Vendors, consultants, or suppliers

contracted

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.
