BWR
& PWR Containment Analysis
AES’s
BWR
containment
analysis
capabilities
extend
to
all
BWR containment
designs, i.e., Mark I, II, and III designs. Our staff members that
support the BWR
containment designs have been together for more than 20 years,
providing specialized engineering services to over one-half of all BWR
plants in the US. We retain the most experienced group of BWR non-NSSS
Containment Design engineers in the industry. In addition, we maintain
operational copies of the NUREG 0661 hydrodynamic loads generation
software developed for the Mark I program as well as the software to
perform the Torus Attached Piping (TAP) analysis in accordance with the
requirements of NUREG-0661.

- Hydrodynamic
Loads Development
|
AES has
retainedextensive experience in LOCA related loads on primary
containment, piping and internal containment structures. We have
developed loads for Mark I, Mark III and ABWR containments. We have
maintained complete copies of NUREG 0661 and the Mark I Containment
Long Term Program Library. Additionally AES maintains the capability to
run the GE developed suite of Mark I hydrodynamic load generation
programs RVFOR, TQFOR, QBUBS, RVRIZ, CONDFOR and LOCAFOR.
AES
maintains the capability to analyze Mark I piping (torus attached
piping) in accordance with requirements of NUREG-0661. AES has written
a proprietary software (STARCON) which can run a combined analysis for
a Mark I torus coupled to a torus attached piping system. This allows
us to reanalyze torus attached piping to evaluate system modifications
using a methodology consistent with the original methodology used for
most Mark I plants and under the 50.59 process (no change in
methodology).
AES has
performed numerous evaluations for Safety Relief Valves (SRVs) and the
associated tail pipes, including replacement of SRVs, set point
changes, tolerance evaluations, reflood evaluations on subsequent
actuations, and evaluation for extended power uprate (EPU) conditions.
