1) I criticized reservation about preliminary conclusion at the March 5, 2007 meeting of APS (American Physical Society). This is described in:

http://csam.montclair.edu/~kowalski/cf/319galileo.html

An improved version of the SPAWAR experiment (using very thin mylar to protect the detector from the electrolyte) yielded a much more convincing confirmation that a nuclear effect of some kind is indeed triggered by a chemical process. That was the essence of Gordon's claim. Oriani, a retired electrochemist from the University of Minnesota, demonstrated this in 20 consecutive experiments. And my one attempt to replicate Oriani's results was highly successful. For more details see:

http://csam.montclair.edu/~kowalski/cf/327squeeze.html

2) The experiment is simple and relatively inexpensive. Here is what one needs:

a) A d.c. power supply (variable voltage up to 10 V) to deliver no more that 100 mA)
b) A d.c. voltmeter and a d.c. milli-ammeter (to measure the above).
c) Several grams of Li2SO4 (plus common distilled water to make the electrolyte). Two grams of Li2SO4 for 100 cc of H2O.
d) A nickel wire of 0.25 mm diameter (or thicker), to make a cathode. About 15 cm
e) A platinum wire of 0.25 mm diameter (or thicker), to make an anode. About 15
f) CR-39 plastic and very thin mylar (6 microns or less). Also two special glass tubes to make a small cell.
g) Common NaOH, to prepare the etching 6.25 M solution.
h) An oven (or a hot plate with a thermostat) to etch the CR-39 at about 70 C
i) A microscope, most likely available in a biology lab.; preferably with a digital camera attached.

All this is commercially available. The role of a "starter," described at the above URL (see point 10), is not clear at this time. That why experiments without starters are highly desirable. In my opinion Oriani's setup is ideal for a supervised student research project. I would be happy to assist those who might be interested.
