful
17x 17 Robust Fuel Assembly (RFA) design. Said design was chosen because of its significant
operating
experience
and excellent
performance.
The fuel itself will be manufactured
and tested at Westinghouse's
fuel plant in Columbia, South Carolina.
Said assemblies
are similar to the fuel assemblies
that power many operating
reactors -as well as the AP10000 reactor -but are shorter in overall length, with an 8-foot active fuel height versus the AP1000 reactor assemblies'
14-foot height. The fuel design also includes optimized
ZIRLOcladding for corrosion
resistance, and other features that mitigate debris-related
failures.Westinghouse
is highly confident
that this fuel will provide the expected Westinghouse
SMR fuel lifetime, while minimizing
unanticipated
outages and fuel failures, and their associated
costs. The fuel management
strategy includes effective
use of uranium; average assembly discharge
burnup is approximately
[ ia,c, which is consistent
with Westinghouse
experience.
]ac Westinghouse
will be seeking an extension
to use [ 1 .The Control Rod Drive Mechanisms (CRDMs) that will operate within the primary system's internal environment
will be based on proven API000 plant technology.

status in the development
of probabilistic
risk assessment (PRA) models needed to support applications (e.g., needed for Chapter 19 of safely analysis reports or needed to support risk-informed
licensing
approaches)?
Does the applicant
plan to use the PRA for any risk-informed applications (i.e., risk-informed
technical
specifications, risk-informed
inservice
inspection, risk-informed
categorization
and treatment, risk-informed
inservice
testing, etc.). What are the applicant's
plans for using the PRA models in the development
of the design? At what level will the PRA be prepared, and when will it be submitted
in the application
process?Response: Westinghouse
is underway.
[Westinghouse
plans to document the PRA when []al.As recommended
in Regulatory
Issue Summary 2012-08, Developing

Testing and Inservice Inspection
Programs Under 10 CFR Part 52: Ameren Missouri does not plan to submit -as part of the COL application
-a request for risk-informed
in-service
inspection (ISI) or in-service
testing (IST) programs.
RIS 2012-08 recommends
establishing
conventional
ISI or IST programs before preparing
a risk-informed
ISI or IST program. Said recommendation
is based on:* Existing design certification
applications
- The Standard Review Plan acceptance
criteria* Applicable
NUREG documents* That COL applications
conform to the idea that conventional
ISI/IST programs were developed before a risk-informed
program Similarly
-for the same reasons described
above- there are no plans to submit a request for risk-informed technical
specifications, categorization
and treatment, or fire protection
programs.
Any request for risk-informed
applications
will be submitted
after the COL application
is approved.14. What is the applicant's

seek approval of either "proposed
major features of the emergency
plans" in accordance
or "proposed
complete and integrated
emergency

process would address the remainder
of the proposed nuclear power plant. For example, would the ML address an essentially
complete plant or would it be limited to the primary coolant system that basically

the integral reactor vessel and internals?
Response: The Westinghouse
SMR will follow the 10 CFR Part 52 approach without implementing
the provisions
in Subpart F for "Manufacturing
Licenses." 21. Describe the expected combination
of manufacturing, fabrication, and site construction
