This report describes the case of a 62-year-old woman who was previously diagnosed with stable angina. Coronary angiography revealed clinically significant stenosis in the midle of the left anterior descending (LAD) artery, the first diagonal branch, the distal left circumflex (LCX) artery and the proximal posterior descending artery (PDA). After administering aspirin and clopidogrel, the patient underwent implantation of sirolimus-eluting stents in -metal stents were implanted in the distal LCX artery and the proximal PDA. Nineteen months later, folow-up coronary angiography revealed aneurysmal dilation at the midle LAD artery and the first diagonal branch. Forty-six months after implantation of the sirolimus-eluting stents, the size of the coronary aneurysm had increased to 12.4 mm; however, no sign of aneurysmal dilatation was observed at the bare-metal stent sites. This suggested that the implantation of the sirolimus-eluting stent was partialy responsible for causing the coronary aneurysm.

A design of a primary cooling system, which removes the heat generated from the core, is dependent on a purpose of a research reactor. A reactor can require variable operating ranges for the primary cooling system. To operate the variable operating range, the primary cooling pump is designed with an inverter or a control valve in the system. The system pressure losses are calculated by the analytic and the numerical methods for the required flow rates estimated from the required core powers and temperature differences. It can be designed that the pump curve is moved by the rpm control with an inverter for the variable pump operating range. If a control valve is installed in the system, a pump curve can be used for the variable range.
