What?  No way to detect neutrons?  We can even detect neutrinos.

Here are 3 ways people say they detect neutrons:

• Absorptive reactions with prompt reactions - low energy neutrons are typically detected indirectly through absorption reactions. Typical absorber materials used have high cross sections for absorption of neutrons and include helium-3, lithium-6, boron-10, anduranium-235. Each of these reacts by emission of high energy ionized particles, the ionization track of which can be detected by a number of means. Commonly used reactions include ³He(n,p) ³H, ⁶Li(n,α) ³H, ¹⁰B(n,α) ⁷Li and the fission of uranium.^[3]

• Activation processes - Neutrons may be detected by reacting with absorbers in a radiative capture, spallation or similar reaction, producing reaction products that then decay at some later time, releasing beta particles or gammas. Selected materials (e.g., indium,gold, rhodium, iron (⁵⁶Fe(n,p) ⁵⁶Mn), aluminum (²⁷Al(n,α)²⁴Na), niobium (⁹³Nb(n,2n) ^92mNb), & silicon (²⁸Si(n,p) ²⁸Al)) have extremely large cross sections for the capture of neutrons within a very narrow band of energy. Use of multiple absorber samples allows characterization of the neutron energy spectrum. Activation also allows recreation of an historic neutron exposure (e.g., forensic recreation of neutron exposures during an accidental criticality).^[3]

• Elastic scattering reactions (also referred to as proton-recoil) - High energy neutrons are typically detected indirectly through elastic scattering reactions. Neutron collide with the nucleus of atoms in the detector, transferring energy to that nucleus and creating an ion, which is detected. Since the maximum transfer of energy occurs when the mass of the atom with which the neutron collides is comparable to the neutron mass, hydrogenous^[4] materials are often the preferred medium for such detectors.^[3]

But the “equivalent trade” being hypothesized by the experimenters would have to be the change in atomic weights of the nickel nuclei.  That extra weight indicates some neutrons were flying around.  As you know, there is no way to detect neutrons, and they aren’t expected to damage anything useful, like property.  They just kill people.  But it takes time.  Let the experimenters enjoy their lives, but watch for unusual tumors or other defects to show up.  If they don’t, then great!  Lots of cheap power from now on.  Otherwise, we’ve lost the time investigating this apparent crack in the faithful’s physics dogma.
