fallen through, citing Hydro-Québec's "concerns about unanticipated costs". Graham's announcement was contested by analysts who blamed the collapse of the deal on the difficult political situation in New Brunswick, six months before a scheduled provincial election. According to leaked internal documents, the proposed sale of NB Power and a proposed post-refurbishment staff reorganization of the company had a negative impact on workers' morale at the Point Lepreau Nuclear Generating Station and was becoming a safety concern. Over 600 workplace injuries occurred at Point Lepreau between January 2009 and June 2010, including 7 "lost time", 13 "restricted work" injuries and 32 incidents requiring medical aid. According to the internal reports, delays were costing NB Power C$33 million a month: "C$11 million in capital costs and C$22 million for replacement power and interest". On 9 October 2010, NB Power announced that AECL would have to remove all 380 calandria tubes from the reactor and reinstall them a second time, an operation which took a year earlier in the refurbishment program. The calandria tubes, roughly and , form the boundary to the moderator tank (calandria) through which the fuel channels are installed. According to an internal report dated 30 June 2010, the problem "is likely the result of damage to the tube sheet bores caused by the cleaning operation in a previous work series". According to an October 2010 estimate, the generating station was scheduled to be back on stream in the fall of 2012, three years later than first expected. First re-connected to the grid on 23 October 2012, on 23 November 2012 Point Lepreau restarted commercial power production with a final refurbishment cost approximately "$1 billion over its original budget". Advanced Small Modular Reactors On 26 June 2018, the government of New Brunswick committed 10 million dollars toward the establishment of an advanced Small Modular Reactor Research Cluster. This was followed by announcements of the participation of ARC Nuclear (9 July 2018) and Moltex Energy (13 July 2018), each investing 5 million dollars to progress research and development of their advanced technologies. Since that time significant development has taken place, including discussions on establishing a supply chain within the province. As indicated on 25 July 2019, NB Power envisions commercial demonstrations of both reactor types at the Point Lepreau site if these advanced technologies successfully complete Phase 2 of the CNSC Vendor Design review and their financial and project planning predictions
