Standard Operating Procedure Number 1101 6/1/1965

Heatup from Cold Iron Condition

GENERAL PLANT STARTUP PROCEDURE

Part I

HEATUP FROM COLD IRON CONDITION

GENERAL:

The purpose of this procedure is to indicate the steps to be followed in taking the plant from the cold iron condition to the condition of decay head removal. The normal startup from the decay heat removal condition will proceed according to SOP 1101, Part II.

PROCEDURE:

Part II

Startup from Decay Heat Removal Condition

General:

This procedure as written sets forth the steps for starting up the plant. It is written in a fashion such that, for the assumed plant conditions, the steps are to be followed sequentially. There may frequently occur variations from these assumed conditions as the time of ant particular startup; accordingly, departure from the sequence as written my be authorized by the First Assistant Engineer to meet the needs and requirements which may exist at the time.

PLANT CONDITIONS:

PRE-STARTUP OPERATIONS

PRIMARY SYSTEM WARMUP:

NOTE: Temperature increase in the Primary System is limited to 35F per hour, and in the Pressurizer it is limited to 70 F per hour.

[If the system is warmed up too quickly, the metal on the inside of the various pressure vessels will expand more than the metal on the outside of the vessel and cause thermal stress. At 35F per hour, there is enough time for the pressure vessel walls to warm up through their entire thickness.]
