The present invention relates to a method for manufacturing a nuclear fuel cladding tube for reducing the deposition of a crud and a method for reducing the deposition of a crud on a nuclear fuel cladding tube, and more particularly, to a method for manufacturing a nuclear fuel cladding tube for reducing the deposition of a crud, which includes the step of: forming a tube for the nuclear fuel cladding tube (step 1); polishing the inner and outer surfaces of the tube (step 2); and etching the outer surface of the polished tube with acids (step 3). Accordingly, the present invention can reduce a deposition rate of the crud. 본 발명은 크러드 부착 저감을 위한 핵연료 피복관의 제조방법 및 핵연료 피복관의 크러드 부착 저감방법에 관한 것으로, 상세하게는 핵연료 피복관용 튜브형 관을 형성하는 단계(단계 1); 상기 관의 내면 및 외면을 연마하는 단계(단계 2); 및 연마된 관의 외면을 산으로 에칭하는 단계(단계 3);를 포함하는 크러드 부착 저감을 위한 핵연료 피복관의 제조방법에 관한 것이다.
