On aspects of safety, the CEGB provide lectures from their own Health and Safety Branch, as well as some external lectures where appropriate. The SSEB are catered for at Oldbury for these initial courses, although they have their own simulator machines available, at, for example, Hunterston, to take care of the practical training requirements at SSEB stations. 

Appendix 12E Visit to Hunterston W Nuclear Power Station to attend an Emergency Exercise... 

A visit to Hunterston was made on 11-12 May 1987 by Norman Worley and Glynne Lewis on behalf of the Watt Committee Working Group on the Chernobyl Accident and its Implications. The attendance at the emergency exercise on 12 May was by the kind permission of the South of Scotland Electricity Board. 

Tests and emergency exercises are carried out regularly at all nuclear stations throughout the United Kingdom. The Watt Committee on Energy attended the exercise at Hunterston in order to see how such operations are conducted.

Visual inspection provided enough information for most purposes with the main exception of the core restraint structure and this accounts for the majority of in service inspection work at Hunterston A. ...

BEG(UK)L operates two AGR stations (Hunterston B and Tomess) in Scotland. The company s Route 21 downsizing plans had been based on a predicted reduction in workload. Here, the Nil found that the company s workload had decreased, although not as much as predicted. The approved change management process at BEG(UK)L also required staff members to be retained in their posts imtil the workload had actually decreased, and the Nil foimd that this requirement had been honored. 

The South of Scotland Electricity Board s nuclear generating station at Hunterston, on the Ayrshire coast, is one of the first three civil stations - each with an electrical output of about 300 MW from two reactors - to be built under the government s nuclear power programme of 1957. 

Each reactor at Hunterston is associated with a group of eight steam-raising units feeding three 60 MW turbo alternators. The station operates on the base load and feeds electricity into the 275 kV grid at Nielston, Renfrewshire.

However, the Oldbury contractors carried out optimisation studies on the UK Hinkley B and Hunterston B power stations. Slight changes in the vessel parameters were inevitable. This time true helices were adopted for the prestressing tendons rather than the barrelised type adopted for the Oldbury... 

The quantity and disposition of main bonded reinforcement in the Hunterston— B P C P V is taken as a typical case study. In this chapter covering only main and local bonded reinforcement are covered. An attempt has been made to discover the need and function of main bonded steel in the prestressed concrete cylindrical pressure vessel. The same is adhered to the containment vessel. At present there is no established method available to determine the amount of such steel needed in the vessel and to adjudge its performance during working and overload conditions of the vessel. 

In Hunterston B , a desirable assumption is made that the bonded reinforcement is capable of maintaining a strain of 100 micro-strain throughout the vessel in order to assist in the formation of a well-disposed crack pattern, hence a strain of 100 X 10 can be propagated if the percentage reinforcement is of the order 250... 

The first two of the AGR stations, Hinkley Point B and Hunterston B, came on line in 1976. The success of the program will depend on the avoidance of further corrosion or vibration damage, particularly in the extremely complicated region above the reactor core, where repair work would be exceptionally difficult.

Transferring the design from Bradwell clay to Hunterston rock added to the cost. Other changes were required after the tender was evaluated by the AEA, so that price for the civil work done at Hunterston was nearly 6 million more than for Bradwell.
