Yes, a supercritical mass of fissile material such as uranium or plutonium can accelerate until a nuclear explosion occurs. When the mass reaches a critical point, a rapid chain reaction takes place, releasing a large amount of energy in the form of heat and pressure, resulting in an explosion.
A subcritical mass cannot sustain a nuclear chain reaction, it dies exponentiallyA critical mass can sustain a nuclear chain reaction, but it remains constant neither increasing nor decreasingA supercritical mass not only sustains a nuclear chain reaction but it increases exponentially until the mass explodesA nuclear fission bomb must become supercritical at some time in order to explode.
subcritical - a mass or arrangement of fissionable or fissile material unable to sustain a neutron chain reaction. It can provide a fixed amount of neutron multiplication from a neutron source, but after removal of the neutron source the chain reaction rate drops exponentially.critical - a mass or arrangement of fissionable or fissile material capable of sustaining a constant neutron chain reaction. No increase or decrease. (Nuclear reactors operate at critical)supercritical - a mass or arrangement of fissionable or fissile material capable of not only sustaining a neutron chain reaction, but once initiated the chain reaction rate rises exponentially. (Nuclear fission bombs explode when made supercritical)A nuclear fission bomb must have 2 of these states: subcritical (so that it can't explode until desired) and supercritical (so that it explodes with an effective yield). This requires a rapid "assembly" system using conventional explosives to rearrange the fissile material from subcritical to supercritical in about 1ms. A neutron source starts the chain reaction and the explosion completes in about 1 microsecond.
The fissile fuel is packaged in the bomb as a subcritical mass.The fusing system detects the preset firing condition.A firing pulse is sent from the fusing system to the rapid assembly system.The rapid assembly system uses explosives to repackage the fissile fuel as a supercritical mass.A neutron source fires through the supercritical mass, initiating the chain reaction.The chain reaction increases exponentially until the resulting explosion disassembles the fissile fuel back to a subcritical mass.
The car began to accelerate as the driver pressed down on the gas pedal. We need to accelerate our efforts to complete the project on time. Training can help accelerate muscle growth and improve overall fitness.
When forces acting on a body are unbalanced, the body will experience acceleration in the direction of the net force. This acceleration causes the body to change its velocity, resulting in motion. The body will continue to accelerate until the forces acting upon it become balanced.

She loses her hearing in the ear facing the explosion, until she gets to the Capital and they fix it.

Jupiter does not have a defined surface. currently the "surface" is considered to be the top of the visible cloud deck. Below that temperature and pressure gredually increase until the atmosphere graduall phases into a supercritical fluid, neither liquid nor gas. Below that the supercritical fluid phases into liquid metallic hydrogen. However, before you even reached the supercritical layer, any boat or ship would melt or be vaporized in the extreme heat.
It did for 28 seconds until a fatal gas explosion occured.

TOday there was an there was an explosion at work and all the staff had to leave the building until the fire service said it was OK to go inside again.

Yes, until he reaches terminal velocity.
