Lessons learnt from severe accidents at NPPs are one of the main factors defining NPP progress. The paper is devoted to the consideration of these lessons in respect to instrumentation and control systems (I&C) of Ukrainian NPPs. The accident at Three Mile Island NPP has shown a lack of available methods of information presentation to personnel. The main conclusions of this accident in Ukraine was the creation (with support of USA organizations) of safety parameters display systems (SPDS), which were implemented at 11 units with VVER-1000. The tasks resulting from Chornobyl NPP accident for I&C systems mainly included the development of a new approach to ensuring safety culture by NPP personnel and I&C designers, state review of nuclear and radiation safety for all I&C important to safety, development of regulatory documents with requirements for I&C safety. The main challenges after Fukushima NPP accident were to perform stress-tests of I&C hardware, tighten requirements for I&C resistance to environment impacts, develop new systems (e.g., post-accident monitoring systems).

IntroductionThe COVID-19 pandemic has required the rapid development of comprehensive guidelines to direct health service organisation and delivery. However, most guidelines are based on resources found in high-income settings, with fewer examples that can be implemented in resource-constrained settings. This study describes the process of adapting and developing role-specific guidelines for comprehensive COVID-19 infection prevention and control in low-income and middle-income countries (LMICs).MethodsWe used a collaborative autoethnographic approach to explore the process of developing COVID-19 guidelines. In this approach, multiple researchers contributed their reflections, conducted joint analysis through dialogue, reflection and with consideration of experiential knowledge and multidisciplinary perspectives to identify and synthesise enablers, challenges and key lessons learnt.ResultsWe describe the guideline development process in the Philippines and the adaptation process in Sri Lanka. We offer key enablers identified through this work, including flexible leadership that aimed to empower the team to bring their expertise to the process; shared responsibility through equitable ownership; an interdisciplinary team; and collaboration with local experts. We then elaborate on challenges including interpreting other guidelines to the country context; tensions between the ideal compared with the feasible and user-friendly; adapting and updating with evolving information; and coping with pandemic-related challenges. Based on key lessons learnt, we synthesise a novel set of principles for developing guidelines during a public health emergency. The SPRINT principles are grounded in situational awareness, prioritisation and balance, which are responsive to change, created by an interdisciplinary team navigating shared responsibility and transparency.ConclusionsGuideline development during a pandemic requires a robust and time sensitive paradigm. We summarise the learning in the ‘SPRINT principles’ for adapting guidelines in an epidemic context in LMICs. We emphasise that these principles must be grounded in a collaborative or codesign process and add value to existing national responses.

Electric fields have been applied across oxides growing on a high temperature alloy and control of the oxidation of the material has been demonstrated. At present, three-fold increases in the oxidation rate have been measured in accelerating fields and the oxidation process has been completely stopped in a retarding field.The experiments have been conducted with an iron-base alloy, Pe 25Cr 5A1 0.1Y, although, in principle, any alloy capable of forming an adherent aluminum oxide layer during oxidation can be used. A specimen is polished and oxidized to produce a thin, uniform insulating layer on one surface. Three platinum electrodes are sputtered on the oxide surface and the specimen is reoxidized.
