Performance qualification

Do we need to do performance qualification for GLR reactor which is recently installed (GLR found crack so sent out for reglassling) reglassing done and now its installed in its old location.
installation & operational qualification is done and my doubt is do we need to perform performance qualification or not?

Yes. Performance Qualification is required. This is because tyou have replaced the old glass lining due to crack (Re-glassing). In order to understand performance of this reactor after re-installation the PQ is required. Re-IQ, Re-OQ was also performed after re-installation.

Do we need to perform the performance qualification when the Reactor send to outside for Jacket replacement ?

Yes, we need to perform re-qualification (IQ, OQ, PQ) of the reactor to ensure that it has been re-installed as per the previous installation recommendations, drawing, and process. Its functional specifications meet the requirements and it performs as expected with a newly replaced jacket.
