Take 159.6 mg white, anhydrous CuSO4 or 249.7 mg blue pentahydrate (CuSO4.5H2O), dissolve in 90 mL distillled water, add 1 mL diluted ammonia (1M NH3) and finally fill up to exactly 100.0 mL with distilled water to get the final 10mM alkaline (ammoniacal) CuSO4solution.
You obtain 10 millimoles of ferric chloride and dissolve it in a liter of water.
1.21 g Tris-HCl, QS water to 1L. Scale appropriately.
Molarity of 1X PBS is 10mM. To prepare 20mM PBS take 16g of NaCl, 0.4 g KCl, 2.88 g Na2HPO4 0.48 g KH2PO4 in 800 ml of distilled H2O. Adjust the pH to 7.4 with HCl. Add H2O to 1 liter.
You are orobably thinking of the small cylinders which make up the fuel rods. These are 10mm diameter and about 10mm long, and are packed end to end inside the zircaloy sheath to make a fuel rod. The material is uranium dioxide with the uranium enriched to about 5% U-235.

To prepare the buffer using solid form reagents, prepare a 0.1 M ammonium acetate solution by dissolving 7.7 g ammonium acetate in a 1000 ml water. Adjust 1 L of this solution to pH 4.5 by adding acetic acid (about 8 ml) and 5 ml of 1 M p-TSA (equivalent to 5 mM p-TSA).

This might not be the best answer but, preparing a buffer solution allows one to keep the pH value the same when small amounts of acids or bases are added. Buffer solutions resist change in pH. Source: My Chemistry teacher's PowerPoint
