5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM
The core memory size MXX for the variable dimensions is limited to 100 K and the total necessary core memory size is 128 K for the accumulation calculation by the present version of the code.
MXX = NNUM* (NFIS = 4* NPAR + 9)
+ ISC* (NGS + 1) + 10* (NCARD + 1),
where, MXX = necessary core memory size for variable dimension variables,
NNUM = number of nuclides in the nuclear data library,
NCARD = number of cards to revise the nuclear data library, NGS = number of groups for neutron reaction cross sections (27),
NFIS = number of kinds of fission yields (10), NPAR = the maximum number of the direct mother nuclides allowed for each nuclide (6),
ISC = number of nuclides having neutron reaction cross sections (100).
MXX = NMAX* (17 + 4*NPAR + NFIS)
+ LCH* (6 + 2*NCHA) + ISC* (1 + NGS + NIRR)
+ NIRR* (10 + NFIS) + NGS + NOUT* 5,
where,NMAX = number of nuclides considered in the calculation, NPAR = the maximum number of the direct mother nuclides allowed for each nuclide,
NFIS = number of kinds of fission yields,
LCHA = the limitation for the length of a linear chain,
NCHA = the maximum allowable number of linear chains allowed for the calculation of accumulation of each nuclide,
NIRR = number of time steps for expressing the irradiation and cooling history,
NOUT = the maximum number of time points for the output of results.
