BNFL – Nuclear Waste Flask Storage Yokes

Not only can Craven Concrete work fast but can work accurately as well. When we got details from BNFL of some yokes that were needed to store nuclear waste flasks our first reaction was ‘tricky but possible’. By the time we got the final drawings we had tolerances of +/- 0.5mm.

As you can see from the photograph, making the moulds for something this shape to the tolerances specified was no easy task. Every unit had to be checked individually for accuracy and out of nearly 2000 units we did not have one reject.

Fertiliser Solutions Ltd – Middlesbrough

Craven Concrete manufactured and erected a free-standing storage bunker 27 metres (88′) long, 48 metres (157′) wide & 6 metres (20′) high split with 3 double loading walls into 4 storage bunkers. The bunkers are now used for storing fertiliser. The support frames were designed by our consulting engineer to suit the prestressed panels we already manufactured. As you can see in the photographs the finished bunkers look pretty impressive.

Railtrack / Edmund Nuttall Ltd / W A Developments Ltd – Moorcock Viaduct

Craven Concrete were approached by W A Developments Ltd on behalf of Edmund Nuttall Ltd to tender for approximately 420 metres of precast units to strengthen the Moorcock Viaduct on the famous Settle to Carlisle railway line. We received an order for the units provided that half could be delivered within 3_ weeks from date of order and the rest only 5 days later. As you can imagine, time was not on our side.

We immediately started work on the seven moulds needed to enable us to meet the delivery date working day and night (well almost). In the meantime discussions were taking place about the possibility to cast 210m of centre drain units for the same project with the same delivery dates.

Only a fortnight before our deadline we received the order for the centre units; that left us with just 14 days to manufacture the moulds, cast and deliver the units. Despite many phone calls from a worried Production Manager at Nuttalls we managed to deliver everything on time.
