This work , which continues today with ORNL as the lead laboratory , has included development and testing of the reactor 's graphite core structure and ceramic-coated particle fuel , the key components that determine the reactor 's exceptional safety and high fuel efficiency . From evidence collected in discussions and observations , it appears that students of French make limited use of the language laboratory , visual aids centre or IT facilities . Staff of the New York program have been active in national and international newborn screening activities , providing leadership in development of guidelines for operation of newborn screening programs , followup and diagnosis of infants after identification by the testing laboratory , storage and use of the residual specimens when testing is finished , and most recently in developing national standards for adoption of a screening panel . Normally , the Board meets at least twice per year , once in May to review proposed budgets for Seed Services and the Seed Laboratory , and once in December to review issues and budget updates . Technical personnel of the testing laboratory , using internal categorization standards , performed the assessments and assigned the characterizations of the hair by color and curvature . Subsequently fewer samples were received in the DNA Laboratory , but still 3 of the 8 confirmed cases did not have the common mutation and 1 baby had only one copy of the common mutation detected .
