S M ~ , = ~ solar F multiple for reference receiver pump design
Pth,Rp,REF = thermal power to EPGS in reference receiver pump
system (watts)
XRP = scaling exponent for receiver pump
CSP,REF = cost of reference storage pump ($)
Pth,Sp,REF = thermal power to EPGS in reference storage pump
system (watts)
xsp = scaling exponent for storage pump.
Default values are as follows:
CRP,REF (CRPREF) = $2.1 x IO6
THTRP,REF (TRPREF) = 170.0 m
P~~,RP,HEF (PRPREF) = 2.6 x lo8 watts
X R (XRP) ~ 0.85
CSP,REF (CSPREF) = $4.70 x lo5
Pth,Sp,~~~ (PSPREF) = 3.0 x lo8 watts
xsp (XSP) = 0.15
V.A-7. Piping-Piping costs are assumed to scale with tower height and with
pipe diameter in relation to a reference system (Reference 39).
CCPIPE = THT(~PHCHOT,REF
+ ~PC~COLD,REF)
(-1 XPIPE (V.A - 13)
DREF
where t p = ~ multiplier on THT to give total hot piping run as
described in Section 1II.G-4
CHOT,REF = reference hot pipe cost, including pipe, insulation,
fittings, hangers, supports, installation ($/m)
tpc = multiplier on THT to give total cold piping run (can be
different from t p if ~ expansion allowance is less)
CCOLD,REF = reference cold pipe cost, as above ($/m)
D = pipe diameter (m)
DREF = reference pipe diameter (m)
xp~p~ = scaling exponent for piping.
