2 MPa is ~ 20 atm or ~ pressure at 200m depth.
Ofc there is a difference between static and dynamic loads, but on low depths such a change in pressure that doesnt sound as all that lethal considering the crash dive depth of the desighn.
Morever, more or less post Alfa class the Soviet SSN/SSGN desighns were optimised (in terms of hydrodynamic shaping and structural desighn) to improve survivability against (nuclear) depth charges.
