Three technical personnel—two from NDDC, Yusipang and one from RLDC, Kanglung are undergoing an 8-day (6-13 April) specialized training program on the operation and maintenance of Liquid Nitrogen (LN₂) plants at IMTEK Cryogenics, Ankara, Turkey with financial support from the World Bank–funded RNR Jobs Project.
At present, the Department operates three LN₂ plants—two at NDDC, Yusipang and one at RLDC, Kanglung—which play a pivotal role in supporting the national artificial insemination (AI) programme. These plants ensure the continuous production and supply of liquid nitrogen essential for the cryopreservation of bovine semen distributed to AI centres across the country, as well as for maintaining on-station semen banks. As such, the reliability and efficiency of LN₂ production systems are critical for sustaining dairy breed improvement initiatives and enhancing livestock productivity nationwide.
The training program is designed to equip participants with a comprehensive understanding of cryogenic science and the complete liquid nitrogen production cycle. It will enable them to thoroughly understand the functions and interrelationships of key plant components, and to confidently undertake plant start-up, operation, and shutdown procedures in accordance with standard protocols. Participants will also gain practical skills in monitoring and managing critical operational parameters such as pressure, temperature, and nitrogen purity to ensure optimal plant performance.
In addition, the training emphasizes routine and preventive maintenance practices, enabling staff to detect early signs of system inefficiencies and undertake timely corrective measures. Strong focus is also placed on safety management, including risk identification and mitigation associated with cryogenic operations, thereby ensuring safe handling and operation of LN₂ systems. Furthermore, the program will build competencies in troubleshooting common technical issues, adhering to standard operating procedures, and maintaining operational records for improved system management.
Overall, this capacity-building initiative is expected to significantly strengthen in-house technical expertise within the Department. It will reduce dependence on external service providers, minimize plant downtime, and enhance operational efficiency. Most importantly, it will ensure a reliable and uninterrupted supply of liquid nitrogen to AI centres nationwide, thereby directly contributing to the success of the national dairy breeding program and supporting the broader goals of livestock sector development and rural livelihoods in Bhutan.
