Prize Competition
The Prime Engineering Prize Competition is a biannual event that provides students in mechanical engineering an opportunity to showcase their skills by solving real-world engineering problems related to next-generation clean nuclear energy. The competition challenges students to use SolidWorks and Ansys or Abaqus Finite Element Analysis to analyze the stress in a nuclear pressure vessel and submit their solutions. It is open to undergraduate and graduate students, providing a chance for young engineers to gain recognition and potentially secure an internship or full-time position at Prime Engineering. The competition offers a grand prize of $1000, the Annual Problem Solver Trophy, and it also recognizes the importance of safety and the critical role of analysis in the nuclear industry.

Problem:
You are assigned the task to determine 1) the thickness of a circular flat plate based on an allowable stress intensity of 2.5ksi and 2) the membrane and bending stress intensities at the junction between the flat plate and pipe by use of a stress classification line.
The vessel is constructed from AISI 304H and consists of an ASME B16.5 Weld Neck Flange size 16 NPS Sch 40 that is welded to a pipe of size 16 NPS Sch 40 and then welded to a flat circular plate of 24” of unknown thickness. Assume the outer edge of the 24” diameter plate is fixed.
Use SolidWorks to model the vessel and then use Ansys or Abacus to perform a finite element analysis with the following conditions:
-
Internal pressure: 300 psi
-
Temperature: 1200°F, adiabatic conditions
Deliverables:
-
A drawing showing dimensions of the pressure vessel
-
A one page report identifying the bending and membrane stress intensities using a stress classification line (SCL)
-
Proposed thickness of flat plate
