With reference to particle data group, up quark mass is 2.15 MeV/c2 and down quark mass is 4.7 MeV/c2. Up and down quark mass ratio is 0.46(5). In the earlier published paper titled: “Super symmetry in strong and weak interactions”, the authors proposed a simple method for estimating the six quark masses. With reference to the earlier proposed results, up quark mass is 4.4 MeV/c2 and down quark mass is 9.473 MeV/c2. By considering the up and down quark rest masses, in this paper the authors proposed very simple methods for estimating the nuclear stability and nuclear binding energy and successfully extended the quark model to low energy scale nuclear physics. Topics covered are: 1) Hint of final unification and Up and Down quark rest masses, 2) Strong coupling constant, 3) Nucleon rest masses, 4) Nuclear stability, 5) Nuclear binding energy, 6) Strong interaction range, 7) Nuclear charge radius, 8) Rms charge radius of proton, 9) Rms charge radii of atomic nuclei and 10) Magic numbers. At the stable mass number of Z, nuclear binding energy seems to be proportional to the sum of 2Z up quarks rest energy and Z down quarks rest energy. Interesting point to be noted is that, binding energy near to stable mass number seems to be independent of the mass number. Finally an attempt is made to fit the SEMF energy coefficients. With further research and analysis, strong coupling constant and gravitational constant both can successfully be implemented in low energy nuclear binding energy scheme.
