Only if stating the true facts as reported by the Nuclear Energy Agency is "disingenuous".
On 17 May, analyses performed by TEPCO indicate that significant fuel melting occurred in the unit 1 reactor core with relocation of molten fuel to the lower portion of the reactor vessel. Further, the high-temperature molten fuel (greater than 2 800°C) appears to have caused small leaks in the lower head of the reactor pressure vessel....
On 7 June 2011, the Government of Japan releases a report prepared by the Government Nuclear Emergency Response Headquarters for the IAEA Ministerial Conference on Nuclear Safety (20-24 June 2011, Vienna, Austria). This report includes analyses of the damage to the cores at units 1 to 3. The analyses show that unit 1 has suffered extensive fuel melting and that the reactor pressure vessel has been breached.
1. Introduction
The triple core meltdown at Fukushima Dai-ichi power plant on
March 11, 2011 is the worst nuclear catastrophe after Chernobyl in
1986. The substantial losses of this accident have aroused in the
public opinion an old age debate: Is nuclear power safe?

How Fukushima Dai-ichi core meltdown changed the probability of nuclear accidents?

Analyses are performed of the first core melt behavior of the Unit 1, Unit 2 and Unit 3 reactors of Fukushima Daiichi Nuclear Power Station on 11–15 March 2011 as well as the re-melt (melt again) behavior in another chaotic period of 19–31 March 2011. Analyses are based on a measured data investigation and a simple model calculation.I
