Theoretical Investigations on Sodium Boiling in Fast Reactors

Design basis accident studies. Final report

“…Then N_-&V E(N(N-1)) = 2 N(N-1)(3V) c. (3)(4)(5)(6)(7)(8)(9)(10) N=2 Ni = (EV) 2 1 (El/') 4e-EV . Since the average of the square of a. statistic is the maximum likelihood estimator of the variance ( 21,), <( f K.)1>= v (K), (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22) .and since Ni is a poisson statistic Since the diffusion area (L2) is defined to be (D/Ea), I<* can be expressed as a function of Eir. An expression for w2 can be developed using the definition of w2 in the limit of thin spherical shells (See equation ) and the expression for w(r), ..…”

Incipient Boiling Pressure Pulse of Sodium under Forced Convection by Direct Heating

“…The friction of the expelling liquid column is considered but that of the vapor phase can be neglected. The compressibility of where u=dz/dt, ( 2 ) and the friction loss APrt is generally given by where, since the liquid flow can be assumed to be laminar in the early stages of the boiling process, the friction factor ( 5 ) Moreover, as a temporary standard, if the pulsations are relatively rapid, no appreciable heat transfer and vaporization will occur, and the compression may be assumed to be adiabatic :…”

Incipient Boiling Pressure Pulse of Sodium under Forced Convection by Direct Heating

“…Using the coordinate system shown in Fig. 12 where u=dz/dt, ( 2 ) and the friction loss APrt is generally given by where, since the liquid flow can be assumed to be laminar in the early stages of the boiling process, the friction factor E = 641%…”
