[en] The World Association of Nuclear Operators was formed by nuclear utilities to raise safety standards. One of the early priorities of WANO, was to establish a programme of East-West exchange visits between nuclear plants. As described here, that goal has been accomplished with a remarkable degree of success. (author)

[en] Nuclear power continues to make a major contribution to world electricity supplies. But the capacity of new reactors entering service and new construction starts in the past twelve months was almost exactly offset by the capacity of reactors shut down for decommissioning and halts on construction. The details are given in a country-by-country survey of developments in 1989. The most notable development in the nuclear scene in the past year has been the reassessment of the safety of the Soviet reactors in operation and under construction in Eastern European countries following the political changes there. This is a major setback to their nuclear plans, even though it opens up prospects for work from Western companies for safety systems and complete reactors. The general commitment to improving performance and safety standards was clearly emphasised in the signing of the charter of the World Association of Nuclear Operators (WANO) by 138 utility executives, representing between them every operating nuclear plant in the world.

[en] Answers are given by the chairman of the World Association of Nuclear Operators, Lord Marshall, to questions about the recently formed Users Group for Soviet-Designed Reactors which the Association sponsors. The questions covered the following areas: the response of Western companies to the Users Group; the kinds of projects the Group will be proposing, and the improvements to Soviet designed reactors they would like to see; the issue of liability; the role of the Group alongside other organisations in improving the safety of Soviet designed reactors; the recent report of the International RBMK Safety Consortium; the efforts of the International Atomic Energy Agency with respect to Soviet designed reactors.

[en] The chairman of the governing body of the World Association of Nuclear Operators (WANO) has recently commented on the hold-up of improvements to east European reactors due to delays in the provision of funding by western nations. At Chernobyl, two of the four reactors are still in operation. The main defects which led to the disaster in 1986 have been corrected in these and all similar RBMKs. But desirable improvements remain to be carried out to eliminate the risk of minor accidents. The west is criticized for committing too much funding to western engineering studies. The emphasis should now be on enabling eastern operators to buy and install new equipment. Technology transfer is also important so that equipment can be made locally and more cheaply. WANO is increasingly concerned by conditions attached to grants from 67 countries which are administered by the European Bank for Reconstruction and Development. The Bank is singled out for criticism over delays in funding safety improvements to older reactors. (UK)

[en] This paper briefly describes the background to the formation of WANO (World Association of Nuclear Operators) and goes on to discuss its aims and objectives. It lists the programmes which have been established and assesses their effectiveness in improving the safety and reliability of nuclear power plants worldwide. (Author)

[en] Conclusions: • DBKM is a very large task in terms of: – the amount and variety of data; – the variety of the form of the data; – the number of places in which it is held; – the tools needed to handle it. • Worldwide, it is not handled well: • There are some fundamental barriers which must be addressed if improvements are to be made. •The IAEA can provide a forum to address these barriers. • A TECDOC may help. • Other fora for utilities to develop workable systems are essential. • WANO, INPO and the new safety construct initiative should discuss these issues

[en] WANO (World Association of Nuclear Operators) implemented a program known as PEER REVIEW at the Santa Maria de Garona NPP in 1996. It was as follows, an international team consisting of professionals with experience in nuclear power plants observed different activities in the plant, hold interviews and meetings, and finally they checked all the information during three weeks, in order to compare the plant with the WANO's Excellence Criteria at work. The result was that the plant was in a good state and most of the implemented activities and practices of work were done properly, further the usual demands and rules. However it was noticed that some of the activities could be improved, If we compare them with the optimum practices. The plant started a work plan defined as an objective in the COMPANY PROJECT it self, in order to implement the corrective actions which could resolve the proposed improvements by WANO. Following the PEER REVIEW program, approximately one year and a half later, a WANO team came back to the plan for a week in June 1998, they came back to implement what is known as a FOLLOW UP, that is today, a control resting on the monitoring of facts of the fulfillment level for the improvements which had been recommended. After finishing this monitoring work, the result of the FOLLOW UP was that the plant has attained a very remarkable implantation of the recommendations showed in the PEER REVIEW. (Author)

[en] The paper will cover the review of WANO SOER 2007-1 from a Control Room Operations point of view. It will answer the question: what recommendations are possible to implement at the Authorized Nuclear Operator(ANO) and Control Room Shift Supervisor(CRSS) level? History has indicated that reactivity management events continue to happen in NPP's all over the world. This paper will discuss how the ANO/CRSS as the final barrier can improve this trend. The paper will be written as a descriptive piece. The paper will metaphorically examine the role of the Control Room Operations staff in reactivity management control and safety. (author)
