Subject: criteria updates

Tomski and Maurice and Lee,

can you take a look at this draft list of criteria questions? Im still thinking whats best to say for sources ......i did it real quick today (since we had power outage last night)so there's probably something missing here

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

List of items, questions to update the criteria for process water (Excluding HVAC/Air Treatment)

General Summary: In the CFS Kick Off Meeting, it was noted that the process water part of CFS used whatever criteria information that CFS had as of Nov 27 2006, to do the RDR process water concept and cost. The ML RF had more information as compared to the rest of the area system, in terms of listing individual water cooled components, although incomplete to conceptualize the LCW piping scheme. It was used as basis and the rest of the area system are scaled from it based on their respective heat load. It was noted that for the EDR, we will update the criteria to update the process water concept to bring it to some matured but still conceptual level to be used as baseline for any value engg, which means that we'll try to conceptualize LCW system, and have a water plant design started in other area system instead of scaling approach used in RDR. We assumed that this process (of criteria updating/gathering) actually starts at EDR and not before.As a starting point of moving to that direction, we're asked to list what information is needed to get the criteria updated.

ML RF: Water Plant at Shaft 7,4 & 6 (5,3,2 are shared with sources)

Expected Contact person: Shigeki Fukuda?

CFS (RDR) Contact: Atsushi and Tomski

Assumptions:

The number of RF per water plant is the same as that in RDR (totals from T. Peterson)

will ignore RTML transfer lines along the tunnel, that would otherwise be a load to said water plants

Summary: We have some filled out tables from Nov 27 2006 that needs to be reviewed to see if the components and numbers are still current (This is probably just a simple "yes" or "no" answer). Second, there are missing items in the table, (Keith suggested having cut sheets of equipment spec with regard to water), not all this needs to be filled, the minimum information for each component that is really needed to evaluate the LCW distribution to this are the following

a) What's the heat load to water and design flow (from this CFS can calculate delta T and flow velocity as well) or Heat load to water and delta T (fom this CFS can calculate the flow and velocity) or Water Flow and delta T (from this CFS can calculate heat load to water and velocity)

b) What's the maximum allowable or exit water temperature (from this we can evaluate the series flow/stacking potential)

BDS: Water plant at Shaft 1.0

Expected Contact Person: Andrei Seryei & Paul Bellomo

CFS (RDR) Contact: Fred Asiri

Assumptions:

All water cooled components here are LCW

All water cooled Magnets are 40 F delta T as long as the max temp (outlet) doesnt exceed 140F

Summary: We have a total heat load for BDS in terms of total KW based on Paul Bellomo's sheet. We also have the Power Supply load and flow at 18F delta T from Paul Bellomo. We believe this is still current. To evaluate the LCW distribution further to this area. We need to have items a above for any water cooled components in this area and

Establish locations of this total KW heat load along the distance of BDS. If not, an assumption of % of this load along the length (maybe unformly distributed as a starting point) . Also the power supply locations or distribution along the distrance of BDS. Cable distribution (that is 50% of this cable to service tunnel and 50% to beam tunnel)

DR: Water Plant at Shaft 12 and 13:

Expected Contact:Andy Wolski

CFS (RDR) Contact: Tomski

Assumptions: All components need LCW

Summary: We have a total KW numbers from Oct 16 2006 email. We need to find out if those are still current. Also locations (approximate or guess) of these water cooled components and listing similar to item a in ML above. We have Power supplies total numbers from Paul Bellomo at 18F delta T.

RTML: Water plant at Shaft 10 and 11

Expected Contact Person: PT

CFS (RDR) Contact: JeanLuc and Gerry

Assumptions: No (or ignore) small heat load on the transfer line from DR to RTML

We have total KW numbers dated Oct 27 2006 email. same discussion as BDS

IR: (There was no IR process water number in RDR, and there's Working Group that is developing criteria for this)

Expected Contact Person: Andrei

Expected CFS contact: Fred
