== Cancellation == Argentine physicists were also critical of the announcement, but found little interest on the part of Perón, who was still at odds with the academic mainstream. González was growing increasingly frustrated with Richter, and in February 1952 told Perón that either Richter left the project, or he did. Perón accepted González's resignation and replaced him with his aide, Navy Captain Pedro Iraolagoitía. Iraolagoitía soon began to protest as well, finally convincing Perón to have the project investigated. Instead of calling upon the local physics community, Perón put together a team consisting of Iraolagoitía, a priest, two engineers including Mario Báncora, and young physicist José Antonio Balseiro, who was at that time studying in England and was asked to return with all haste. The team visited the site for a series of demonstrations between 5 and 8 September 1952. The committee analyzed Richter's work and published separate reports on the topic on 15 September. Balseiro, in particular, was convinced nothing nuclear was taking place. His report critiqued Richter's claims about how the system was supposed to work, especially the claims that the system was reaching the temperatures needed to demonstrate fusion; he stated that fusion reactions would require something on the order of 40 million kelvin, while the center of the electric arc would be perhaps 4,000 to 100,000 kelvin at most. He then pointed out that Richter's radiation detectors showed large activity whenever the arc was discharged, even if there was no fuel present. Meanwhile, the team's own detectors showed low activity throughout. They reported their findings to Perón on 15 February. Richter was allowed to officially respond to the report. The government appointed physicists Richard Gans and Antonio Rodríguez to review the first report as well as Richter's response to it. This second group endorsed the findings of the first review panel and found Richter's response inadequate. On 22 November, while Richter was in Buenos Aires, a military team occupied the site. They found that many of the instruments were not even connected, and the project was pronounced a fraud. Argentines jokingly referred to the affair as the Huele a mula, or "it smells like a con".
== After the project == In the period immediately after the military takeover, Balseiro wrote a proposal to create a nuclear physics institute on the mainland in nearby Bariloche using the equipment on the island. Originally known as the Instituto de Física de Bariloche, it was renamed the Instituto Balseiro in his honour in 1962. Between 1952 and 1955, Richter was effectively under house arrest in Buenos Aires, with an offer from Perón to "facilitate any travel he might have to make". After Perón was deposed in September 1955, the new government arrested Richter on the night of 4 October 1955. He was accused of fraud, and spent a short time in jail. At the time, it was estimated that 62.5 million Pesos had been spent on the project, about $15 million USD ($182 million in 2025). A more recent estimate places the value closer to $300 million in 2003 dollars ($525 million in 2025). Richter remained in Argentina for a time, but began to travel, eventually landing in Libya. He returned to Argentina and was extensively interviewed by Mario Mariscotti for his book on Huemul, which remains the most detailed account of the project. Mariscotti blames the affair primarily on Richter, who Mariscotti states was capable of great self-delusion, adding an autocratic and paranoid management style, and lack of oversight to the ills. Perón remains a controversial figure to this day, and opinions of Richter tend to be colored by how closely the author associates him with Perón. Argentine accounts often refer to Richter as an outright con man, while accounts written outside Argentina generally describe him as a deluded amateur.
== Huemul today == The island remained closed and under military control until the 1970s, when the Army began using it for artillery target practice. In 1995 a tourist company took control of the island, and began to offer tours by boat from docks in Bariloche. The ruins of the historic facilities (at 41°06′23″S 71°23′42″W), can be visited by tourists by boat from the port of Bariloche.
