“…and crud examination (Table 5-3). PIFAG. The PIFAG, discussed in Tessler et al 1987(WAPD-TM-1614, was used to nondestructively measure the fissile fuel content of 524 spent fuel rods from the modules. Cell locations of the 524 rods are shown in Figures 5-2 through 5-13.…”

“…The PIFAG used the method of active neutron interrogation and delayed neutron counting (see Tessler et al 1987, WAPD-TM-1614 to determine the fissile uranium loading of each rod. The PIFAG was assembled in a hot cell at Naval Reactors ECF.…”

“…With small materials (for example, fuel pellets, flowing liquids) it may be more convenient to leave the irradiating source stationary and move the material. 9 In either case, something is being shuffled back and forth while delayed neutrons are being generated and counted.…”
