PBMR district heating

[Alessandro]

Given the conclusions of the paper " The pebble bed modular reactor,
desalination challenges and options ",
http://www.inderscience.com/search/index.php?action=record&rec_id=7011&prevQuery=&ps=10&m=or
I'm just curious, the PBMR core heats up helium from 500 to 900 °C,after
that is discharged at 140-160
°C about, could it be possible to heat up water
at temperatures high enough for district heating (or district cooling in the
hot months),of course with negligible or no looses at all in
electricity efficiency production?Have you got any estimate about max
water temperature achievable with helium at 140-160 °C?
What's exactly the max "net" thermal power producible for a PBMR
module? Could it be correct a value of 220 MW thermal per reactor (in the
paper the author claims with no more details " the rejection of
waste heat (about 200 MW) at temperatures of up to 120°C to cooling
water circuits " )

I believe the question is very interesting and useful because, besides
desalination purposes, for example a four modules 400 MW_th plant
could produce together 5/5,5 billions of kWh/year and in the cold
months something like about 300 thousands cubic meters/year of natural gas
equivalent for heating and hot water; moreover,in the hot months (and
particurally in the hot climates) it could
chill with hot water-fuelled absorption chillers the equivalent of
about 50 thousands of houses.
(I assumed a need of 1 kW " chill " (about 3400 Btu/hour) per every
30 m^3 of dwellings, 3000 hours of operation per year and a COP of 0,6
for the absorption chiller)
