LWR Chemistry and Component Integrity

The Annual LWR Chemistry and Component Integrity (LCC) Programme is focused on reactor coolant and RCS material issues. The overall objective of the LCC Program is to enable the LCC Member to gain increased understanding of reactor water chemistry related to a successful plant operation and continued integrity of Reactor Coolant System (RCS) materials while keeping radiation exposure low. This Programme was started in 2004 and has gained large interest.


We provide 10-15 seminars worldwide every year. There are different types of Seminars:

Tailored Seminars

Tailored Seminars on site of the Customer. The topics are selected by the Customer to fit their needs. Below are some characteristics of the Tailored Seminars:

  • The length varies from one to three days.
  • Your organisation pays one price – regardless of the number of attendants.
  • Your organisation can invite attendees from other organisations in your country/region if this is discussed on beforehand with the lecturer, as an effective way of cost sharing.
  • The topics of the Seminar are tailored to fit the needs of your organisation company.
  • All participants receive a CD with the presentation material before the seminar and a certificate after completing the seminar.
  • The tailored seminars are suitable for specialised engineers as well as engineers entering a new field.


A 2.5 day Seminar targeted towards more experienced engineers is included in the LCC programme to present the most recent published reports within the LCC programme by the authors.


There are two different Seminars, one for PWRs/VVERs and one for BWRs. The Seminars give an introduction and overview of water chemistry. Below are some characteristics of the Seminars:

  • The length is four days.
  • There is a fixed fee for each participant from each organisations but discounts are given for several participants from the same organisation.
  • Before the Seminar, the background information and presentation material will be made available to the participants.
  • After the Seminar, a certificate of seminar attendance will be issued by ANT International to the participants.

Handbooks & Reports

ANT International has up to now published more than 20 different Handbooks/Reports (200–500 pages each) on current BWR/PWR/VVER plant chemistry and corrosion issues. Each Handbook/Report is delivered in hardbound 4 colour print and as a high resolution searchable pdf-file on a CD-ROM. The electronic version of the report can be uploaded on a company server to allow all staff having access to the information.

Problem Solving

ANT International can provide expertise in the BWR/PWR plant chemistry and fuel design/manufacturing/performance areas. ANT International has noticed that customers would like to have some limited support (2-4 weeks) from experts and ANT International can provide such services. Dependent on the issue, we set up the perfect team of experts to resolve the issue. ANT International has provided this type of expert services during several years in the fuel area.

Examples of services performed:

  • Performance evaluation of new Zr alloy materials
  • Fuel Design Reviews
  • Auditing of Fuel Fabrication
  • Fuel failure root cause assessment and remedies


ANT International can now offer similar services in the plant chemistry area.


To quickly find the information you are looking for, ANT International has developed a Nuclear Wikipedia, AWIKI, based upon the Reports we have published. The AWIKI has similar structure as the Wikipedia with a powerful search tool to quickly retrieve the information you are interested in. The AWIKI will also direct you (via links) to information/reports with much more details. For each topic, all the relevant references are listed as well as suggestions on additional information contained in the ZIRAT/IZNA/LCC reports. The additional information is provided as pdf-files at the bottom of the topic to facilitate fast and easy access to the relevant information. The AWIKI is continuously updated with the most recent information. Only ZIRAT, IZNA or LCC Members can sign up for a subscription of the AWIKI.

The Experts

The A.N.T. International Network of experts providing the Products and Services were the leaders of the nuclear technical community that developed the current nuclear industry. A.N.T. International and the Network are independent, i.e., they do not rely on fuel/reactor vendors and the information provided in our products and services is unbiased and analysed with a bird eyes view on the business.
