1 Scope

NB/T 20358.4-2018 is Part 4 of the Chinese budget quota series for nuclear power plant construction, and it prices the installation of process equipment in the nuclear island. A budget quota is not a technical specification: it is the official book of unit rates telling an estimator how much labour, machinery and consumable material a defined unit of work consumes, and it is what a Chinese reviewer checks a submitted price against. This part covers the heavy mechanical scope of the nuclear island - the reactor pressure vessel and its internals, steam generators, pressurisers, main coolant pumps, heat exchangers, tanks and vessels, filters and demineralisers, cranes and handling equipment, and the ventilation and air conditioning plant - together with the rigging, temporary supports, alignment, bolting and pressure testing that installation requires. Each quota item states the work content it includes, the unit of measurement, the labour hours by trade, the machine-shift consumption by equipment type, and the material quantities with their waste allowances. The explanation at the front of the volume sets out the scope of the quotas, the general provisions on what each rate already includes, the adjustment coefficients for working conditions such as height, radiation area and confined space, and the rules for measuring quantities; the chapter notes then add the conventions specific to each group of items. It replaces the 2015 edition. Note that the Chinese title says process equipment specifically, where the printed English says only mechanical equipment.

This part specifies the quotas for nuclear island process equipment installation engineering within the budget cost quota for nuclear power plant construction projects.

This part applies to the nuclear island works of newly built and extended pressurized water reactor nuclear power units, and also to the sub-items subject to nuclear safety requirements within BOP works, such as nuclear island liquid waste tank buildings, conventional island liquid waste tank buildings, radioactive solid waste treatment auxiliary buildings, solid waste interim storage facilities, radioactive machine repair shops and decontamination workshops. Other nuclear power reactor types and nuclear projects may use it for reference.
