This practice may be abandoned if determined I unnecessary as a result of no deficiencies being found in the j first 6 joints checked. t= 2 4.3 The loop pipe 0D should be protected from foreign debris and g where possible. it should be wrapped with a protective covering such as polyethelyne. The internal surface of the steam generators. reactor coolant punp casings, and primary 3 coolant piping shall be kept clean by removing all debris and dust as necessary, until system is sealed up. Refer to pro. ject Procedure XIII-4. h 4.4 Prior to final alignment of primary reactor coolant piping 'i all weld end preparations on sipe, fittings and nozzles shall = be liquid penetrant examined.
