I was wondering if these two documents are available:
Yes, you can find the documents here -
Post the Schedule Analysis, developed from the schedule analysis tool, FUSE.
The Analysis can be found here -
drives the CD-3a scope? Schedule slide shows site prep in the 3a box but this
is not included in CD-3a scope. Answer: available funding and need to get to
cryostat going in 2021-2022?
the relative scope of 3a vs rest of project handled as funding is allocated
yearly? What?s the process?
escalation the highest risk and not availability of DOE funding?
understand the numbers of 34% contingency compared to CD-3a scope of $219M base
and $83M contingency, which is more like 38%. Clarified in response to
question. 34% is for total project
improvements in 3a scope e.g. to and within Ross area?
backup power anywhere in BSI or underground 3a scope?
safety and other safety systems (oxygen monitoring, communications, controls,
fire etc) all part of the CD-3a scope? Where are these requirements captured?
Answers to questions
What is the preferred order of filling the
caverns? Is it 1,2,3,4 or something different?
an interface drawing that shows the relationship between the cavern dimensions
and the cryostat dimensions. The KPPs reference the fiducial mass, which
strictly speaking, will not be known until significant data analysis is
complete. It would be useful to include a drawing showing the relationships
between cavern, cryostat and assumption for obtaining 10 kT fiducial mass, to
indicate there is significant headroom.
bagging or triple bagging? Bug bag(outermost) removed before moving into
transition and laydown. Second bag cleaned and removed. Then final bag removed
in clean area.
assume 2nd cavern available for laydown space while doing 1st
surface computing is assumed and where is it located? Answer: still to be
How much power contingency? do you have at this stage of the design?
